74VHCT245A, OCTAL BUS TRANSCEIVER

The 74VHCT245A is an advanced high-speed CMOS OCTAL BUS TRANSCEIVER (3-STATE) fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology.

This IC is intended for two-way asynchronous communication between data busses; the direction of data trasmission is determined by the
