This device can be used to interface 5V to 3V.All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.74VHC1383 TO 8 LINE DECODER (INVERTING)Figure 1: Pin Connection And IEC Logic SymbolsTable 1: Order CodesPACKAGE T & R SOP 74VHC138MTR TSSOP74VHC138TTR74VHC1382/12Figure 2: Input Equivalent CircuitTable 2: Pin DescriptionTable 3: Truth TableX : Don’t careFigure 3: Logic DiagramThis logic diagram has not be used to estimate propagation delaysPIN N°SYMBOL NAME AND FUNCTION 1, 2, 3A, B, C Address Inputs 4, 5G2A, G2BEnable Inputs 6G1Enable Input 15, 14, 13, 12, 11, 10, 9,7Y0 to Y7Outputs8GND Ground (0V)16V CCPositive Supply VoltageINPUTSOUTPUTS ENABLE SELECTG2B G2A G1C B A Y0Y1Y2Y3Y4Y5Y6Y7X X L X X X H H H H H H H H X H X X X X H H H H H H H H H X X X X X H H H H H H H H L L H L L L L H H H H H H H L L H L L H H L H H H H H H L L H L H L H H L H H H H H L L H L H H H H H L H H H H L L H H L L H H H H L H H H L L H H L H H H H H H L H H L L H H H L H H H H H H L H LLHHHHHHHHHHHL74VHC1383/12Table 4: Absolute Maximum RatingsAbsolute Maximum Ratings are those values beyond which damage to the device may occur.

It is ideal for low power, battery operated and low noise 3.3V applications.The internal circuit is composed of 3 stages including buffer output, which provides high noise immunity and stable output.Power down protection is provided on all inputs and 0 to 7V can be accepted on inputs with no regard to the supply voltage.This device can be used to interface 5V to 3V system. It combines high speed performance with the true CMOS low power consumption. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.74LVX02LOW VOLTAGE CMOS QUAD 2-INPUT NOR GATEWITH 5V TOLERANT INPUTSFigure 1: Pin Connection And IEC Logic SymbolsTable 1: Order CodesPACKAGE T & R SOP 74LVX02MTR TSSOP74LVX02TTR74LVX022/11Figure 2: Input Equivalent CircuitTable 2: Pin DescriptionTable 3: Truth TableTable 4: Absolute Maximum RatingsAbsolute Maximum Ratings are those values beyond which damage to the device may occur.

MC74VHCT574A Octal D-Type Flip-Flop with 3-State OutputThe MC74VHCT574A is an advanced high speed CMOS octal flip −flop with 3−state output fabricated with silicon gate CMOS technology. It achieves high speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation.This 8−bit D −type flip −flop is controlled by a clock input and an output enable input. When the output enable input is high, the eight outputs are in a high impedance state.The VHCT inputs are compatible with TTL levels. This device can be used as a level converter for interfacing 3.3 V to 5.0 V , because it has full 5.0 V CMOS level output swings.The VHCT574A input and output (when disabled) structures provide protection when voltages between 0 V and 5.5 V are applied,regardless of the supply voltage. These input and output structures h e l p p r e v e n t d e v i c e d e s t r u c t i o n c a u s e d b y s u p p l y voltage −input/output voltage mismatch, battery backup, hot insertion,etc.Features•High Speed: f max = 140 MHz (Typ) at V CC = 5.0 V•Low Power Dissipation: I CC = 4 m A (Max) at T A = 25°C •TTL −Compatible Inputs: V IL = 0.8 V; V IH = 2.0 V•Power Down Protection Provided on Inputs and Outputs •Balanced Propagation Delays•Designed for 4.5 V to 5.5 V Operating Range •Low Noise: V OLP = 1.6 V (Max)•Pin and Function Compatible with Other Standard Logic Families •Latchup Performance Exceeds 300 mA •ESD Performance:Human Body Model > 2000 V;Machine Model > 200 V•Chip Complexity: 286 FETs or 71.5 Equivalent Gates •These Devices are Pb −Free and are RoHS CompliantSee detailed ordering and shipping information in the package dimensions section on page 4 of this data sheet.ORDERING INFORMATIONMARKING DIAGRAMS201−20SUFFIX DT CASE 948E−20WB SUFFIX DWCASE 751DVHCT 574A ALYW GG1A =Assembly Location WL, L =Wafer Lot YY , Y =YearWW, W =Work Week G or G = Pb −Free Package(Note: Microdot may be in either location)FUNCTION TABLEFigure 1.

Designed for use as an interface between a 5V bus and a 3.3V bus in a mixed 5V/3.3V supply systems, it achieves high speed operation while maintaining the CMOS low power dissipation.This IC is intended for two-way asynchronous communication between data buses and the direction of data transmission is determined by DIR input. The enable input G can be used to disable the device so that the buses are effectively isolated.The A-port interfaces with the 5V bus, the B-port with the 3.3V bus.All inputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.74LVX4245OCTAL DUAL SUPPLY BUS TRANSCEIVERTable 1: Order CodesPACKAGE T & R SOP 74LVX4245MTR TSSOP74LVX4245TTR74LVX42452/13Figure 2: Input And Output Equivalent CircuitTable 2: Pin DescriptionTable 3: Truth TableX : Don’t CareZ : High ImpedanceTable 4: Absolute Maximum RatingsAbsolute Maximum Ratings are those values beyond which damage to the device may occur.
