2-Input NOR Gate / CMOS Logic Level Shifter
with LSTTL–Compatible Inputs
MC74VHC1GT02
The MC74VHC1GT02 is a single gate 2–input NOR fabricated with silicon gate CMOS technology. It achieves high speed operation
similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation.
The internal circuit is composed of three stages, including a buffer output which provides high noise immunity and stable output.
The device input is compatible with TTL–type input thresholds and the output has a full 5.0 V CMOS level output swing. The input
protection circuitry on this device allows overvoltage tolerance on the input, allowing the device to be used as a logic–level translator from
3.0 V CMOS logic to 5.0 V CMOS Logic or from 1.8 V CMOS logic to 3.0 V CMOS Logic while operating at the high–voltage power
supply.
The MC74VHC1GT02 input structure provides protection when voltages up to 7 V are applied, regardless of the supply voltage. This
allows the MC74VHC1GT02 to be used to interface 5 V circuits to 3 V circuits. The output structures also provide protection when
V CC = 0 V. These input and output structures help prevent device destruction caused by supply voltage – input/output voltage mismatch,
battery backup, hot insertion, etc.
• High Speed: tPD = 4.7 ns (Typ) at VCC = 5 V
• Low Power Dissipation: ICC = 2 mA (Max) at TA = 25°C • Balanced Propagation Delays
• TTL–Compatible Inputs: VIL = 0.8 V; VIH = 2.0 V
• Pin and Function Compatible with Other Standard Logic Families
• CMOS–Compatible Outputs: VOH > 0.8 VCC ; VOL < 0. • Chip Complexity: FETs = 65; Equivalent Gates = 14
1 VCC @Load
• Power Down Protection Provided on Inputs and Outputs
