DESCRIPTION

The P4C1681 and P4C1682 are 16,384-bit (4K x 4) ultra

high speed static RAMs similar to the P4C168, but with

separate data I/O pins. The P4C1681 features a

transparent write operation; the outputs of the P4C1682

are in high impedance during the write cycle. All devices

have low power standby modes. 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.

TheP4C1681andP4C1682areavailablein24-pin300mil

DIP, SOIC, Solder Seal Flatpack, and SOJ packages, as

well as a 28-pin LCC package, providing excellent board

level densities.
