Quad differential comparator with 5 pA input bias
Its 5 pA typical input bias current at 5 V is the standout spec — orders of magnitude lower than a bipolar LM339 — making it the natural choice for high-impedance sensor interfaces, photodiode threshold detection, and battery-monitoring circuits where the source impedance cannot tolerate microamp-level loading.
Supply rails and output flexibility
The TLC374CNS runs from a single supply of 3 V to 16 V, or split supplies of ±1.5 V to ±8 V. That single-supply floor down to 3 V means it works directly off a 3.3 V rail without a secondary regulator. The output stage is configurable as CMOS, MOS, open-drain, or TTL — the open-drain option lets you wire-OR multiple comparator outputs and pull them to a different logic voltage than the comparator supply, which is useful for level-shifting into a 1.8 V or 5 V logic input.
Commercial temperature grade — indoor use
If the BOM calls for extended temperature, the TLC374CNS is the wrong tier; look at the TLC374M or TLC374Q variants in the same family for industrial or automotive grades.
This part can be designed into new production BOMs with confidence that the supply channel will remain open for the foreseeable future. ROHS3 compliant per the listing.
