  • The TS3021 single comparator features high-speed response time with rail-to-rail inputs. With a supply voltage specified from 2 to 5 V, this comparator can operate over a wide temperature range: -40 °C to 125 °C.

    The TS3021 comparator offers micropower consumption as low as a few tens of microamperes thus providing an excellent ratio of power consumption current versus response time.
    The TS3021 includes push-pull outputs and is available in small packages (SOT23-5 and SC70-5).

    Key Features

    • Propagation delay: 38 ns
    • Low current consumption: 73 µA
    • Rail-to-rail inputs
    • Push-pull outputs
    • Supply operation from 1.8 to 5 V
    • Wide temperature range: -40 °C to 125 °C
    • High ESD tolerance: 5 kV HBM, 300 V MM
    • Latch-up immunity: 200 mA
    • SMD packages
    • Automotive qualification
