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
