LM339PWRE4

Overview

The LM339PWRE4 is a quad differential comparator manufactured by Texas Instruments, housed in a 14-pin TSSOP surface-mount package. It operates on a single supply voltage ranging from 2 V to 30 V or dual supplies of ±1 V to ±15 V. The device features an open-collector output configuration with a typical propagation delay of 1.3 µs. Input characteristics include a maximum input offset voltage of 5 mV and an input bias current of 250 nA. Each channel provides an output current capability of 6 mA. The component functions within a commercial temperature range of 0°C to +70°C and includes no shutdown mode.

Feature Summary

• Integrates four independent differential comparators within a single compact integrated circuit.
• Features open-collector outputs that facilitate wired-AND connections and compatibility with various logic families.
• Designed for operation from a single power supply, simplifying system design and reducing component count.
• Provides high common-mode input voltage range that includes ground potential.

Applications

• Overvoltage and undervoltage detection circuits
• Threshold detection and level sensing applications
• Simple pulse generation and timing circuits

Procurement Notes

Verify the specific suffix RE4 indicates RoHS compliance and green material status as per Texas Instruments documentation. Confirm the TSSOP-14 package dimensions match the target PCB footprint. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability.

Selection Notes

Select this component when a low-cost, quad comparator solution is required for single-supply systems. The open-collector output allows for flexible interfacing with different voltage levels. Consider the 1.3 µs propagation delay for speed-sensitive applications. Verify that the 6 mA sink current is sufficient for the load requirements without external buffering.

Part Context

The LM339 series represents a family of low-power quad comparators widely used in industrial and consumer electronics. The LM339PWRE4 is the tape-and-reel version of the LM339PWR, optimized for automated surface-mount assembly processes. It belongs to the standard LMx39/LM2901 family, offering pin-compatible alternatives across different temperature grades and performance specifications.
