SEMICONDUCTOR TECHNICAL DATA

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.

DW SUFFIX

20–LEAD SOIC WIDE PACKAGE

CASE 751D–05

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.

DT SUFFIX

20–LEAD TSSOP PACKAGE

CASE 948E–02

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.
