Texas Instruments SN74HC189 is a 16-word by 4-bit asynchronous CMOS standard Static Random Access Memory (SRAM) device. This component features a maximum access time of 81ns and operates across a temperature range of -40°C to +85°C. The SN74HC189 utilizes 3-state outputs for flexible bus interfacing. Its organization is 16 words x 4 bits, providing 64 bits of storage. This device is housed in a 16-pin Plastic Dual In-line Package (PDIP) with through-hole termination and a terminal pitch of 2.54mm. Applications for this memory component can be found in various industrial and consumer electronics systems requiring small-capacity, fast-access data storage.
