Texas Instruments SNC54LS189J is a 64-bit (16 words x 4 bits) synchronous static random-access memory (SRAM) device from the SNC54LS189 series. Featuring a maximum access time of 90ns, this component operates with TTL technology and offers 3-state outputs for flexible bus interfacing. The device is configured in a 16x4 memory organization and is housed in a 16-pin ceramic dual in-line package (CDIP16) with through-hole termination. Designed for demanding applications, it supports an operating temperature range of -55°C to +125°C and operates from a nominal supply voltage of 5V (4.5V to 5.5V). This memory component finds application in aerospace, defense, and industrial control systems requiring high reliability and performance. The screening level adheres to MIL-STD-883 Class B (Modified).
