Unisonic LM339 Quad Differential Comparator Datasheet
The LM339 linear integrated circuit contains four independent voltage comparators designed for single‑supply operation over a wide voltage range. It features low power consumption, low input bias current, and open‑collector outputs that are compatible with TTL, DTL and CMOS logic families.
Key specifications include a supply voltage range of 2 V to 36 V, typical supply current of 0.8 mA, input bias current of 25 nA, and output saturation voltage low enough for reliable logic interfacing. The device is offered in DIP‑14, SOP‑14, and TSSOP‑14 packages. This manual is written in Chinese.
