Overview
The LM339LVRTER is a quad-channel analog comparator from Texas Instruments, housed in a 16-pin WQFN (RTE) package. It operates within a supply voltage range of 1.65 V to 5.5 V. Key electrical specifications include a typical input offset voltage of 400 µV and a typical propagation delay of 600 ns. The device features rail-to-rail inputs with failsafe capability and open-collector outputs capable of sourcing up to 6 mA per channel. It functions reliably across an extended temperature range of -40°C to +125°C.
Feature Summary
- Rail-to-Rail input stage with integrated failsafe protection
- Low input offset voltage for high precision applications
- Open-collector output structure supporting flexible logic interfacing
Applications
- Battery-powered systems requiring low voltage operation
- Temperature sensing circuits
- Voltage monitoring applications
Procurement Notes
Verify the specific suffix 'TER' corresponds to the tape-and-reel packaging format on the official datasheet. Confirm the 16-pin WQFN footprint matches the design layout. Ensure the operating temperature range meets environmental requirements. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when low voltage operation below 3.3 V is required compared to standard LM339 variants. The rail-to-rail input feature simplifies interface design with sensors operating near ground or supply rails. The exposed pad thermal enhancement supports heat dissipation in compact layouts. Verify that open-collector outputs align with downstream logic level requirements.
Part Context
This part belongs to the LM339LV family, designed specifically for low-voltage applications. Unlike the standard LM339 which supports higher voltages up to 36 V, the LV variant optimizes performance for single-supply systems ranging from 1.65 V to 5.5 V. It maintains the quad-channel architecture while reducing power consumption and improving offset characteristics.
Replacement Considerations
LM339AN/NOPB offers similar quad-channel functionality but operates at higher voltages (up to 36 V) and uses a PDIP-14 package. LM339LVDR provides comparable low-voltage specs but utilizes an SOIC-14 package. Verify pinout compatibility and thermal management requirements before substituting.
