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
(
CS
) and active HIGH chip select two (CS
2
) as well as
3-state outputs.

FUNCTIONAL BLOCK DIAGRAM
PIN CONFIGURATIONS
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.
