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+16344 is a 1-bit to 4-bit buffer/driver designed for

1.65V to 3.6V V

CC

operation.

The address/driver is designed for applications where four separate

memory locations must be addressed by a single address.

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

down, OE should be tied to V

CC

through a pullup resistor; the

minimum value of the resistor is determined by the current sinking

capability of the driver.
