Overview
The LM339PWRG4 is a quad differential comparator manufactured by Texas Instruments, housed in a 14-pin TSSOP surface-mount package. It operates within a supply voltage range of 2V to 30V single or ±1V to ±15V dual. Key electrical parameters include a maximum input offset voltage of 5mV at 30V and a maximum input bias current of 0.25µA at 5V. The device features open-collector outputs with a typical output current of 20mA. It functions across an operating temperature range of 0°C to 70°C and complies with RoHS standards.
Feature Summary
- Integrates four independent differential comparators within a compact 14-pin TSSOP package for space-constrained designs.
- Features open-collector outputs capable of sinking up to 20mA, facilitating direct interfacing with various logic families.
- Operates on a wide single or dual power supply range, supporting voltages from 2V to 30V.
Applications
- General-purpose analog signal comparison circuits
- Voltage monitoring systems
- Simple pulse generation applications
Procurement Notes
Verify the specific suffix 'G4' confirms lead-free composition and RoHS compliance as per manufacturer specifications. Ensure the TSSOP-14 package footprint matches the target PCB design. Confirm the commercial temperature grade (0°C to 70°C) aligns with the operational environment requirements before finalizing procurement.
Selection Notes
Select this component when multiple independent comparisons are required in a small form factor. The open-collector output allows flexible pull-up voltage selection. Consider the 5mV input offset voltage limit for precision requirements. Verify that the 20mA output drive capability meets the load requirements without external buffering.
Part Context
This part belongs to the LM339 family of quad comparators, a widely used standard in analog circuit design. The 'PWR' designation indicates the TSSOP-14 package variant, while 'G4' signifies environmental compliance. It serves as a general-purpose alternative to op-amps configured as comparators, offering faster response times and optimized output stages for digital interfacing.
Replacement Considerations
LM339DR: Same quad comparator function in SOIC-14 package; verify pinout compatibility. LM339N: Through-hole DIP-14 equivalent; requires different mounting strategy. LM2903: Automotive-grade variant with similar electrical characteristics but potentially different qualification standards.
