Product Description

Pericom Semiconductor’s AVC series of logic circuits are produced

using the Company’s advanced 0.35 micron CMOS technology,

achieving industry leading performance.

Pericom Semiconductor’s PI74AVC164245, a 16-bit (dual-octal)

noninverting bus transceiver, contains two separate supply rails:

B port (V

at 1.8-2.5V. This arrangement permits translation from a 1.8-2.5V to

3.3V environment and vice versa.

The PI74AVC164245 is designed for asynchronous communication

between data buses.

To ensure the high impedance state during power up or power

down, the output-enable (OE) input should be tied to V

a pullup resistor: the minimum value of the resistor is determined by

the current-sinking capability of the driver.
