概要

Description

LMV339MX is a TI quad voltage comparator in the LMV family. It contains four independent comparators with open-collector outputs in a compact MX-pack (MSOP-8/VSSOP-8).
Key points:
- Single-supply operation: 2.7 to 5.5 V
- Input common-mode range includes ground (not rail-to-rail; typically up to Vcc–1.5 V)
- Outputs are open-collector; require external pull-up resistors
- Four channels in one 8-pin package; ideal for threshold, level sensing, and window-detection circuits
- Low-power, suitable for battery-powered and compact designs
Common uses: battery monitoring, zero/over/under-threshold sensing, sensor interfaces, simple A/D front-ends, and safety/limit switches.
For exact electrical specs (offset, bias current, propagation delay, pull-up recommendations, and operating conditions), consult the LMV339 MX datasheet.

Features

Here are key features of LMV339MX:
- Quad low-voltage differential comparator (4 channels)
- Open-collector outputs (each channel); requires external pull-up resistors
- Supply voltage: 1.8 V to 5.5 V
- Input common-mode range includes ground; extends up to approximately Vcc − 1.5 V
- Very low quiescent current (typical per comparator in the tens of µA range)
- Fast propagation delay (typical sub-microsecond to a few microseconds, varies by Vcc/load)
- Extended operating temperature: roughly −40°C to +125°C
- Package: 8-pin MSOP (LMV339MX), RoHS-compliant
Applications: level detection, window detectors, zero-crossing, battery-powered sensing.

Package

LMV339MX comes in a 14‑pin MSOP (Micro Small Outline Package) package.

Pinout

Pin count: 14 pins.
Function: LMV339MX is a quad voltage comparator IC (four independent comparators) with open-collector outputs (requires pull-up resistors).
