Description

The TS3021, TS3021A 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, TS3021A 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, TS3021A includes push-pull outputs and is available in small packages

(SOT23-5 and SC70-5).
