Features (Note 1) (Note 2)
The TC74ACT245 and 640 are advanced high speed CMOS
They achieve the high speed operation similar to equivalent
These devices may be used as a level converter for interfacing
They are intended for two-way asynchronous communication
The enable input ( G ) can be used to disable the device so that
All inputs are equipped with protection circuits against static

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
