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.

Notes:
9. CE and WE must be LOW for WRITE cycle.
10. If CE goes HIGH simultaneously with WE high, the output remains
in a high impedance state.
11. Write Cycle Time is measured from the last valid address to the first
transition address.
12. Transition is measured ±200mV from steady state voltage prior to
change with specified loading in Figure 1. This parameter is
sampled and not 100% tested.
