Comparator with a voltage reference — why you reach for this part
The 50 mV of internal hysteresis keeps the output clean near the trip point without adding positive feedback resistors.
Supply range and output — fits 3V and 5V logic rails
The supply range spans 2.5 V to 11 V single supply, or ±1.25 V to ±5.5 V with dual supplies. The output is CMOS/TTL compatible, so it drives logic inputs directly without a pull-up to a different rail. Propagation delay is 12 µs max — fine for DC threshold monitoring and slow-changing signals, not for high-speed comparator applications.
Package and temperature grade — board-fit details
Input offset voltage is 10 mV max at 5 V; CMRR and PSRR are both 80 dB typical, giving reasonable rejection of supply and common-mode variations for a low-power comparator.
