TLC339CDB TI Comparator | Quad, Open Collector, 4.5us, 2V-18V

Product Overview

The TLC339CDB is a quad CMOS voltage comparator from Texas Instruments, featuring open-collector outputs. It operates from a single supply voltage range of 2V to 18V or dual supplies of ±1V to ±9V. With a typical response time of 4.5 µs, it is designed for low-power applications requiring high input impedance and rail-to-rail input capability. The device is available in a 14-pin SOIC package (DB suffix) and is specified for the industrial temperature range of -40°C to +85°C.
