MB7128H - HiGH SPEED SCHOTTKY TTL PROM

This page provides the datasheet information for the MB7128H, a member of the MB7127E HiGH SPEED SCHOTTKY TTL PROM family.

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).

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.
