70 dB CMRR, 80 dB PSRR — noise rejection in mixed-signal boards
Typical CMRR of 70 dB and PSRR of 80 dB give this comparator decent rejection of common-mode and supply-borne noise. In a motor-drive or switching-regulator environment where the analog supply bounces, the 80 dB PSRR helps keep the trip point stable. Input offset voltage maxes at 15 mV at 5 V — adequate for level-shifting and window comparators but not precision sensing below a few millivolts.
No NRND or EOL notice is on record. For dual-sourcing flexibility, the TS393CDT is a two-channel open-drain comparator in a similar SOT-23-5 footprint, though it runs on a narrower 2.7 V supply and has a 0°C to 70°C temperature range — not a pin-for-pin drop-in for the single-channel TS7221BILT.
