MB7128H - HiGH SPEED SCHOTTKY TTL PROM

Download the MB7128H datasheet PDF. This datasheet also covers the MB7127E variant, as both devices belong to the same high speed schottky ttl prom family and are provided as variant models within a single manufacturer datasheet.

Description

The Fujitsu MB7127/MB7128 are high speed Schottky TTL electrically field programmable read only memories.

With open collector outputs on the MB7127 and three-state outputs on the MB7128, memory expansion is simple.

The memory is fabricated with all logic "zeros" (positive logic).

Features

  • Organization: 2048 words by 4-bits.
  • TTL compatible input/output.
  • Fast access time: M B7127E1M B7128E: 55 ns Max. 30 ns Typ. MB7127H/MB7128H: 45 ns Max. 30 ns Max.
  • Low Power Dissipation: 155 mA Max.
  • Single +5V supply voltage.
  • Proven high programmability and reliability of DEApTM (Diffused Eutectic Aluminum Process).
  • Simplified and lower power programming.
  • Low current PNP inputs.
  • MB7127: Open collector outputs.

FUJITSU MICROELECTRONICS HIGH SPEED SCHOTTKY TrL 8192·BIT PROM DESCRIPTION The Fujitsu MB7127/MB7128 are high speed Schottky TTL electrically field programmable read only memories. With open collector outputs on the MB7127 and three-state outputs on the MB7128, memory expansion is simple. The memory is fabricated with all logic "zeros" (positive logic). Logic level "ones" can be pro- grammed by the highly reliable DEApTM (Diffused Eutetic Aluminum Process) during a simple programming procedure. The sophisticated Schottky TTL process enables small chip size and fast access time. The extra test cells and unique testing methods provide extremely high programmability.
