It compares two analog voltages per channel and outputs a logic-level signal via its open-drain MOS output stage. With a 4.5 µs propagation delay and 5 pA typical input bias current, it suits slow-to-moderate-speed threshold detection, zero-crossing detectors, window comparators, and sensor interface circuits where the input signal must not be loaded. The industrial temperature range (-40°C to 85°C) qualifies it for factory-floor sensor panels, outdoor telecom line cards, and HVAC controller boards. ## Low power draw and high input impedance Quiescent current maxes at 65 µA for both comparators, making this part a fit for loop-powered transmitters and battery-backed alarm circuits where every microamp counts. The 5 pA input bias at 5 V means the comparator presents essentially no load to a high-impedance source — think pH probe buffers, photodiode current thresholds, or resistive divider references that cannot tolerate a few nanoamps of leakage.","metaTitle":"TLC393IP LinCMOS Dual Comparator, 4.5 µs, 8-DIP","metaDescription":"TI TLC393IP general-purpose dual comparator. 65 µA quiescent, 5 pA input bias, 4.5 µs propagation delay.

The TLC393IP draws 65 µA total quiescent and has 5 pA input bias — a clear advantage for battery-powered or high-impedance sensor circuits. Both are dual comparators in 8-DIP with open-collector/open-drain outputs, but the TLC393IP's CMOS inputs preserve signal integrity where the LM393N would load the source."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TLC393IP","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TLC393IP when reusing this data.
