Overview
The LM339APWR is a quad differential comparator manufactured by Texas Instruments, housed in a 14-TSSOP surface-mount package. It operates within a supply voltage range of 2 V to 30 V and draws a typical operating supply current of 500 uA. The device features open collector outputs capable of sinking up to 6 mA per channel. Key electrical specifications include a response time of 1.3 us, an input offset voltage (Vos) of 3 mV, and an input bias current (Ib) of 250 nA. It functions reliably across a temperature range of 0°C to +70°C.
Feature Summary
- Integrates four independent differential comparators into a single low-power package
- Features open collector outputs compatible with various logic families
- Operates on a wide single-supply voltage range from 2 V to 30 V
Applications
- Temperature sensing circuits
- Supply voltage monitoring systems
- Logic level conversion interfaces
Procurement Notes
Verify the specific suffix 'PWR' confirms the tape-and-reel packaging format required for automated assembly processes. Confirm RoHS compliance status matches project environmental regulations. Ensure the manufacturer designation aligns with Texas Instruments specifications to avoid counterfeit components during sourcing.
Selection Notes
Select this component when multiple independent comparison functions are needed in a compact surface-mount footprint. Consider the 1.3 us response time and 3 mV offset voltage for applications requiring moderate precision. Verify that the open collector output architecture suits the downstream circuit requirements without additional pull-up resistors.
Part Context
This part belongs to the LM339 family of analog comparators, designed for general-purpose signal processing tasks. It serves as a standard solution for converting analog signals into digital logic levels. The TSSOP-14 package provides a balance between pin count and board space efficiency for consumer and industrial electronics.
Replacement Considerations
LM339PWRE4 is a documented equivalent variant within the same product family.
