P4C422
FEATURES
High Speed (Equal Access and Cycle Times)
– 10/12/15/20/25/35 ns (Commercial)
– 15/20/25 /35 ns (Military)
CMOS for Low Power
– 495 mW Max. – 10/12/15/20/25 (Commercial)
– 495 mW Max. – 15/20/25/35 (Military)
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 very high performance and very high den-
sity, 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 LCC and 24-pin CERPACK.
Devices are offered in both commercial and military
temperature ranges.
