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 12 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.
