DESCRIPTION
The P4C1281 and P4C1282 are 262,144-bit (64Kx4) ultra
high-speed static RAMs similar to the P4C1258, but with
separate data I/O pins. The P4C1281 features a transpar-
ent write operation; the outputs of the P4C1282 are in high
impedance during the write cycle. The RAMs operate from
a single 5V ± 10% tolerance power supply.
Access times as fast as 12 nanoseconds are available,
permitting greatly enhanced system operating speeds.
CMOS is used to reduce power consumption.
The P4C1281 and P4C1282 are available in 28-pin 300
mil DIP and SOJ, and a 28-pin 350x550 mil LCC providing
excellent board level densities.

P4C1281/P4C1282 - ULTRA HIGH SPEED 64K x 4 CMOS STATIC RAMS
TIMING WAVEFORM OF WRITE Cycle No. 1 (WE Controlled) (10, 11, 12)
Timing Waveform of Write Cycle No. 2 (CE Controlled) (10, 11, 12)
Notes:
10. CE and WE must be LOW for WRITE cycle.
11. If CE goes HIGH simultaneously with WE HIGH, the output remains
in a high impedance state
Document # SRAM136 REV OR
12. Write Cycle Time is measured from the last valid address to the first
transitioning address.
