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)  
controltoeliminatedatabuscontention.TheRAMsoper-  
ate 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.  
TheP4C168andP4C169areavailablein20-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.
