The P4C168, P4C169 and P4C170 are a family of

16,384-bitultrahigh-speedstaticRAMsorganizedas4K

x4. Allthreedeviceshavecommoninput/outputports.The

P4C168 enters the standby mode when the chip enable

(CE) control goes HIGH; with CMOS input levels, power

consumptionisonly83mWinthismode.BoththeP4C169

and the P4C170 offer a fast chip select access time that

is only 67% of the address access time. In addition, the

P4C170 includes an output enable (OE) control to elimi-

nate data bus contention. The RAMs operate from a

single 5V ± 10% tolerance power supply.

TheP4C168andP4C169areavailablein20-pin(P4C170

in 22-pin) 300 mil DIP packages providing excellent

boardleveldensities. TheP4C168isalsoavailablein20-

pin 300 mil SOIC, SOJ, CERPACK, and Flat Pack

packages.

The P4C169 is also available in a 20-pin 300 mil SOIC

package.
