General DescriptionThe MAX3311/MAX3313 are low-power, +5V EIA/TIA-232-compatible transceivers. Both devices have one transmitter and one receiver. The transceivers have a proprietary low-dropout transmitter output stage enabling RS-232-compatible operation from a +5V sup-ply with a single inverting charge pump. These devices require only three 0.1µF capacitors and will run at data rates up to 460kbps while maintaining RS-232-compati-ble output levels.The MAX3311 features a 1µA shutdown mode. In shut-down the device turns off the charge pump, pulls V- to ground, and the transmitter output is disabled. The MAX3313 features an INVALID output that asserts high when an active RS-232 cable signal is connected, sig-naling to the host that a peripheral is connected to the communication port.________________________ApplicationsDigital Cameras PDAs GPS POSTelecommunications Handy Terminals Set-Top BoxesFeatureso 1µA Low-Power Shutdown (MAX3311)o INVALID Output (MAX3313)o Receiver Active in Shutdown (MAX3311)o Single Transceiver (1Tx/1Rx) in 10-Pin µMAX o RS-232-Compatible OperationMAX3311/MAX3313460kbps, 1µA Supply Current,RS-232-Compatible Transceivers in µMAX________________________________________________________________Maxim Integrated Products 1Pin Configurations19-1901; Rev 0; 2/01Ordering InformationFor price, delivery, and to place orders,please contact Maxim Distribution at 1-888-629-4642,or visit Maxim’s website at .Typical Operating CircuitM A X 3311/M A X 3313460kbps, 1µA Supply Current,RS-232-Compatible Transceivers in µMAX 2_________________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSELECTRICAL CHARACTERISTICSStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

The charge pump operates in a discontinuous mode and requires a flying capacitor (C1) and a reservoir capacitor (C2) to gener-ate the V- supply.RS-232-Compatible DriverThe transmitter is an inverting level translator that con-verts CMOS-logic levels to EIA/TIA-232-compatible lev-els. It guarantees data rates up to 460kbps with worst-case loads of 3k Ωin parallel with 1000pF. When SHDN is driven low, the transmitter is disabled and put into three state. The transmitter input does not have an internal pullup resistor.RS-232 ReceiverThe MAX3311/MAX3313 receiver converts RS-232 sig-nals to CMOS-logic output levels. The MAX3311 receiv-er will remain active during shutdown mode. The MAX3313 INVALID indicates when an RS-232 signal is present at the receiver input, and therefore when the port is in use.The MAX3313 INVALID output is pulled low when no valid RS-232 signal level is detected on the receiver input.MAX3311 Shutdown ModeIn shutdown mode, the charge pump is turned off, V- is pulled to ground, and the transmitter output is disabled (Table 1). This reduces supply current typically to 1µA.The time required to exit shutdown is typically less than 100µs.Applications InformationCapacitor SelectionThe capacitor type used for C1 and C2 is not critical for proper operation; either polarized or nonpolarized capacitors are acceptable. If polarized capacitors are used, connect polarity as shown in the Typical Operating Circuit . The charge pump requires 0.1µF capacitors. Increasing the capacitor values (e.g., by afactor of 2) reduces power consumption. C2 can be increased without changing C1’s value. However, do not increase C1’s value without also increasing the value of C2 and C BYPASS to maintain the proper ratios (C1 to the other capacitors).When using the minimum 0.1µF capacitors, make sure the capacitance does not degrade excessively with temperature. If in doubt, use capacitors with a larger nominal value. The capacitor ’s equivalent series resis-tance (ESR) usually rises at low temperatures and influ-ences the amount of ripple on V-.To reduce the output impedance at V-, use larger capacitors (up to 10µF).Bypass V CC to ground with at least 0.1µF. In applica-tions sensitive to power-supply noise generated by the charge pump, decouple V CC to ground with a capaci-tor the same size as (or larger than) charge-pump capacitors C1 and C2.Transmitter Output when ExitingShutdownFigure 1 shows the transmitter output when exiting shutdown mode. The transmitter is loaded with 3k Ωin parallel with 1000pF. The transmitter output displays no ringing or undesirable transients as the MAX3311comes out of shutdown. Note that the transmitter is enabled only when the magnitude of V- exceeds approximately -3V.Figure 1.

+3.3V, ±15kV ESD-Protected, Fail-Safe, Hot-Swap, RS-485/RS-422 Transceivers

General DescriptionThe MAX3311E/MAX3313E are low-power, 5V EIA/TIA-232-compatible transceivers. All transmitter outputs and receiver inputs are protected to ±15kV using the Human Body Model, making these devices ideal for applications where more robust transceivers are required.Both devices have one transmitter and one receiver.The transmitters have a proprietary low-dropout trans-mitter output stage enabling RS-232-compatible opera-tion from a +5V supply with a single inverting charge pump. These transceivers require only three 0.1µF capacitors and will run at data rates up to 460kbps while maintaining RS-232-compatible output levels.The MAX3311E features a 1µA shutdown mode. In shutdown the device turns off the charge pump, pulls V- to ground, and the transmitter output is disabled.The MAX3313E features an INVALID output that asserts high when an active RS-232 cable signal is connected,signaling to the host that a peripheral is connected to the communication port.________________________ApplicationsDigital Cameras PDAs GPS POSTelecommunications Handy Terminals Set-Top BoxesFeatureso ESD Protection for RS-232-Compatible I/O Pins±15kV—Human Body Modelo 1µA Low-Power Shutdown (MAX3311E)o INVALID Output (MAX3313E)o Receiver Active in Shutdown (MAX3311E)o Single Transceiver (1Tx/1Rx) in 10-Pin µMAX PackageMAX3311E/MAX3313E±15kV ESD-Protected, 460kbps, 1µA,RS-232-Compatible Transceivers in µMAX________________________________________________________________Maxim Integrated Products1Pin Configurations19-1910; Rev 0; 1/01Ordering InformationFor price, delivery, and to place orders,please contact Maxim Distribution at 1-888-629-4642,or visit Maxim’s website at .Typical Operating CircuitM A X 3311E /M A X 3313E±15kV ESD-Protected, 460kbps, 1µA,RS-232-Compatible Transceivers in µMAX 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSELECTRICAL CHARACTERISTICSStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

The MAX3313E INVALID indicates when an RS-232 signal is present at the receiver input, and therefore when the port is in use.The MAX3313E INVALID output is pulled low when no valid RS-232 signal level is detected on the receiver input.MAX3311E Shutdown ModeIn shutdown mode, the charge pump is turned off, V- is pulled to ground, and the transmitter output is disabled (Table 1). This reduces supply current typically to 1µA.The time required to exit shutdown is less than 25ms.Applications InformationCapacitor SelectionThe capacitor type used for C1 and C2 is not critical for proper operation; either polarized or nonpolarized capacitors are acceptable. If polarized capacitors are used, connect polarity as shown in the Typical Operating Circuit . The charge pump requires 0.1µF capacitors. Increasing the capacitor values (e.g., by a factor of 2) reduces power consumption. C2 can beincreased without changing C1’s value. However, do not increase C1’s value without also increasing the value of C2 and C BYPASS to maintain the proper ratios (C1 to the other capacitors).When using the minimum 0.1µF capacitors, make sure the capacitance does not degrade excessively with temperature. If in doubt, use capacitors with a larger nominal value. The capacitor ’s equivalent series resis-tance (ESR) usually rises at low temperatures and influ-ences the amount of ripple on V-.To reduce the output impedance at V-, use larger capacitors (up to 10µF).Bypass V CC to ground with at least 0.1µF. In applica-tions sensitive to power-supply noise generated by the charge pump, decouple V CC to ground with a capaci-tor the same size as (or larger than) charge-pump capacitors C1 and C2.Transmitter Output when ExitingShutdownFigure 1 shows the transmitter output when exiting shutdown mode. The transmitter is loaded with 3k Ωin parallel with 1000pF. The transmitter output displays no ringing or undesirable transients as the MAX3311E comes out of shutdown. Note that the transmitter is enabled only when the magnitude of V- exceeds approximately -3V.High Data RatesThe MAX3311E/MAX3313E maintain RS-232-compati-ble ±3.7V minimum transmitter output voltage even atMAX3311E/MAX3313E±15kV ESD-Protected, 460kbps, 1µA,RS-232-Compatible Transceivers in µMAX5Figure 1.

Figure 3 shows the loopback test result at 120kbps, and Figure 4 shows the same test at 250kbps.±15kV ESD ProtectionAs with all Maxim devices, ESD-protection structures are incorporated on all pins to protect against electro-static discharges encountered during handling and assembly. The MAX3311E/MAX3313E driver outputsand receiver inputs have extra protection against static discharge. Maxim ’s engineers have developed state-of-the-art structures to protect these pins against ESD of ±15kV without damage. The ESD structures withstand high ESD in all states: normal operation, shutdown, and powered down. After an ESD event, Maxim ’s E versions keep working without latchup; whereas, competing products can latch and must be powered down to remove latchup.ESD protection can be tested in various ways. The transmitter outputs and receiver inputs of the product family are characterized for protection to ±15kV using the Human Body Model.ESD Test ConditionsESD performance depends on a variety of conditions.Contact Maxim for a reliability report that documents test setup, test methodology, and test results.Human Body ModelFigure 5 shows the Human Body Model, and Figure 6shows the current waveform it generates when dis-charged into low impedance. This model consists of a 100pF capacitor charged to the ESD voltage of interest,which is then discharged into the test device through a 1.5k Ωresistor.Machine ModelThe Machine Model for ESD tests all pins using a 200pF storage capacitor and zero discharge resis-tance. Its objective is to emulate the stress caused by contact that occurs with handling and assembly during manufacturing. Of course, all pins require this protec-tion during manufacturing, not just RS-232 inputs and outputs. Therefore, after PC board assembly, the Machine Model is less relevant to I/O ports.Figure 4.
