TILM2901BIPWR

Overview

The LM2901BIPWR is a quad-channel differential comparator featuring an open-collector output and a wide supply voltage range up to 36V. This 'B' version represents an updated design from Texas Instruments with improved performance specifications, such as a lower quiescent current of 1.2mA max, and is housed in a space-saving 14-TSSOP package. It is designed to operate reliably across a broad temperature range of -40C to 125C, making it suitable for industrial environments.

Why Choose This Part

This device offers high flexibility with its wide input common-mode range that includes ground, even when operating from a single supply. The open-collector output configuration allows for wired-OR connections with multiple outputs, simplifying complex logic architectures. Furthermore, the 1us typical propagation delay and 21mA typical output sink current provide robust switching performance for a variety of loads.

Applications

Getting Started

To evaluate this part, use a standard TSSOP-14 breakout board for breadboard prototyping. Ensure a pull-up resistor is connected between the output pin and the desired logic supply voltage (up to 36V) since the open-collector output cannot drive high on its own. For high-speed applications, keep trace lengths short to minimize the effect of parasitic capacitance on the rise time determined by the pull-up resistor.
