The AD7574 is a low‑cost, 8‑bit successive‑approximation ADC that operates from a single +5 V supply. It can be interfaced like static RAM, ROM, or slow memory, making it suitable for avionics, instrumentation, and process‑automation applications.
The document provides a functional block diagram, pin configuration, ordering guide, detailed electrical specifications, timing diagrams for static‑RAM, ROM, and slow‑memory interface modes, as well as application hints such as clock oscillator usage and external clock operation.
