Product Description
Pericom Semiconductor鈥檚 PI74ALVCH series of logic circuits
are produced using the Company鈥檚 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 non-inverting outputs and symmetri-
cal 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 鈥淏us Hold鈥?which retains the data
input鈥檚 last state whenever the data input goes to high-impedance
preventing 鈥渇loating鈥?inputs and eliminating the need for pullup/
down resistors.
