MC74VHC1GT125  
Noninverting Buffer /  
CMOS Logic Level Shifter  
with LSTTL−Compatible Inputs  
The MC74VHC1GT125 is a single gate noninverting buffer  
fabricated with silicon gate CMOS technology. It achieves high speed  
operation similar to equivalent Bipolar Schottky TTL while  
maintaining CMOS low power dissipation.

MARKING  
The MC74VHC1GT125 requires the 3−state control input (OE) to  
be set High to place the output into the high impedance state.  
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 V  
CMOS logic to 5 V CMOS Logic or from 1.8 V CMOS logic to 3 V  
CMOS Logic while operating at the high−voltage power supply.  
The MC74VHC1GT125 input structure provides protection when  
voltages up to 7 V are applied, regardless of the supply voltage. This  
allows the MC74VHC1GT125 to be used to interface 5 V circuits to  
3 V circuits. The output structures also provide protection when
