DESCRIPTION

The P4C1258 is a 262,144-bit ultra high speed static RAM

organized as 64K x 4. The CMOS memory requires no clock

or refreshing and has equal access and cycle times. Inputs

and outputs are fully TTL-compatible. The RAM operates

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.

Three-State Outputs

TTL/CMOS Compatible Outputs

Fully TTL Compatible Inputs

Standard Pinout (JEDEC Approved)

– 24-Pin 300 mil DIP, SOJ

FEATURES
