The TC74VHC245 is an advanced high speed CMOS OCTAL
BUS TRANSCEIVER fabricated with silicon gate C²MOS
technology.
It achieves the high speed operation similar to equivalent
Bipolar Schottky TTL while maintaining the CMOS low
power dissipation.
It is 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.
