Quad comparator for slow threshold and zero-crossing detection
It packs four independent comparators into a single 14-pin DIP, each capable of sinking or sourcing 20 mA to drive CMOS, push-pull, or TTL logic directly. Propagation delay sits at 4.5 µs — not for high-speed switching, but plenty for temperature thresholds, over-voltage locks, or zero-crossing detect in power supplies and motor drives. The 84 dB CMRR keeps common-mode noise from tripping false edges on long sensor runs.
Supply range and quiescent draw
Single-supply operation from 3 V to 16 V, or split supplies within the same total range. Quiescent current maxes at 100 µA per package.
This limits the TLC3704CN to indoor, conditioned environments — office equipment, appliance control boards, benchtop instrumentation, or telecom racks with climate control. Not suited for engine bays, outdoor enclosures, or unheated factory floors without additional thermal management.
14-lead PDIP (0.300" body width, 7.62 mm pitch) with through-hole mounting. Ships in tube.
Active lifecycle status per the manufacturer. No last-time-buy or NRND flags. ROHS3 compliant. The TLC3704CN remains a stable line item for BOM freeze — no imminent obsolescence risk.
