It compares two analog input voltages and drives the output low when the non-inverting input is below the inverting input. The open-collector output stage sinks current to ground, making it compatible with CMOS, DTL, ECL, MOS, and TTL logic families — a deliberate interface choice that lets the comparator pull down a pull-up resistor tied to whatever logic rail the downstream circuit uses.
Supply range and temperature — where this part fits
The single-supply range runs from 2 V to 36 V, or ±1 V to ±18 V with dual supplies.
Texas Instruments no longer manufactures this specific through-hole variant.
Key parametric limits for design-in
Quiescent supply current maxes at 2.5 mA for both comparators — low enough for battery-powered threshold detection. Input offset voltage is 5 mV max at 30 V supply, which sets the detectable voltage difference floor. Input bias current is 0.25 µA max at 5 V, so source impedance matters: a 100 kΩ source adds 25 mV of offset error. Output sink current is 18 mA typical at 5 V, enough to drive a logic input or an LED directly.
