Overview
The LM339LVPWR is a low-voltage, standard quad-channel comparator manufactured by Texas Instruments. It operates on a single or dual supply voltage ranging from 1.65V to 5.5V. The device features open-collector outputs that support rail-to-rail operation. Key electrical specifications include a maximum propagation delay of 600ns and a typical CMRR of 65dB with PSRR at 80dB. The quiescent current is limited to a maximum of 35µA. It is housed in a 14-TSSOP package and functions within an operating temperature range of -40°C to 125°C.
Feature Summary
- Quad-channel configuration for multiple comparison tasks
- Low voltage operation supporting 1.65V to 5.5V supplies
- Rail-to-rail output capability with open-collector structure
- Low quiescent current consumption
Applications
- Battery-powered systems requiring low power consumption
- Threshold detection circuits
- Voltage monitoring applications
- General purpose analog signal processing
Procurement Notes
Verify the specific suffix 'PWR' corresponds to the TSSOP-14 package variant when sourcing. Confirm the manufacturer is Texas Instruments to ensure compatibility with specified electrical parameters such as the 600ns propagation delay and 35µA max quiescent current. Check for RoHS compliance status if required by assembly standards. Ensure the operating temperature range meets the environmental requirements of the target application.
Selection Notes
Select this component when a quad comparator is needed with low voltage operation down to 1.65V. It is suitable for designs prioritizing low power consumption due to its 35µA max quiescent current. The rail-to-rail output feature allows for direct interfacing with logic families without additional level shifting. Consider the 14-TSSOP package size for space-constrained PCB layouts.
Part Context
This part belongs to the LM339LV family of low-voltage comparators. It serves as a quad-channel version within Texas Instruments' portfolio of general-purpose analog comparators. The device is designed to replace higher voltage counterparts in modern low-power electronics. It shares functional similarities with other LV series parts but offers four independent channels in a single package.
Replacement Considerations
The LM339PWR is a related quad differential comparator from the same manufacturer. Verify pinout and electrical parameter compatibility before substitution.
