16-Bit Buffer Driver
with 3-STATE Outputs
PI74ALVCH162244
Product Description
Pericom Semiconductors PI74ALVCH series of logic circuits
are produced in the Companys 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 V
CC
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 V
CC
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
inputs last state whenever the data input goes to high-imped-
ance preventing floating inputs and eliminating the need for
pullup/down resistors.
