Dual nanopower comparator for always-on threshold sensing
The open-drain output stage allows wire-OR or level-shifting; the CMOS output option provides rail-to-rail swing. Supply range spans 2.7 V to 16 V (or ±1.35 V to ±8 V split). Propagation delay is 300 µs maximum — slow by modern comparator standards, but entirely acceptable for DC threshold alarms, over-temperature detection, under-voltage lockout, or any loop where the event time constant is in the millisecond range. The 88 dB CMRR and 105 dB PSRR keep the trip point stable even when the supply or common-mode voltage shifts, which matters in noisy industrial or automotive environments.
The 950 nA per channel quiescent current is the defining spec. In a battery-powered sensor node, a comparator drawing microamps instead of nanoamps can cut standby life by months. The TLV3402ID keeps the threshold monitor alive continuously without a load switch or duty-cycling.
Stock it as a line item with confidence that the factory will still be shipping it when the next production run starts.
Sourcing and fit for production
The 8-SOIC package is widely used, so no exotic handling or dry-storage requirements beyond standard MSL precautions. If you are consolidating comparator SKUs, the dual-channel TLV3402ID replaces two single-channel nanopower comparators in the same footprint, saving board space and reducing inventory lines.
