The part integrates two independent comparators in one 8-SOIC package, saving board area versus two single-channel devices. ## Supply flexibility and output compatibility The TLC372CD operates from a single 3V to 16V supply or a dual ±1.5V to ±8V rail. This range lets it sit on a 5V logic bus, a 12V industrial rail, or a split ±5V analog supply without a separate regulator. The output stage supports CMOS, MOS, open-drain, and TTL levels, so it can drive a microcontroller GPIO, a logic gate input, or a pull-up resistor network directly. Open-drain mode is especially useful for wired-OR or level-shifting applications where the output high voltage differs from the comparator supply. ## Low bias current for high-impedance sensing Input bias current is max 5 pA at 5V. That is orders of magnitude lower than a bipolar comparator—meaning negligible loading on a high-impedance source like a photodiode, pH probe, or precision resistor divider. The 5 mV max input offset voltage at 5V is adequate for general-purpose threshold detection but not for microvolt-level sensing; for tighter offset, the TLV9032 family (1.5 mV typical) is a closer fit. ## Quiescent current and thermal envelope Max quiescent current is 400 µA for both comparators combined. That keeps self-heating minimal in the 8-SOIC package and makes the part suitable for battery-powered or thermally constrained boards. Not rated for automotive under-hood or outdoor industrial enclosures. ## Active lifecycle—no supply chain pressure Texas Instruments lists the TLC372CD as Active. That means no last-time-buy window, no EOL notice, and full factory support for new designs. The part is ROHS3 compliant.","metaTitle":"TLC372CD LinCMOS Dual Differential Comparator, 3V-16V","metaDescription":"Texas Instruments TLC372CD dual differential comparator in 8-SOIC. 3V to 16V supply, 5pA input bias, 400µA quiescent, CMOS/TTL outputs.","metaKeywords":null},"attributes":{"series":"LinCMOS™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Type":"Differential","Series":"LinCMOS™","Package":"Tube","Output Type":"CMOS, MOS, Open-Drain, TTL","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Number of Elements":"2","Operating Temperature":"0°C ~ 70°C","Current - Output (Typ)":"20mA","Supplier Device Package":"8-SOIC","Current - Quiescent (Max)":"400µA","Current - Input Bias (Max)":"5pA @ 5V","Voltage - Input Offset (Max)":"5mV @ 5V","Voltage - Supply, Single/Dual (±)":"3V ~ 16V, ±1.5V ~ 8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.42","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.42000","currency":"USD"},{"qty":10,"price":"$1.27300","currency":"USD"},{"qty":25,"price":"$1.20800","currency":"USD"},{"qty":100,"price":"$0.99230","currency":"USD"},{"qty":250,"price":"$0.92756","currency":"USD"},{"qty":500,"price":"$0.81970","currency":"USD"},{"qty":1000,"price":"$0.64713","currency":"USD"},{"qty":2500,"price":"$0.61050","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/c67582ed472de68028de2fe24e6da24c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the equivalent or cross reference for TLC372CD?","answer":"However, the TLV9032DDFR uses a different package (SOT-23-8) and supply range (1.65V min), so a board respin is required."},{"question":"Can I use TLC372CD as a replacement for a failed dual comparator?","answer":"Yes, provided the original part is a dual comparator in an 8-SOIC footprint and operates within 3V to 16V single or ±1.5V to ±8V dual supply.
