Product Description
Pericom Semiconductor’s PI74LCX series of logic circuits are
produced in the Company’s advanced 0.6 micron CMOS technology,
achieving industry leading speed grades.
The PI74LCX16245 is a 16-bit bidirectional transceiver designed for
asynchronous two-way communication between data buses. The
direction control input pin (xDIR) determines the direction of data
flow through the bidirectional transceiver. The Direction and Output
Enable controls are designed to operate this device as either two
independent 8-bit transceivers or one 16-bit transceiver. The output
enable (OE) input, when HIGH, disables both A and B ports by
placing them in HIGH Z condition.
The PI74LCX16245 can be driven from either 3.3V or 5.0V devices
allowing this device to be used as a translator in a mixed
3.3/5.0V system.
