Stack the error budget: a 10 MΩ source sees only 50 µV of offset from bias current, negligible compared to the 5 mV input offset voltage. For precision threshold circuits, the offset itself sets the floor; the bias contribution is effectively zero. ## 400 µA quiescent — power budget for always-on comparators At 400 µA maximum quiescent for both comparators, the TLC372CPW is not the lowest-power option on the market, but it is well within the budget for a multi-channel monitor on a 12 V industrial rail. For battery-powered gear that spends most of its time asleep, the 400 µA figure means the comparator bank draws about 4.8 mW at 12 V — acceptable for a sensor node that wakes periodically, though a micropower comparator would stretch battery life further. ## 0°C to 70°C — indoor and office environments only The commercial temperature range limits the TLC372CPW to applications where the ambient stays between freezing and 70°C — office equipment, appliances, indoor instrumentation, and benchtop gear. It is not rated for automotive under-hood, outdoor telecom cabinets, or factory-floor enclosures without active cooling. If the design lives in a conditioned space, the 0°C to 70°C window is fine; for anything harsher, look at the industrial-grade siblings in the LinCMOS family. ## 8-TSSOP footprint and surface-mount assembly Housed in an 8-TSSOP package with a 4.40 mm body width and 0.65 mm pin pitch, the TLC372CPW is a straightforward surface-mount part for standard reflow profiles. The supplier device package is 8-TSSOP, and the mounting type is surface mount. No thermal pad or special footprint is required — a basic land pattern matching the 8-TSSOP outline is sufficient. The part ships in tube, so plan for tube-to-reel transfer if your pick-and-place line expects tape-and-reel input. ## Active lifecycle and compliance It is ROHS3 compliant, which covers the current EU RoHS exemption list. For new designs, the active status means no imminent obsolescence risk.","metaTitle":"TLC372CPW LinCMOS Differential Comparator, 8-TSSOP, 0–70°C","metaDescription":"TLC372CPW dual differential comparator from TI's LinCMOS series. 5 pA input bias, 400 µA quiescent, 3–16 V supply. 8-TSSOP. 0°C to 70°C.

The TLC372CPW offers dramatically lower input bias — critical for high-impedance sources — but its output is not the same open-collector as the LM393; the TLC372CPW supports CMOS, MOS, open-drain, and TTL outputs. Pin compatibility depends on the specific LM393 package variant; verify the pinout against your PCB layout before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TLC372CPW","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TLC372CPW when reusing this data.
