Dual differential comparator with LinCMOS input stage
Its differential input stage (type: Differential) gives it the common-mode rejection needed for precision threshold detection, zero-crossing, and window comparator circuits. 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.
