Product Description

Pericom Semiconductor聮s PI74AVC+ series of logic circuits are

produced using the Company聮s advanced submicron CMOS

technology, achieving industry leading speed.

The PI74AVC+16245 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.

To ensure the high-impedance state during power up or power

down, OE should be tied to V

through a pull-up resistor; the

minimum value of the resistor is determined by the current sinking

ability of the driver.
