FEATURES
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
Full CMOS, 6T Cell
High Speed (Equal Access and Cycle Times)

PIN CONFIGURATIONS
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 and SOJ packages.
The P4C169 is also available in a 20-pin 300 mil SOIC
package. The P4C170 is also available in a 22-pin 300 mil
SOJ package.
