LM339DTBR2G

Overview

The LM339DTBR2G is a single-supply quad comparator manufactured by onsemi, housed in a TSSOP-14 package. It operates within a supply voltage range of 3.0 V to 36 V or split supplies of ±1.5 V to ±18 V. The device features low input bias current (25 nA typical) and low output saturation voltage (130 mV typical at 4.0 mA). It supports TTL and CMOS logic compatibility and includes ESD protection on inputs.

Feature Summary

• Single and split supply operation capability
• Low input bias and offset characteristics
• TTL and CMOS compatible outputs
• Integrated input ESD protection

Applications

• Level detection circuits
• Low-level sensing applications
• Memory applications

Procurement Notes

Verify the specific suffix DTBR2G corresponds to the TSSOP-14 package variant when sourcing. Confirm RoHS compliance and Pb-Free status as indicated in the ordering information. Ensure the operating temperature range aligns with system requirements for commercial grade devices.

Selection Notes

Select this component for designs requiring multiple independent comparators in a compact surface-mount footprint. Consider the open-collector output structure which necessitates external pull-up resistors. Evaluate the propagation delay specifications against signal speed requirements for the target application.

Part Context

This part belongs to the LM339 family of quad comparators from onsemi. It shares functional similarities with other industry-standard quad comparators but offers specific performance metrics regarding input bias current and saturation voltage suitable for general-purpose analog switching tasks.

Replacement Considerations

Compatible substitutes include LM239, LM2901, and MC3302 variants from onsemi, provided pinout and electrical characteristics match the design constraints.
