DESCRIPTION

The UTC ULC831 is a push-pull output comparator, allowing operation from 1.4V-5.5V. It has the best-in-class power supply current versus propagation delay performance. It features as low as 6μs response time with 100mV overdrive at 1.4V, and it has an ultra low power supply current of 300nA (TYP). The UTC ULC831 series is ideally suited for RC timers, Window Detectors, IR Receivers, Multivibrators, Alarm and Monitoring Circuits. The UTC ULC831 is available in Green SOT-25 space-saving packages. It is rated over the -40°C to +85°C temperature range.
