No NRND or LTB flags. ## Wide supply, flexible output — what the ratings mean Runs on a single supply from 2V to 36V, or split supplies ±1V to ±18V. The 700µA max quiescent current is modest; not the lowest-power option for battery gear, but fine for a motor drive or PLC input module where the comparator is always on. Output type is CMOS, MOS, open-collector, or TTL — the pull-up voltage can be independent of the comparator supply, so level-shifting to a 1.8V or 3.3V logic input is straightforward. The 20mA typical output drive is enough to switch a small relay or LED directly, though for a logic input the sink current is usually under a milliamp. Input offset voltage max is 5mV at 30V, and input bias current max is 0.25µA at 5V. For a general-purpose differential comparator these are standard numbers — adequate for overvoltage detection, zero-crossing, or threshold sensing. If the design needs sub-millivolt precision, look at a precision comparator family instead. ## Temperature range and package — fits industrial boards The SOT-23-5 package (SC-74A, SOT-753) is a 5-pin surface-mount footprint, 2.9mm x 1.6mm typical. Single-element comparator in a tiny package; good for dense PCBs where board area is tight.","metaTitle":"TL331KDBVT Differential Comparator, SOT-23-5, Active","metaDescription":"Single differential comparator in SOT-23-5.

For a single-channel replacement, the TL331KDBVT shares a similar supply range (2V to 36V, LM393 is 2V to 36V) and output type (open-collector). Pinout differs — verify the board layout. The SOT-23-5 package is much smaller than the LM393's SOIC-8 or DIP-8, so mechanical fit must be checked."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TL331KDBVT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TL331KDBVT when reusing this data.
