Frequently Asked Questions
What is the supply voltage range of LM2903D?
The LM2903D operates from a single supply of 2V to 36V, or a dual supply of +/-1V to +/-18V. This wide range makes it compatible with 3.3V, 5V, 12V, and 24V systems commonly found in industrial and consumer applications.
What package is the LM2903D available in?
The LM2903D comes in an SOIC-8 (D suffix) package with 8 pins on a 1.27mm pitch. Texas Instruments also offers the same die in PDIP-8 (N suffix) and SOT-23-8 (DCK suffix) packages for different board space requirements.
What are good substitutes for LM2903D?
Pin-compatible alternatives include the LM393D (industry standard equivalent from multiple vendors), TS393IDT from STMicroelectronics, and MC33902D from onsemi. All are dual comparators in SOIC-8 with similar electrical specs.
What is the operating temperature range of LM2903D?
The LM2903D is rated for -40C to +125C, qualifying it for industrial-grade applications. This broad range suits automotive auxiliary circuits, outdoor equipment, and factory automation where extreme ambient temperatures are common.
How does the open-collector output work on LM2903D?
The LM2903D has open-collector outputs, meaning each output transistor pulls the output pin low when active but leaves it floating when inactive. An external pull-up resistor (typically 10kOhm) connected to the desired logic voltage is required, enabling wire-OR configurations and direct interfacing to both TTL and CMOS logic families.
