The Advanced Micro Devices AM27LS191ALC-S is a 2048-bit (512 x 4) bipolar, one-time programmable (OTP) ROM. This asynchronous memory device features a maximum access time of 30ns and operates from a 4.75V to 5.25V supply. The output is 3-state, enabling bus contention avoidance. Packaged in a 28-lead ceramic quad flat chip carrier (CQCC), it is suitable for surface mounting. This component finds application in industrial control systems, telecommunications infrastructure, and legacy system upgrades requiring reliable, non-volatile program storage. The AM27LS191 series is known for its robust performance characteristics in demanding environments.
