Overview

MC74VHCT125A Quad Bus Buffer with 3−State Control Inputs The MC74VHCT125A is a high speed CMOS quad bus buffer fabricated with silicon gate CMOS technology.
It achieves high speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation.
The MC74VHCT125A requires the 3−state control input (OE) to be set High to place the output into the 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 VHCT125A input structures provide protection when voltages between 0 V and 5.
5 V are applied, regardless of the supply voltage.
The output structures also provide protection when VCC = 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 internal circuit is composed of three stages, including a buff...
