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
CC
through a pull-up resistor; the
minimum value of the resistor is determined by the current sinking
ability of the driver.
