General DescriptionThe MAX4644 is a single-pole/double-throw (SPDT)switch that operates from a single supply ranging from+1.8V to +5.5V. It provides low 4Ωon-resistance (RON)as well as 1ΩRONflatness over the entire analog signalrange. The MAX4644 offers fast switching times of lessthan 20ns while ensuring break-before-make operation.It typically consumes only 0.01µW of quiescent power,making it suitable for use in low-power, portable appli-cations.The MAX4644’s features include low leakage currentsover the entire temperature range, TTL/CMOS-compati-ble digital logic, and excellent AC characteristics. It ispackaged in either a small 8-pin µMAX or a tiny 6-pinSOT23.________________________ApplicationsBattery-Operated EquipmentAudio and Video Signal RoutingLow-Voltage Data-Acquisition SystemsSample-and-Hold Circuits
General Description
The MAX3000E/MAX3001E/MAX3002–MAX3012
8-channellevel translators provide the level shifting nec-
essary to allow data transfer in a multivoltage system.
Externally applied voltages, V
CCand V
L, set the logic lev-
els on either side of the device. Logic signals present on
the V
Lside of the device appear as a higher voltage logic
signal on the V
CCside of the device, and vice-versa.
The MAX3000E/MAX3001E/MAX3002/MAX3003 use an
architecture specifically designed to be bidirectional
without the use of a directional pin.
The MAX3000E/MAX3001E/MAX3002/MAX3004–MAX3012
feature an EN input that, when low, reduces the V
CCand
V
Lsupply currents to < 2µA. The MAX3000E/MAX3001E
also have ±15kV ESD protection on the I/O V
CC side for
greater protection in applications that route signals
externally. The MAX3000E operates at a guaranteed data
