This class of device is a workhorse in threshold detection, zero-crossing detectors, window comparators, and oscillator circuits across industrial control, power-supply monitoring, and signal-conditioning boards. The TL393ID is listed as RoHS non-compliant. If your BOM requires lead-free soldering per EU RoHS or similar regulations, this part does not meet that requirement. It is suitable for legacy or exempted assemblies where tin-lead solder is still permitted, or for repair and replacement in existing equipment that was originally built with leaded components. Check your reflow profile and material declaration before committing the line. No need to qualify a substitute or worry about allocation-driven redesign.","metaTitle":"TL393ID Dual Comparator, Active, RoHS Non-Compliant","metaDescription":"Texas Instruments TL393ID dual comparator, active lifecycle status.

Both are dual comparators with open-collector outputs, and the pinout is the same across the standard SOIC-8 and DIP-8 footprints. The TL393ID is a direct drop-in replacement for the LM393 in most applications, though you should verify the input offset voltage and supply current specs against your design margin."},{"question":"What is the output configuration of TL393ID?","answer":"The TL393ID has open-collector outputs. This means the output can sink current but cannot source it; an external pull-up resistor to the desired logic voltage is required. This configuration allows the outputs to be wired-ORed and also makes the part compatible with various logic families (TTL, CMOS) by selecting the appropriate pull-up voltage."},{"question":"Is TL393ID compatible with 5V logic?","answer":"Yes, the TL393ID works directly with 5V logic. With an open-collector output and a pull-up resistor to 5V, the output swings from near ground to 5V, which is compatible with standard 5V TTL and CMOS logic inputs. The comparator itself can operate from a single supply as low as 2V and up to 36V, or from dual supplies, giving flexibility in mixed-voltage designs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TL393ID","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TL393ID when reusing this data.
