Overview
The LM393DRG4 is a dual differential analog comparator manufactured by Texas Instruments, housed in an SOIC-8 surface-mount package. It operates within a supply voltage range of 2 V to 30 V and draws a typical operating current of 2.5 mA. The device features a response time of 1.3 µs, an input offset voltage of 5 mV, and an input bias current of 50 nA. Designed for commercial temperatures between 0°C and +70°C, it supports CMOS and TTL output logic levels without a shutdown function.
Feature Summary
- Dual-channel differential comparison architecture
- CMOS and TTL compatible open-collector outputs
- Wide single-supply voltage operation capability
Applications
- Over-voltage detection circuits
- Window comparator configurations
- Level shifting interfaces
Procurement Notes
Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status via official documentation. Check for End-of-Life notices as the product lifecycle may be limited. Validate package markings against datasheet specifications to ensure correct part identification before integration into production systems.
Selection Notes
Select this component for applications requiring dual independent comparators in a compact surface-mount form factor. Ensure the required supply voltage remains within the 2 V to 30 V operational limits. Consider the 1.3 µs response time when designing high-speed signal processing paths. Verify that the open-collector output configuration aligns with the downstream logic requirements.
Part Context
This device belongs to the LM393 series of dual comparators from Texas Instruments. It shares functional similarities with other members like the LM393DRG3 but carries specific manufacturing suffixes indicating packaging or revision details.
