The trade-off is a 300 µs max propagation delay, so this part targets low-frequency threshold sensing: battery-voltage monitors, over-temperature flags, power-good indicators, and wake-up circuits where the comparator sits on the rail continuously. The CMOS and open-drain output options let it interface directly to a microcontroller GPIO or a logic-level interrupt line without a pull-up resistor on the CMOS side. ## 950 nA quiescent — the battery-life number At 950 nA max for both channels, the TLV3402CD draws less than 1 µA from the supply rail. In a battery-powered sensor node running from a 240 mAh coin cell, this comparator alone consumes about 0.4% of the battery capacity per year just sitting there. That is the decision driver: if your system needs a comparator that never sleeps and the signal is slow (temperature, voltage level, pressure), this part lets you skip the duty-cycle overhead. The 250 pA max input bias current at 15 V means the external resistor divider for the threshold reference can use high-value resistors without loading the input — a 10 MΩ divider string adds only 2.5 µV of offset error from the bias current. ## 300 µs propagation delay — the speed envelope The 300 µs max propagation delay is the anchor for the application space. This comparator handles DC threshold crossing: a battery dropping below a threshold, a thermistor voltage crossing a trip point, a capacitor charging past a reference. ## Supply range and output flexibility The 2.5 V to 16 V single-supply range (or ±1.25 V to ±8 V dual-supply) covers common rails without a secondary regulator. The CMOS output swings rail-to-rail; the open-drain output lets you wire-OR multiple comparators to a shared interrupt line with a single pull-up resistor. ## CMRR and PSRR — noise rejection on a tight power budget Typical CMRR of 88 dB and PSRR of 105 dB are strong numbers for a nanopower comparator. They mean the threshold accuracy holds up when the common-mode voltage shifts or the supply rail has ripple. ## Package and mounting The supplier device package is 8-SOIC.","metaTitle":"TLV3402CD dual nanopower comparator, 950 nA quiescent","metaDescription":"TI TLV3402CD dual general-purpose comparator with 950 nA max quiescent current, 300 µs propagation delay, CMOS/open-drain output, 8-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Type":"General Purpose","Package":"Tube","Output Type":"CMOS, Open-Drain","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","CMRR, PSRR (Typ)":"88dB CMRR, 105dB PSRR","Number of Elements":"2","Operating Temperature":"0°C ~ 70°C","Current - Output (Typ)":"10mA","Propagation Delay (Max)":"300µs","Supplier Device Package":"8-SOIC","Current - Quiescent (Max)":"950nA","Current - Input Bias (Max)":"250pA @ 15V","Voltage - Input Offset (Max)":"3.6mV @ 15V","Voltage - Supply, Single/Dual (±)":"2.5V ~ 16V, ±1.25V ~ 8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.09","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.09000","currency":"USD"},{"qty":10,"price":"$2.77300","currency":"USD"},{"qty":25,"price":"$2.62120","currency":"USD"},{"qty":100,"price":"$2.27160","currency":"USD"},{"qty":250,"price":"$2.15512","currency":"USD"},{"qty":500,"price":"$1.93380","currency":"USD"},{"qty":1000,"price":"$1.64850","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/efe6a972d4fd6be881683e7b4942b2cb.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the equivalent or replacement for TLV3402CD?","answer":"There is no official pin-compatible second source listed in the cross-reference data.
