DESCRIPTION
The M54/74HC245, HC640 and HC643 utilise
silicon gate C2MOStechnology to achive operating
speedsequivalent to LSTTL devices.
Alongwith the lowpower dissipation and high noise
immunity of standards C
2
MOS 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 staticdischarge andtransientdischarge and
transient excess voltage.
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
PULL
