OUTPUT COMPARATOR
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.
