MC74VHCT126A

Quad Bus Buffer

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.

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 VHCT126A 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 V

= 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 buffer

output which provides high noise immunity and stable output. The

inputs tolerate voltages up to 7.0 V, allowing the interface of 5.0 V

systems to 3.0 V systems.
