This document is a product specification for the LM139/239/239A/339/339A /LM2901/MC3302 Quad voltage comparator
The LM139 series consists of four independent precision voltage comparators designed for single‑supply operation over a wide voltage range and with low power consumption. They feature input common‑mode voltage that includes ground and are compatible with TTL, CMOS, MOS and ECL logic families.
The data sheet provides absolute maximum ratings, DC and AC electrical characteristics, typical performance graphs, pin configurations and ordering information for the LM139, LM239, LM339, LM2901 and MC3302 devices.
| Supply voltage range | 2.0 Vpc to 36 Vpc (single) or +1.0 Vp to +18 Vpc (dual) |
|---|---|
| Supply current per comparator | 0.8 mA (independent of supply voltage) |
| Input offset voltage | as low as 2.0 mV max |
| Input bias current | 25 nA typical |
| Output saturation voltage | 250 mV at 4 mA |
| Maximum power dissipation (F package) | 1190 mW |
| Operating temperature range (LM139) | -55 °C to +125 °C |
It operates from 2.0 Vpc up to 36 Vpc on a single supply, or from +1.0 Vp to +18 Vp on dual supplies.
Each comparator draws about 0.8 mA, independent of the supply voltage.
The input offset voltage is specified as low as 2.0 mV maximum per comparator.
The maximum output current is approximately 20 mA, independent of the magnitude of V+.
