LM393P is a Texas Instruments dual differential voltage comparator in 8-pin PDIP, tube packaging — open-collector outputs, 1.3 µs typical response time, 2 V to 36 V single-supply (or ±1 V to ±18 V dual) operation, common-mode input range that includes ground, 0 to +70 °C (P = PDIP commercial grade). The open-collector outputs with a ground-including input range are the selection point: it runs from a single 5 V rail while sensing signals down to ground, and the outputs wire-OR together for window detectors, level shifters and zero-crossing detectors in limit monitoring, battery supervisors and fan controllers. Selection advice: the P suffix is the PDIP-8 tube version — the same die ships as LM393D/DR (SOIC) for SMD lines; and because it is a comparator rather than an op amp, do not substitute an LM358 here — dedicated comparators switch far faster under saturated conditions and tolerate the high differential input voltages that would latch an op amp. TI lists LM393P as Active. Evidence: TI LM393/LM2903 datasheet and distributor listings confirm dual channels, open-collector, 1.3 µs, 2–36 V, PDIP-8 and tube packing. Match the full LM393P code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.
LM393P is a Dual differential comparator from Texas Instruments, orderable in the PDIP-8 package. The ordering code fixes the exact configuration you receive — package, grade and packing — so procurement starts with matching this code character-for-character against your BOM, not just the base series name.
When you request a quote, include the full ordering code, the target packing format (reel, tube, tray or cut tape), your quantity and any date-code or lot requirements. We reconfirm manufacturer, suffix, package, date code and traceability against the actual offered lot before any commercial quote is issued, and every RFQ gets a reply within 24 hours.

Browse existing catalog records — same series first, then the same category and manufacturer. These are not confirmed replacements; compatibility requires engineering review.
Every suffix in a manufacturer ordering code identifies one exact orderable device — package, temperature grade, packing format or a revision. LM393P names the PDIP-8 configuration; a code that differs by even one suffix character may be a different device. Always quote the complete code exactly as it appears on your BOM.
The package (PDIP-8) is the physical form of the device itself. Packing describes how the devices are delivered — reel, tube, tray or cut tape. The same ordering code can ship in different packing formats depending on the lot, so confirm the required packing format when you submit your RFQ.
Traceability evidence — lot and date-code information, labels and photos — is confirmed per lot at quotation time, because it depends on the actual lot offered. Tell us which documents your receiving inspection requires when you submit the RFQ, and we will confirm what can be provided for the offered lot.
Add LM393P to your RFQ with the complete ordering code, the manufacturer (Texas Instruments), your quantity, the target packing format and any date-code requirements. We reply to every RFQ within 24 hours.
