This document describes the features of IDT7132SA/LA and IDT7142SA/LA high-speed 2K x 8 dual-port static RAM. The product features high-speed access, low-power operation, expandable data bus width, port arbitration logic, BUSY output flag, battery backup operation, TTL compatibility, etc.
The IDT7132SA/LA (MASTER) and IDT7142SA/LA (SLAVE) are high‑speed 2 K × 8 dual‑port static RAMs offered in commercial, industrial and military temperature ranges. They provide two independent ports with separate address, control and I/O pins, allowing asynchronous read/write access and optional battery‑backed data retention for the LA versions.
The document includes functional block diagrams, pin‑out tables, absolute‑maximum ratings, DC and AC electrical characteristics, timing diagrams, busy‑logic operation, and package options. Key specifications such as supply voltage, input thresholds, power consumption and data‑retention requirements are listed in detailed tables.
