The P4C168, P4C169 and P4C170 are a family of 16,384bit 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 eliminate data bus contention. The RAMs operate from a single 5V 10% tolerance power supply.
