TLC551CP TI Comparator | 8-PDIP | Single, Open-Collector Output

Product Overview

The TLC551CP is a single, low-power, precision comparator from Texas Instruments, designed for applications requiring high accuracy and low supply current. It features an open-collector output stage, making it suitable for interfacing with various logic families. The device operates from a single supply voltage range of 2V to 15V or dual supplies of ±1V to ±7.5V. Its low offset voltage and high gain ensure reliable performance in precision sensing and threshold detection circuits. Housed in an 8-pin PDIP package, the TLC551CP is ideal for through-hole PCB designs.
