Schmitt-Trigger Inverter/ CMOS Logic Level Shifter
with LSTTL–Compatible Inputs
MC74VHC1GT14
The MC74VHC1GT14 is a single gate CMOS Schmitt–trigger inverter 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 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 MC74VHC1GT14 input structure provides protection when voltages up to 7 V are applied, regardless of the supply voltage. This
allows the MC74VHC1GT14 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. The MC74VHC1GT14 can be used to enhance noise immunity or to square up slowly changing waveforms.
• High Speed: t PD = 4.5 ns (Typ) at V CC = 5 V
• Low Power Dissipation: I CC = 2 mA (Max) at T A = 25°C
• TTL–Compatible Inputs: V IL = 0.8 V; V IH = 2.0 V
• CMOS–Compatible Outputs: V OH > 0.8 V CC ;
V OL < 0.1 V CC @ Load
• Power Down Protection Provided on Inputs and Outputs
• Balanced Propagation Delays
• Pin and Function Compatible with Other Standard Logic
Families
• Chip Complexity: FETs = 100; Equivalent Gates = 25
