The document describes the LM393 voltage comparator product from TCI, including its features and applications.
The LM393 voltage comparator from TAITRON consists of two independent comparators designed for single‑supply operation from 2 V to 36 V. It offers low supply current (0.8 mA typical), low input bias (25 nA typical) and output compatible with TTL, DTL and CMOS logic.
The device is offered in DIP‑8, SOP‑8 and TSSOP‑8 packages and includes detailed absolute‑maximum ratings, electrical characteristics and typical performance curves such as supply current, output saturation voltage and large‑signal gain.
