TS393DR2G

Overview

The TS393DR2G is a dual micro-power CMOS voltage comparator manufactured by onsemi. It operates within a supply voltage range of 2.7 V to 16 V and draws a typical operating current of 6 µA. The device features an open-drain output capable of sourcing up to 20 mA per channel, ensuring compatibility with various logic families. Key electrical specifications include a maximum propagation delay of 5.8 µs, an input offset voltage of 1.4 mV, and an input bias current of 1 pA. It provides a common-mode rejection ratio of 71 dB and a power-supply rejection ratio of 80 dB. The component is housed in an 8-SOIC package and supports an extended operating temperature range from -40°C to +125°C.

Feature Summary

• Micro-power CMOS architecture designed for low energy consumption applications
• Open-drain output configuration compatible with TTL, CMOS, and other logic levels
• Extended industrial temperature rating suitable for harsh environments

Applications

• Battery-powered portable devices requiring ultra-low quiescent current
• Threshold detection circuits in consumer electronics

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to procurement. Ensure the selected variant matches the required SOIC-8 package dimensions and pinout configuration for your PCB layout.

Selection Notes

Select this component when design constraints demand minimal static power dissipation alongside standard general-purpose comparison functionality. The CMOS input structure offers significantly lower bias currents compared to bipolar alternatives, making it ideal for high-impedance sensor interfaces. Evaluate the 5.8 µs response time against system speed requirements to ensure adequate performance margins for the intended signal frequencies.

Part Context

This part belongs to the TS393 series of dual comparators, representing onsemi's micro-power CMOS line. It serves as a low-power alternative to traditional bipolar comparators like the LM393, offering reduced current drain while maintaining comparable output drive capabilities. The DR2G suffix indicates surface-mount availability in the SOIC-8 package format.

Replacement Considerations

The NCV2393 is a documented automotive-grade equivalent within the same family. Verify functional compatibility regarding pinout and electrical characteristics before substitution.
