LM239APT
Overview
The LM239APT is a high-precision quad independent voltage comparator designed to operate over a wide range of supply voltages from 2V to 32V. This device features an open-collector output stage, making it compatible with TTL, DTL, ECL, MOS, and CMOS logic levels through the use of external pull-up resistors. With four elements in a single 14-TSSOP package, it provides a compact solution for multi-channel signal monitoring and level detection.
Why Choose This Part
The LM239APT offers significant flexibility with its wide supply voltage range and very low input bias current of 0.1uA at 5V. Its quad-channel configuration in a space-saving TSSOP14 package allows for high-density PCB layouts, while the open-collector architecture enables easy wired-OR connections and multi-voltage logic interfacing.
Applications
Key Specifications
Getting Started
To use the LM239APT, connect the VCC and ground pins to a stable power source between 2V and 32V and remember to include external pull-up resistors on the outputs to define the high-state logic level. Engineers can prototype designs using a standard 14-pin TSSOP breakout board on a breadboard or verify switching performance with a SPICE simulator using the manufacturer's macro-models.
