MB7142E - High Speed Schottky TTL PROM

This page provides the datasheet information for the MB7142E, a member of the MB7141E High Speed Schottky TTL PROM family.

Description

The Fujitsu MB7141 and MB7142 are high speed electrically field programmable read only memories.

With open collector outputs on the MB7141 and three-state outputs on the MB7142.

memory expansion is simple.

Features

  • Organization: 4096 words x 8 bits, fully decoded.
  • TTL compatible Input/output.
  • Fast Access Time: MB7141E1MB7142E: 65 ns Max. 45 ns Typ_ MB7141 H/MB7142H: 55 ns Max. 45 ns Typ_ The sophisticated passive isolation termed lOP (Isolation by Oxide and Polysilicon) with thin epitaxial layer and schottky TTL process permits minimal chip size and fast access time. The extra test cell and unique testing methods provide enhanced correlation between programmed and unprogrammed.

FUJITSU MICROELECTRONICS lUGH SPEEI] SCHOTTKY TTL 32,768·BIT PROM MB7141E/H MB7142E/H DESCRIPTION The Fujitsu MB7141 and MB7142 are high speed electrically field programmable read only memories. With open collector outputs on the MB7141 and three-state outputs on the MB7142. memory expansion is simple. The memory is fabricated with all logic "zeros" (positive logic). Logic level "ones" can be programmed by the highly reliable DEApTM (Diffused Eutectic Aluminum Process) during a simple programming procedure. FEATURES • Organization: 4096 words x 8 bits, fully decoded • TTL compatible Input/output • Fast Access Time: MB7141E1MB7142E: 65 ns Max. 45 ns Typ_ MB7141 H/MB7142H: 55 ns Max.
