DESCRIPTION

The P4C422 is a 1,024-bit high-speed (10ns) Static

RAM with a 256 x 4 organization. The memory requires

no clocks or refreshing and has equal access and cycle

times. Inputs and outputs are fully TTL compatible.

Operation is from a single 5 Volt supply. Easy memory

expansion is provided by an active LOW chip select one

(CS1) and active HIGH chip select two (CS2) as well as

3-state outputs.

In addition to high performance and high density, the

device features latch-up protection, single event and

upset protection. The P4C422 is offered in several

packages: 22-pin 400 mil DIP (plastic and ceramic), 24-

pin 300 mil SOIC, 24-pin square LCC and 24-pin

CERPACK. Devices are offered in both commercial and

military temperature ranges.
