DESCRIPTION
The P4C167/L are 16,384-bit high speed static RAMs or-
ganized as 16K x 1. The CMOS memories require no clocks
or refreshing and have equal access and cycle times. The
RAMs operate from a single 5V ± 10% tolerance power
supply. Data integrity is maintained for supply voltages
down to 2.0V, typically drawing 10µA.
Access times as fast as 10 nanoseconds are available,
greatly enhancing system speeds. CMOS reduces power
consumption to low levels.
The P4C167/L are available in 20-pin 300 mil DIP, 20-pin
300 mil SOJ, and 20-pin LCC packages providing excel-
lent board level densities.

TIMING WAVEFORM OF WRITE CYCLE NO. 1 (WE CONTROLLED)(9)
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.
