Overview
The LM139DR is a quad general-purpose analog comparator manufactured by Texas Instruments. It features four independent differential comparators in a single SOIC-14 package. The device operates with a wide supply voltage range from 2 V to 36 V and consumes a typical quiescent current of 500 uA. Key electrical parameters include a response time of 300 ns, an input offset voltage of 5 mV, and an input bias current of 25 nA. Each output channel can source up to 6 mA. The component supports rail-to-rail output capabilities and functions within an operating temperature range of -55°C to +125°C.
Feature Summary
- Integrates four independent differential comparators for multi-channel signal processing
- Supports wide single-supply voltage operation from 2 V to 36 V
- Provides rail-to-rail output capability compatible with various logic families
- Operates reliably across extended industrial temperature ranges
Applications
- General-purpose voltage monitoring circuits
- Level detection systems
- Simple time delay generation
- Waveform shaping applications
Procurement Notes
Verify the specific suffix 'DR' indicates the tape-and-reel packaging format when ordering. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to procurement. Ensure the selected variant matches the required SOIC-14 surface-mount package dimensions for PCB layout compatibility.
Selection Notes
Select this component when multiple independent comparison functions are required in a compact footprint. The low power consumption makes it suitable for battery-operated devices. Verify that the 300 ns response time meets the speed requirements of the target application. Consider the 5 mV input offset voltage tolerance for precision threshold settings.
Part Context
The LM139 series belongs to Texas Instruments' family of quad analog comparators. The LM139DR is the surface-mount reel version of the LM139D. It shares functional similarities with the LM239 and LM339 but offers extended temperature specifications compared to commercial grade variants. The device serves as a standard solution for basic analog-to-digital interface tasks.
