MC74VHCT540A
Octal Bus Buffer
Inverting
The MC74VHCT540A is an advanced high speed CMOS inverting
octal 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 MC74VHCT540A features inputs and outputs on opposite
sides of the package and two ANDed activelow output enables.
When either OE1 or OE2 are high, the terminal outputs are in 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 VHCT540A input and output (when disabled) structures
provide protection when voltages between 0 V and 5.5 V are applied,
regardless of the supply voltage. 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.
