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
