LM239DT Description

Short technical summary and product information.

The STMicroelectronics LM239DT is a versatile general-purpose comparator IC. It is designed to provide high-speed comparison of analog signals, making it suitable for various electronic circuits. The device features a wide operating voltage range, supporting single or dual supplies from 2V to 32V.

 

Key electrical characteristics include a low quiescent current of 2mA maximum and a typical output current of 16mA at 5V. The input offset voltage is a maximum of 5mV at 30V, with a maximum input bias current of 0.25µA at 5V. The comparator supports multiple output types, including CMOS, DTL, ECL, MOS, Open-Collector, and TTL.

 

This component is housed in a 14-SOIC surface-mount package, facilitating integration into compact PCB designs. It operates reliably within a temperature range of -40°C to 105°C. The LM239DT is part of a family of comparators and is often used in applications requiring precise voltage level detection and switching.
