P4C149 Ultra High Speed 4K x 1 Static CMOS RAMS

The P4C148 and P4C149 are 4,096-bit ultra high-speed static RAMs organized as 1K x 4. Both devices have common input/output ports. The P4C148 enters the standby mode when the chip enable (CE) goes HIGH; with CMOS input levels, power consumption is extremely low in this mode. The P4C149 features a fa.
