MB7121E - HiGH SPEED SCHOTTKY TTL PROM

Description

The Fujitsu MB7121 and MB7122 are high speed Schottky TTL electrically field programmable read only memories.

With open collector outputs on the MB7121 and three-state outputs on the MB7122, memory expansion is simple.

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