82S25 - 64-BIT BIPOLAR SCRATCH PAD MEMORY

Datasheet Summary

Description

The 82S25 is a 64-bit, Schottky clamped TTL, ReadWrite Random Access Memory ideal for use in scratch pad and high-speed buffer memory applications.

The 82S25 is a fu lIy decoded memory array organ ized as 16 words of 4 bits each, with separate input and output lines.

Features

  • PNP inputs, one chip enable line, and open collector outputs for ease of memory expansion. The outputs of the 82S25 assume a logic "1" state during write. This allows both memory inputs and outputs to share a common bus for minimizing interconnections, and more effective utilization of common I/O circuitry. The 82S25 is available in the commercial and military temperature ranges. For the commercial temperature range (DOC to +75°C) specify N82S25, B or F. For the military temperature range (-55°C.
