The TC74AC245, 640 are advanced high speed CMOS OCTAL  
BUS TRANSCEIVERs fabricated with silicon gate and double-layer  
metal wiring C2MOS technology.  
They achieve the high speed operation similar to equivalent  
Bipolar Schottky TTL while maintaining the CMOS low power  
dissipation.  
They are intended for two-way asynchronous communication  
between data busses. The direction of data transmission is  
determined by the level of the DIR input.  
The enable input ( G ) can be used to disable the device so that  
the busses are effectively isolated.  
All inputs are equipped with protection circuits against static  
discharge or transient excess voltage.

Pin and function compatible with 74F245/640  
Note 1: Do not apply a signal to any bus terminal when it is in  
the output mode. Damage may result.  
Note 2: All floating (high impedance) bus terminals must have their input levels fixed by means of pull up or pull  
down resistors.
