DESCRIPTION
The P4C164LL is a 64K density low power CMOS static
RAM organized as 8Kx8. The CMOS memory requires
no clocks or refreshing, and has equal access and cycle
times. Inputs are fully TTL-compatible. The RAM operates
from a single 5V±10% tolerance power supply.
Access times of 80 and 100 ns are available for commercial
and industrial temperatures; access times of 90 and 100
ns are available for military temperature. CMOS is utilized
to reduce power consumption to a low level.
The P4C164LL device provides asynchronous operation
with matching access and cycle times.
