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
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. 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 from a single 5V ± 10% tolerance power supply.
Two Options – P4C148 Low Power Standby Mode – P4C149 Fast Chip Select Control
Common Input/Output Ports
Three-State Outputs
Fully TTL Compatible Inputs and Outputs
Standard Pinout (JEDEC Approved) – 18 Pin 300 m...
