DESCRIPTION

The M54/74HCT540 and HCT541 are high speed

CMOS OCTAL BUS BUFFERS (3-STATE)

fabricated in silicon gate C²MOS technology. They

have the same high speed performance of LSTTL

combined with true CMOS low power consumption.

The HCT540 is an inverting buffer and HCT541 is a

non inverting buffer.

The 3 STATE control gate operates as a two input

AND such that if either G1 and G2 are high, all eight

outputs are in the high impedance state. In order to

enhance PC board layout, the HCT540 and

HCT541 offers a pinout having inputs and outputs

on opposite sides of the package. All inputs are

equipped with protection circuits against static

discharge and transient excess voltage.

This integrated circuit has input and output

characteristics that are fully compatible with 54/74

LSTTL logic families. M54/74HCT devices are

designed to directly interface HSC²MOS systems

with TTL and NMOS components. They are also

plug in replacements for LSTTL devices giving a

reduction of power consumption.

IT IS PROHIBITED TO APPLY A SIGNAL TO BUS

TERMINAL WHEN IT IS IN OUTPUT MODE.

WHEN A BUS TERMINAL IS FLOATING (HIGH

IMPEDANCE STATE) IT IS REQUESTED TO FIX

THE INPUT LEVEL BY MEANS OF EXTERNAL

PULL DOWN OR PULL UP RESISTOR.
