DESCRIPTION
The M54/74HCT245, HCT640 and HCT643 utilise
silicon gate C
2
MOS technology to achive operating
speedseqivalent to LSTTL devices.
Alongwith the lowpower dissipation and high noise
immunity of standad CMOS integrated circuit, it
possesses the capability to drive 15 LSTTL loads.
These IC’s are intended fortwo-way asynchronous
communication between data buses, and the
direction of data trasmission is determined by DIR
input. The enable input (G) can be used to disable
the device so thatthe busesare effectively isolated.
All input are equipped with protection circuits
against static discharge and transient discharge.
These integrated circuits have 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 A
BUS TERMINAL WHEN IT IS IN OUTPUT MODE
AND WHEN A BUS THERMINAL IS FLOATING
(HIGH IMPEDANCE STATE), IT IS REQUESTED
TO FIX THE INPUT LEVEL BY MEANS OF
EXTERNAL
