DESCRIPTION
TheM54/74HC7245 HC7640,HC7643 andHC7645
utilise silicon gate C
2
MOS technology to achive
operating speeds equivalent to LSTTL devices.
Along with the low power dissipation and high noise
immunity of standads C
2
MOS integrated circuit, it
possesses the capability to drive 15 LSTTL loads.
These IC’s are intended for two-way asynchronous
communication between data buses, and the
direction of data trasmission is determined by DIR
input.Theenableinput(G)canbeusedtodisablethe
device so that the buses are effectively isolated.
The HC7245/640/7643/7645 have the same pin
configuration and function as the HC245/640/643
and they have a hysteresis characteristics with each
input, so HC7245/7640/7643/7645 can beusedas a
line receiver, etc. All input are equipped with
protection circuits against static discharge and
transient excess voltage.

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
PULLDOWN ORPULL UP RESISTOR.
