LM193DR

Overview

The LM193DR is a dual differential analog comparator manufactured by Texas Instruments, housed in an 8-SOIC surface-mount package. It features open-collector outputs compatible with CMOS and TTL logic families. The device operates on a single supply voltage ranging from 2V to 36V or dual supplies of ±1V to ±18V. Key electrical specifications include a maximum input offset voltage of 5mV at 30V, a typical response time of 1.3μs, and a maximum static supply current of 2.5mA. The component supports a wide operating temperature range from -55°C to 125°C.

Feature Summary

• Dual-channel differential comparison capability within a compact SOIC-8 footprint
• Open-collector output structure enabling flexible interfacing with various logic standards
• Wide single or dual power supply voltage tolerance for diverse system architectures

Applications

• Over-voltage and under-voltage detection circuits
• Threshold sensing and level detection applications
• Simple delay and timing circuit implementations

Procurement Notes

Verify the specific suffix 'DR' confirms the tape-and-reel packaging format and SOIC-8 body style. Ensure the manufacturer designation matches Texas Instruments to distinguish from other vendors producing equivalent LM193 variants. Confirm RoHS compliance status and check for any recent production lifecycle notices regarding availability or assembly site changes before finalizing procurement orders.

Selection Notes

Select this component when a low-cost, general-purpose dual comparator is required for basic threshold detection tasks. It is suitable for designs where moderate speed is acceptable and open-collector outputs align with the system's pull-up requirements. Consider alternative packages if higher pin counts or different thermal performance are needed for the specific application constraints.

Part Context

This part belongs to the LM193 family of low-power, low-offset voltage dual comparators. It shares functional similarities with the LM293 and LM393 series but offers an extended industrial temperature range down to -55°C. The device serves as a fundamental building block for analog signal processing and control systems requiring reliable voltage comparison.

Replacement Considerations

LM293DR and LM393DR are functionally similar dual comparifiers from Texas Instruments. Verify that the replacement part meets the -55°C to 125°C temperature range requirement and maintains compatibility with the existing open-collector output configuration.
