DESCRIPTION
The P4C188 and P4C188L are 65,536-bit ultra high speed
static RAMs organized as 16K x 4. The CMOS memories
require no clocks or refreshing and have equal access and
cycle times. Inputs and outputs are fully TTL-compatible.
The RAMs operate from a single 5V±10% tolerance power
supply. With battery backup, data integrity is maintained for
supply voltages down to 2.0V. Current drain is typically 10
µA from a 2.0V supply.
Access times as fast as 10 nanoseconds are available,
permitting greatly enhanced system speeds. CMOS is
utilized to reduce power consumption to a low 715mW
active, 193mW standby and only 5mW in the P4C188L
version.
The P4C188 and P4C188L are available in 22-pin 300 mil
DIP, 24-pin 300 mil SOJ and 22-pin LCC packages provid-
ing excellent board level densities.
