16-Bit Buffer Driver

with 3-STATE Outputs

PI74ALVCH162244

Product Description

Pericom Semiconductors PI74ALVCH series of logic circuits
are produced in the Companys advanced 0.5 micron CMOS
technology, achieving industry leading speed.

The PI74ALVCH162244 is an non-inverting 16-bit buffer/driver
designed for low voltage 2.3V to 3.6V VCC operation.

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
down, OE should be tied to VCC through a pullup resistor in
which the minimum value is determined by the current-sinking
capability of the driver.

The PI74ALVCH162244 has Bus Hold which retains the data
inputs last state whenever the data input goes to high-imped­ance preventing floating inputs and eliminating the need for
pullup/down resistors.

Product Features

• PI74ALVCH162244 is designed for low voltage operation

• V

CC

= 2.3V to 3.6V

• Hysteresis on all inputs

• Typical V

OLP

(Output Ground Bounce)

< 0.8V at VCC = 3.3V, TA = 25°C
