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.
