Key Features
- Dual independent differential comparators in a single 8-pin SOIC package, enabling two separate voltage comparison functions with minimal PCB area
- Open-collector outputs allow wired-OR connections and flexible output voltage level shifting to interface with different logic families
- Low input bias current of 0.4 µA maximum enables accurate comparison of signals from high-impedance sources without loading the reference
- Wide supply voltage range supports single or dual supply operation, making it versatile for battery-powered and industrial 5V/15V systems
Applications
The LM293DE4 dual comparator is used in voltage level detection, threshold monitoring, and logic signal conversion in industrial control systems, power supplies, and embedded electronics. It is commonly applied in window comparator circuits, zero-crossing detectors, and PWM generation where two independent comparison channels are needed in a small package. The open-collector output configuration makes it well-suited for bus-wire applications and interfacing between different logic voltage domains in mixed-signal systems.

Frequently Asked Questions
What is the output type of the LM293DE4?
The LM293DE4 features open-collector outputs, which allow multiple comparator outputs to be wire-ORed together on a shared bus line. The open-collector configuration also enables flexible interfacing to different logic voltage levels by using an appropriate pull-up resistor connected to the desired output voltage supply.
What are the input bias current specifications of the LM293DE4?
The LM293DE4 has a typical input bias current of 0.25 µA at 25°C and a maximum of 0.4 µA, allowing it to accurately compare voltages from moderately high-impedance signal sources without introducing significant loading errors in precision threshold detection applications.
What package does the LM293DE4 use?
The LM293DE4 is housed in an 8-pin SOIC (Small Outline Integrated Circuit) surface-mount package, identified by JESD-30 code R-PDSO-G8, with plastic epoxy body construction. This package provides a compact, low-profile footprint suitable for automated PCB assembly in consumer and industrial electronics.
What applications is the LM293DE4 comparator used for?
The LM293DE4 is used in voltage threshold detection, window comparators, oscillators, PWM controllers, and zero-crossing detectors. Its dual channels and open-collector outputs make it ideal for industrial automation, motor control, power supply feedback circuits, and logic-level translation between different voltage domains in embedded systems.
