The wide supply range from 2 V to 36 V single supply, or ±1 V to ±18 V dual supplies, makes it suitable for interfacing between different voltage domains in industrial control, power supply monitoring, and threshold detection circuits. With a maximum input offset voltage of 2 mV at 30 V and a maximum input bias current of 0.25 µA at 5 V, the LM393APG4 provides adequate precision for general-purpose comparator applications without the cost of precision-grade parts. ## Supply flexibility and quiescent budget The 2 V to 36 V single-supply range covers 3.3 V, 5 V, 12 V, and 24 V industrial rails without needing a separate regulator. The maximum quiescent current of 2.5 mA per device is the total for both comparators — budget this into the system power calculation for always-on monitoring functions. The open-collector output type (CMOS, MOS, TTL compatible) allows wired-OR connections and level shifting to higher or lower voltage logic families. The 20 mA typical output sink current drives relays, LEDs, or logic inputs directly. ## Commercial temperature grade — indoor and controlled environments ## Through-hole PDIP-8 — legacy assembly compatibility The 8-DIP (0.300\", 7.62mm) through-hole package with 8-PDIP supplier device package designation is suited for prototyping, low-volume production, or designs where wave soldering is preferred over reflow. The 0.100-inch pin pitch is breadboard- and perfboard-friendly. This removes the supply-chain risk of forced redesign for ongoing production runs.","metaTitle":"LM393APG4 Dual General Purpose Comparator, PDIP-8, 2V-36V","metaDescription":"Texas Instruments LM393APG4 dual general-purpose comparator in 8-PDIP. 2V to 36V supply, 2.5mA quiescent max, 0°C to 70°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Type":"General Purpose","Series":"-","Package":"Tube","Hysteresis":"-","Output Type":"CMOS, MOS, Open-Collector, TTL","Mounting Type":"Through Hole","Package / Case":"8-DIP (0.300\\\", 7.62mm)","lifecycle_stage":"eol_hot","CMRR, PSRR (Typ)":"-","Number of Elements":"2","Base Product Number":"LM393","Operating Temperature":"0°C~70°C","Current - Output (Typ)":"20mA","Propagation Delay (Max)":"-","Supplier Device Package":"8-PDIP","Current - Quiescent (Max)":"2.5mA","Current - Input Bias (Max)":"0.25µA @ 5V","Voltage - Input Offset (Max)":"2mV @ 30V","Voltage - Supply, Single/Dual (±)":"2V ~ 36V, ±1V ~ 18V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/bfc800f2c0b26660b0616334552ba434.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM393APG4/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to LM393APG4?","answer":"The LM393P is the same-function dual comparator in the same PDIP-8 package with identical pinout and similar specifications.
