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.
