DESCRIPTION
The M54/74HCT540 and HCT541 are high speed
CMOS
OCTAL
BUS
fabricated in silicon gate C
2
MOS technology. They
have the same high speed performance of LSTTL
combined withtrue CMOS lowpower 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 ifeither G1 and G2 are high,all eight
outputs are in the highimpedance 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
BUFFERS
(3-STATE)
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 HSC
2
MOS 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.
