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.
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 providing excellent board level densities.
