Overview
The LM393BIDGKR is a dual differential comparator manufactured by Texas Instruments, belonging to the LM393B series. It features an open-collector output compatible with CMOS and TTL logic families. The device operates within a supply voltage range of 2 V to 36 V single supply or ±1 V to ±18 V dual supply. 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 supports a wide operating temperature range from -40 °C to +85 °C and is housed in an 8-pin VSSOP package.
Feature Summary
- Dual differential comparison architecture for signal processing
- Open-collector output interface ensuring compatibility with various logic standards
- Wide single and dual power supply operational capability
- Rail-to-rail input functionality for extended dynamic range
Applications
- Over-voltage and under-voltage detection circuits
- Window comparator configurations
- Temperature sensing threshold monitoring
- Level shifting and logic interface conversion
Procurement Notes
Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status and specific tape-and-reel packaging requirements prior to procurement. Ensure the supplier provides valid traceability documentation matching the manufacturer's part identification codes.
Selection Notes
Select this component when dual independent comparison is required within a compact surface-mount footprint. Consider the 5 mV input offset voltage specification for precision applications. Evaluate the 1.3 µs propagation delay against system timing constraints. Verify that the open-collector output configuration aligns with the downstream load requirements.
Part Context
This device is part of the broader LM393 family of low-power dual comparators produced by Texas Instruments. It shares functional similarities with the LM193, LM293, and LM2903 series, differentiated primarily by manufacturing grade and specific parameter tolerances. The 'B' suffix indicates a specific performance bin within the standard LM393 product line.
Replacement Considerations
LM393IDGKR: Direct pin-compatible alternative with standard commercial grade specifications.
