DESCRIPTION  
TheM54/74HC7245 HC7640, HC7643 and HC7645  
utilise silicon gate C2MOS technology to achive  
operating speeds equivalent to LSTTL devices.  
Along with the low power dissipation and high noise  
immunity of standads C2MOS 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)canbeused todisable the  
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 be used as a  
line receiver, etc. All input are equipped with  
protection circuits against static discharge and  
transient excess voltage.  
IT IS PROHIBITEDTOAPPLY A SIGNAL TOA 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 DOWN OR PULL UP RESISTOR.
