74189 64-Bit Static RAM TTL IC – 16×4 Memory DIP-16

QAR 3.00/ unit

Description

The 74189 is a 64-bit static random access memory (SRAM) integrated circuit organized as 16 words × 4 bits. It provides fast asynchronous read and write operations, making it suitable for temporary data storage in digital systems. Built using TTL logic, the device operates on a standard 5V supply and offers tri-state outputs for direct bus interfacing. The 74189 is widely used in educational digital electronics, legacy computing systems, register storage, and small memory applications.
