DESCRIPTION
The P4C148 and P4C149 are 4,096-bit ultra high-speed
static RAMs organized as 1K x 4. Both devices have
common input/output ports. The P4C148 enters the
standby mode when the chip enable (
CE
) goes HIGH;
with CMOS input levels, power consumption is extremely
low in this mode. The P4C149 features a fast chip select
capability using
CS
. 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.

FUNCTIONAL BLOCK DIAGRAM
PIN CONFIGURATION
Access times as fast as 10 nanoseconds are available,
permitting greatly enhanced system operating speeds.
CMOS is used to reduce power consumption when
active; for the P4C148, consumption is further reduced in
the standby mode.
The P4C148 and P4C149 are available in 18-pin 300 mil
DIP packages, as well as 2 different LCC packages,
providing excellent board level densities.
