PD2149 JJ.

Key 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.
