Download the P4C149 datasheet PDF.
This datasheet also covers the P4C148 variant, as both devices belong to the same ultra high speed 1k x 4 static cmos rams family and are provided as variant models within a single manufacturer datasheet.
General Description
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.
Key Features
Full CMOS, 6T Cell High Speed (Equal Access and Cycle Times).
10/12/15/20/25/35/45/55 ns (Commercial).
15/20/25/35/45/55 ns
Low Power Operation
Single 5V ± 10% Power Supply.

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 fast chip select capability using CS. The CMOS memories require no clocks or refreshing, and have equal access and cycle times. Inputs are fully TTL-compatible. The RAMs operate fr
