DESCRIPTION

The ULC8740 is a single high-speed comparator optimized for

systems powered from a 3V or 5V supply. The device features

high-speed response, low-power consumption, and rail-to-rail input

range. Propagation delay is 45ns, while supply current is only 200μA.

The UTC ULC8740 supports rail-to-rail input and output operation.

The input common mode voltage range is from -0.1V to (+VS) +

0.1V, and the output voltage swing is within 0.3V of the rails without

external pull-up or pull-down resistor. The device can be compatible

with CMOS and TTL logics. Any input or output pin has a continuous

short-circuit protection to both power supply rails.

The UTC ULC8740 has an internal hysteresis for reducing

comparator sensitivity to noise, even when the input signals move slowly.
