DESCRIPTION

The P4C164 and P4C164L are 65,536-bit ultra high-speed

static RAMs organized as 8K x 8. The CMOS memories

require no clocks or refreshing and have equal access and

cycle times. Inputs are fully TTL-compatible. The RAMs

operate from a single 5V±10% tolerance power supply.

With battery backup, data integrity is maintained with

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 operating speeds. In

full standby mode with CMOS inputs, power consumption

is only 5.5 mW for the P4C164L.

The P4C164 and P4C164L are available in 28-pin 300 mil

DIP and SOJ, 28-pin 600 mil ceramic DIP, and 28-pin 350

x 550 mil LCC packages providing excellent board level

densities.
