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 AND–ed active–low 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 3.3V to 5.0V, because it has full 5V CMOS
level output swings.
The VHCT540A input and output (when disabled) structures provide
protection when voltages between 0V and 5.5V 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 7V, allowing the interface of 5V systems to 3V systems.
