DESCRIPTION
The P4C1298/L are 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 ntegrity s maintained for supply voltages down
to 2.0V. Current drain is typically 10 μA from a 2.0V supply.

ULTRA HIGH SPEED 64K x 4
STATIC CMOS RAM
Access times as fast as 15 nanoseconds are available,
permitting greatly enhanced system speeds. CMOS is
utilized to reduce power consumption.
The P4C1298 is available in a 28-pin 300 mil DIP or SOJ, as
well as a 28-pin 350x500 mil LCC package, providing
excellent board level densities.
