ProductDescription

Pericom Semiconductor’s PI74AVC+ series of logic circuits are

produced using the Company’s advanced submicron CMOS

technology, achieving industry leading speed.

PI74AVC+16244 is a noninverting 16-bit buffer/driver designed

The buffer/driver is designed specifically to improve both the

performance and density of 3-state memory address drivers, clock

drivers, and bus-oriented receivers and transmitters.

The device can be used as four 4-bit buffers, two 8-bit buffers, or

one 16-bit buffer. It provides inverting outputs and symmetrical

active-low output-enable (OE) inputs.

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

the minimum value is determined by the current-sinking capability

of the driver.
