DESCRIPTION

The P4C168, P4C169 and P4C170 are a family of

16,384-bit ultra high-speed static RAMs organized as 4K

x 4. All three devices have common input/output ports.The

P4C168 enters the standby mode when the chip enable

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

consumption is only 83mW in this mode. Both the P4C169

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.

Access times as fast as 12 nanoseconds are available,

permitting greatly enhanced system operating speeds.

CMOS is used to reduce power consumption to a low 715

mW active, 193 mW standby.

The P4C168 and P4C169 are available in 20-pin (P4C170

in 22-pin) 300 mil DIP packages providing excellent

board level densities. The P4C168 is also available in 20-

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

packages.

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

package.
