Overview
The LM239DRG4 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 supply voltage range of 2 V to 30 V and draws a typical quiescent current of 500 uA per channel. It provides an open-collector output capable of sinking up to 6 mA, compatible with CMOS and TTL logic families. The input offset voltage is typically 5 mV, with an input bias current of 250 nA. The response time is specified at 300 ns. It functions within an operating temperature range of -25°C to +85°C.
Feature Summary
- Integrates four independent high-gain differential comparators for multi-channel signal processing
- Features open-collector outputs allowing flexible interfacing with various digital logic families
- Operates over a wide single-supply voltage range from 2 V to 30 V
- Designed for low power consumption with minimal quiescent current draw
Applications
- General-purpose voltage monitoring and threshold detection circuits
- Interface between analog sensors and digital logic systems
- Simple pulse generation and timing applications
- Over-voltage and under-voltage protection circuits
Procurement Notes
Verify the specific suffix 'G4' indicates lead-free composition and RoHS compliance as per Texas Instruments standards. Confirm the SOIC-14 package dimensions match your PCB footprint requirements. Ensure the operating temperature range of -25°C to +85°C meets your environmental specifications. Cross-reference the datasheet revision date to ensure compatibility with your design parameters.
Selection Notes
Select this component when multiple independent comparisons are required in a compact surface-mount package. It is suitable for designs needing wide supply voltage flexibility and low static power consumption. Consider the open-collector output structure for level shifting or wired-OR configurations. Verify that the 300 ns propagation delay is sufficient for your application speed requirements.
Part Context
The LM239DRG4 belongs to the LM239 family of quad comparators. It is a lead-free, RoHS-compliant version of the standard LM239DR. This part is part of Texas Instruments' broader portfolio of linear integrated circuits, specifically within the analog comparator category. It shares functional similarities with other members like the LM139 and LM339 but offers specific commercial-grade temperature ratings.
FAQ
