Product details

Quad comparator in a 14-TSSOP — what the package and temp grade tell you

The LM2901PWG4: The open-collector output stage (compatible with CMOS, MOS, and TTL logic) lets you wire-AND multiple outputs or drive loads up to 20 mA typical per channel. The 2.5 mA max quiescent current for all four comparators keeps the power budget tight in multi-channel sensing and threshold-detection circuits.

Supply range and input offset — where the ratings matter for your BOM

The 2 V to 30 V single-supply range covers industrial rails without a secondary regulator. The 7 mV max input offset at 30 V sets the voltage-sensing resolution floor. Input bias current is 0.25 µA max at 5 V, which keeps the voltage drop across high-impedance source resistors low. The 14-TSSOP footprint (4.40 mm width) fits on dense mixed-signal boards.

For BOM lines that need a qualified quad comparator in a 14-TSSOP, this is a direct fit with no end-of-life risk in the near term.
