P4C149 - Ultra High Speed 4K x 1 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 ns (Commercial).
  • 15/20/25/35 ns (P4C148 Military) Low Power Operation.
  • 715 mW Active.
  • 10 (Commecial).
  • 550 mW Active.
  • 25 (Commercial).
  • 110 mW Standby (TTL Input) P4C148.
  • 55 mW Standby (CMOS Input) P4C148 Single 5V ± 10% Power Supply P4C148/P4C149 Two Options.
  • P4C148 Low Power Standby Mode.
  • P4C149 Fast Chip Select Control Common Inpu.
