UPD2149 - 4096 (1024 x 4) BIT STATIC RAM

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.

NEe Microcomputers, Inc. NEe JJ. PD2149 JJ. PD2149-1 po PD2149-2 ~rn~[~~~~illrnW 4096 (1024x4) BIT STATIC RAM DESCR IPTION The JlPD2149 is a 4096-bit static Random Access Memory organized as 1024 words bv 4-bits. Using a scaled NMOS technology, it incorporates an innovative design approach which provides the ease-of-use 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.
