Overview
The LM193DRG4 is a dual differential comparator manufactured by Texas Instruments, housed in an SOIC-8 surface-mount package. It operates within a supply voltage range of 2 V to 36 V and supports CMOS and TTL output compatibility. The device features a propagation delay of 1.3 µs, an input offset voltage of 5 mV, and an input bias current of 50 nA. It draws 2.5 mA of operating supply current and functions reliably across a temperature range of -55°C to +125°C.
Feature Summary
- Dual differential comparison architecture for precise signal threshold detection
- Wide single-supply voltage operation supporting up to 36 V
- CMOS and TTL logic interface compatibility for versatile system integration
Applications
- Over-voltage and under-voltage protection circuits
- Threshold detection systems
- Logic level shifting interfaces
Procurement Notes
Verify the specific suffix 'G4' against the manufacturer's latest documentation to confirm lead-free status and RoHS compliance requirements. Confirm that the SOIC-8 package dimensions match the target PCB footprint design constraints. Ensure the operating temperature range meets the environmental specifications of the final assembly application.
Selection Notes
Select this component when a dual comparator with wide voltage tolerance is required. It is suitable for applications needing CMOS or TTL output interfacing without additional level shifting. Consider the 1.3 µs response time for non-high-speed signaling tasks. Verify thermal management needs for the SOIC-8 package in enclosed environments.
Part Context
This part belongs to the LM193 series of dual differential comparators from Texas Instruments. It shares functional similarities with the LM393 but offers extended industrial temperature ratings and specific packaging options. The DRG4 designation indicates a tape-and-reel surface-mount configuration compliant with specific manufacturing standards.
Replacement Considerations
LM393DRG4: Dual comparator with similar functionality but different speed and temperature characteristics.
