Texas Instruments SN54HCT189FH is a CMOS Standard SRAM with a memory organization of 16 words by 4 bits. This asynchronous memory component features a maximum access time of 27ns and operates across a temperature range of -55°C to +125°C. The output characteristics are 3-state, and it employs a parallel interface. The device is housed in a 20-terminal ceramic chip carrier (CQCC20) package with a terminal pitch of 1.270mm, conforming to JESD-30 code S-XQCC-N20. Typical applications for this component include industrial and defense systems requiring robust memory solutions. Its 5V nominal supply voltage and low supply current of 30mA maximum make it suitable for power-sensitive designs.
