The TLV9022DDFR is a dual-channel general-purpose comparator from Texas Instruments, packing two independent comparators into a TSOT-23-8 package. The open-drain, rail-to-rail output stage lets it interface with logic families running at different supply voltages without a separate level translator. Propagation delay maxes at 100 ns, which sets the ceiling for the comparator's response in a closed-loop or threshold-detection path — a 10 MHz signal at the input will be edge-ambiguous.
Temperature grade and quiescent current — bench and field limits
The 30 µA max quiescent current per channel keeps the thermal budget tight in a densely populated board; two comparators running draw under 60 µA total, which matters for loop-powered or battery-backed designs. Input offset voltage is trimmed to 1.5 mV max at 5 V — this is the DC error the comparator adds to the threshold. For a 10 mV hysteresis band, a 1.5 mV offset consumes 15 % of the margin; a precision reference or a larger hysteresis resistor may be needed if the trip point must hold within 1 %.
The TSOT-23-8 footprint is a 2.9 mm × 1.6 mm body with 0.65 mm pitch — the same land pattern as a standard SOT-23-8, so existing PCB layouts for that footprint accept this comparator without a board spin. The supplier device package is listed as TSOT-23-8, which is the same mechanical outline as the SOT-23-8 but with a thinner body (0.9 mm vs 1.1 mm); the soldering profile is identical.
No pin-compatible successor or cross-reference is recorded — the TLV9022DDFR is the current-generation part in this TSOT-23-8 dual-comparator family. For a BOM line that calls out this order code, the fit is direct: same package, same supply range, same temperature grade.
