Overview
The LM339APWG4 is a quad differential comparator manufactured by Texas Instruments, featuring an open-collector output configuration. 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 provides a per-channel output current capability of 6 mA with a response time of 1.3 us. Input characteristics include a maximum input offset voltage of 3 mV and an input bias current of 250 nA. Designed for surface-mount applications, it is housed in a TSSOP-14 package and supports an operating temperature range from 0 C to +70 C.
Feature Summary
- Integrates four independent differential comparators within a single low-power package.
- Features open-collector outputs compatible with various logic families including CMOS and TTL.
- Operates effectively across a wide single-supply voltage range down to 2 V.
Applications
- Temperature monitoring systems
- Voltage level detection circuits
- Physical sensor signal conditioning
Procurement Notes
Verify the specific suffix 'G4' against the manufacturer's official documentation to confirm compliance details and material composition. Ensure the selected package variant matches the required PCB footprint and thermal management specifications for the target application environment.
Selection Notes
Select this component when a low-power quad comparator solution is required for space-constrained designs. The TSSOP-14 package offers a compact form factor suitable for surface-mount assembly processes. Consider the 1.3 us response time and 3 mV offset voltage limits to ensure adequate performance margins for the intended signal processing tasks.
Part Context
This part belongs to the LM339 family of analog comparators, which are widely utilized for general-purpose voltage comparison tasks. The LM339 series is known for its compatibility with standard logic families and its ability to operate from a single power supply, making it a versatile choice for embedded control and sensing applications.
Replacement Considerations
Direct replacements include the LM339APW and LM339DR. Verify pinout compatibility and electrical parameter alignment before substitution.
