Product Overview
The TLC372CP from Texas Instruments is a dual differential comparator featuring low power consumption and high speed. It operates from a single supply voltage range of 3V to 16V or dual supplies of ±1.5V to ±8V. The device offers a typical response time of 1.1μs at 5V, making it suitable for battery-powered and portable applications. The open-collector outputs allow wired-OR connections. Housed in an 8-pin PDIP package, it is ideal for through-hole PCB designs.
