Overview
The LP339DR is a quad differential comparator manufactured by Texas Instruments, housed in a 14-SOIC surface-mount package. It operates on a single or dual power supply ranging from 2 V to 30 V. The device features an open-collector output type and supports up to four independent channels. Key electrical specifications include a maximum input offset voltage of 5 mV at 30 V, a typical response time of 1.3 µs, and a quiescent current of 2.5 mA. It functions within a commercial temperature range of 0°C to +70°C.
Feature Summary
- Integrates four independent differential comparators for multi-channel signal processing
- Supports wide single-supply or split dual-supply voltage operation
- Features open-collector outputs compatible with various logic families
Applications
- General-purpose analog signal comparison circuits
- Voltage monitoring systems
- Threshold detection applications
Procurement Notes
Verify the specific suffix 'DR' confirms the tape-and-reel packaging format and SOIC-14 footprint. Confirm RoHS compliance status as indicated in official datasheets. Ensure the operating temperature range meets system requirements. Cross-reference the manufacturer part number against current obsolescence notices to confirm active production status before finalizing procurement plans.
Selection Notes
Select this component when a quad comparator configuration is required in a surface-mount design. The LP339DR offers a balance of speed and power consumption suitable for general-purpose applications. Consider the open-collector output limitation which requires external pull-up resistors. Compare against the through-hole LP339N variant if PCB layout constraints differ.
Part Context
This device belongs to the LM339/LP339 family of low-power quad comparators. While functionally similar to the standard LM339, the LP339 series typically emphasizes lower power consumption characteristics. The DR suffix specifically denotes the reel-packaged version of the SOIC-14 plastic small-outline integrated circuit, distinguishing it from tube-packed variants.
Replacement Considerations
Direct pin-compatible substitutes include the LM339DR and LP339N/NOPB (with package adaptation). Verify that replacement parts match the required supply voltage range and output drive capabilities.
