with 3–State Control Inputs
The MC74VHCT126A is a high speed CMOS quad bus buffer
fabricated with silicon gate CMOS technology. It achieves
noninverting high speed operation similar to equivalent Bipolar
Schottky TTL while maintaining CMOS low power dissipation.
The MC74VHCT126A requires the 3–state control input (OE) to be
set Low to place the output into high impedance.
http://onsemi.com
The VHCT inputs are compatible with TTL levels. This device can
be used as a level converter for interfacing 3.3V to 5.0V, because it has
full 5V CMOS level output swings.
The VHCT126A input structures provide protection when voltages
between 0V and 5.5V are applied, regardless of the supply voltage.

The output structures also provide protection when V
= 0V. These
CC
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 buffer
output which provides high noise immunity and stable output. The
inputs tolerate voltages up to 7V, allowing the interface of 5V systems
to 3V systems.
