概要
Description
LM393EDR2G is Texas Instruments’ LM393 dual voltage comparator in an RoHS-compliant 8-pin EDR package. It contains two independent comparators with open-collector outputs, designed for low-power threshold and level-detection tasks on a single supply.
Key points:
- Two comparators, open-collector outputs (need pull-up resistors to Vcc)
- Supply range: 2–36 V; input common-mode includes ground
- Quick switching (propagation delay in the microsecond range, depending on conditions)
- Temperature range typically -40°C to +125°C
- Package: 8-pin, RoHS-compliant (EDR variant)
Typical usage:
- Connect Vcc to your supply, GND to ground
- Inputs to the signals you want to compare
- Outputs require pull-ups to your logic level
- Pinout (8-pin package): 1 = Output A, 2 = In− A, 3 = In+ A, 4 = GND, 5 = In+ B, 6 = In− B, 7 = Output B, 8 = Vcc
Applications include battery monitoring, level sensing, window detectors, and zero-crossing circuits.

Application
LM393EDR2G is a dual comparator (open-collector outputs). Common applications include:
- Battery/ power-supply monitoring: under/over-voltage protection
- Threshold and window detectors (two comparators for a window)
- Zero-cross detectors for AC switching and triac/relay drive
- Level shifting and signal conditioning for microcontroller inputs
- Relay/LED/motor drive interfaces using open-collector outputs
- Sensor conditioning (thermistors, photodiodes, Hall sensors) with hysteresis
These use cases leverage its wide supply range, fast response, and open-collector outputs.
