This page provides the datasheet information for the UPD2149-2, a member of the UPD2149 4096 (1024 x 4) BIT STATIC RAM family.

Datasheet Summary

Features

  • associated with non-clocked static memories. The JlPD2149 is encapsulated in an 18-pin ceramic package configured with the industry standard pinout. It is directly TTL compatible in all respects: inputs, outputs, and a single +5V supply. The data is read out non-destructively and has the same polarity as the input data. FEATU RES.
  • Completely Static Memory - No Clock or Timing Strobe Required.
  • Equal Access and Cycle Times, Faster Chip Select Access.
  • Single +5V Supply.
