PI74AVC+16245

2.5V 16-Bit Bidirectional Transceiver

with 3-State Outputs

Product Features

ProductDescription

PI74AVC+16245 is designed for low voltage operation,

Pericom Semiconductors PI74AVC+ series of logic circuits are

produced using the Companys advanced submicron CMOS

technology, achieving industry leading speed.

= 1.65V to 3.6V

True ±24mA Balanced Drive @ 3.3V

ThePI74AVC+16245isa16-bitbidirectionaltransceiverdesigned

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

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.

Compatible with Philips and T.I.AVC Logic family

supports partial power-down operation

OFF

3.6V I/O Tolerant inputs and outputs

All outputs contain a patented DDC

(Dynamic Drive Control) circuit that reduces noise

without degrading propagation delay

Industrial operation at 40°C to +85°C

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

Available Packages:

48-pin 240-mil wide plastic TSSOP

48-pin 173-mil wide plastic TVSOP

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.
