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鹵10% tolerance power supply.
With battery backup, data integrity is maintained with
supply voltages down to 2.0V. Current drain is typically 10
碌A(chǔ)
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.
