P4C148 - ULTRA HIGH SPEED 1K x 4 STATIC CMOS RAMS

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.

P4C148, P4C149 ULTRA HIGH SPEED 1K x 4 STATIC CMOS RAMS 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.
