It packs four independent comparators into a 14-TSSOP surface-mount package, each with CMOS/open-drain outputs. The 5pA typical input bias current at 5V makes it a natural fit for high-impedance sensor interfaces — pH probes, photodiode amplifiers, or precision threshold detectors where a bipolar comparator would load the source. Supply range spans 3V to 16V, single or dual, so it can sit on a 5V logic rail or a 12V industrial bus without a secondary regulator. ## 4.5 µs propagation delay — what it means for your loop Propagation delay is 4.5 µs max. Quiescent current is 125 µA max across all four comparators. ## Open-drain outputs — wired-OR and level translation The CMOS/open-drain output stage lets you pull up to any voltage within the supply range, independent of the comparator supply. That means a 5V-powered TLC339IPW can drive a 3.3V logic input through an external pull-up resistor, or sink up to 20 mA into a PLC digital input card. Multiple open-drain outputs can be wired-OR'd on a single pull-up to create a shared fault bus — one common trick in motor-drive and UPS fault-logic designs. ## 84 dB CMRR and 5 mV offset — real-world margin CMRR is 84 dB typical. Input offset voltage is 5 mV max at 10 V. ## Lifecycle and sourcing posture Lifecycle status is Active. ROHS3 compliant. TLV9032DDFR is a different comparator family.","metaTitle":"TLC339IPW LinCMOS Quad Comparator, 4.5µs, 14-TSSOP","metaDescription":"TI TLC339IPW quad general-purpose comparator. 4.5µs propagation delay, 5pA input bias, 3V–16V supply.
