DESCRIPTION
The P4C164 is a 65,536-bit ultra high-speed static RAM organized as 8K x 8. The CMOS memory requires no clocks or refreshing and has equal access and cycle times. Inputs are fully TTL-compatible. The RAM operates 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 8 nanoseconds are available, permitting greatly enhanced system operating speeds. The P4C164 is available in 28-pin 300 mil DIP and SOJ, 28-pin 600 mil plastic and ceramic DIP, 28-pin 350 x 550 mil LCC, 32-pin 450 x 550 mil LCC, and 28-pin CERPACK. The 70ns and 100ns P4C164s are available in the 600 mil plastic DIP.
