NCS2250SQ2T2G

Comparators Overview

The NCS2250SQ2T2G is a single-channel high-speed analog comparator manufactured by onsemi, housed in an SC-88A (SC70-5) surface-mount package. It features a complementary push-pull output stage and operates within a supply voltage range of 1.8 V to 5.5 V. The device exhibits a typical quiescent supply current of 150 μA at a 5 V supply. Key electrical characteristics include a propagation delay of 50 ns with 100 mV overdrive, an input offset voltage of 6 mV maximum, and a common mode rejection ratio of 81 dB. The rail-to-rail input allows signals 200 mV beyond the supply rails.

Comparators Feature Summary

• Features a complementary push-pull output stage for direct drive capability without external pull-up resistors.
• Provides rail-to-rail input operation extending 200 mV above and below the supply rails for ground or supply sensing.
• Delivers fast response times with a propagation delay of 50 ns under standard test conditions.

Comparators Applications

• Voltage threshold detection circuits
• Zero-crossing detectors
• High-speed sampling circuits
• Logic level shifting and translation
• Clock and data signal restoration

Comparators Procurement Notes

Verify the specific ordering suffix SQ2T2G corresponds to the SC-88A package and push-pull output configuration. Confirm that the component meets AEC-Q100 qualification requirements if intended for automotive end products. Ensure compliance with RoHS standards and lead-free packaging specifications as defined in the manufacturer's documentation.

Comparators Selection Notes

Select this component when a single-channel comparator with rail-to-rail inputs and a push-pull output is required. It is suitable for applications needing fast propagation delays around 50 ns and low power consumption near 150 μA. Consider alternative packages like TSOP-5 if space constraints differ, or the NCS2252 variant if an open-drain output is preferred.

Comparators Part Context

This part belongs to the NCS2250/NCS2252 family of low-voltage comparators from onsemi. The series includes variants with either push-pull outputs (NCS2250) or open-drain outputs (NCS2252). Both types are available in TSOP-5 and SC-88A packages, with automotive-grade options denoted by the NCV prefix.

Comparators Replacement Considerations

Direct functional substitutes within the same family include NCS2250SN2T1G, which offers identical performance in a TSOP-5 package. Automotive qualified equivalents are available as NCV2250SQ2T2G and NCV2250SN2T1G.

Comparators FAQ

What is the input common mode voltage range?

The input common mode voltage range extends from VSS - 0.2 V to VDD + 0.2 V, allowing sensing at ground or the supply voltage.

Does the NCS2250 require an external pull-up resistor?

No, the NCS2250 features a complementary push-pull output stage that does not require an external pull-up resistor.
