SN74HCS86QDRQ1

Inverter Gates Overview

The SN74HCS86QDRQ1 is an automotive-grade quadruple 2-input exclusive-OR gate manufactured by Texas Instruments. It belongs to the HCS logic series and operates within a supply voltage range of 2 V to 6 V. The device features Schmitt-trigger inputs for noise immunity and provides push-pull outputs with a low-level output current of 7.8 mA and a high-level output current of -7.8 mA. It exhibits a propagation delay of 6 ns and functions reliably across an operating temperature range from -40°C to +125°C. The component is housed in a 14-pin SOIC package and holds AEC-Q100 qualification.

Inverter Gates Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for reliability
• Schmitt-trigger inputs provide enhanced noise filtering and signal integrity
• Wide operating voltage range supports flexible power supply designs
• Extended temperature rating ensures stable performance in harsh environments

Inverter Gates Applications

Inverter Gates Procurement Notes

Verify that the ordering suffix matches QDRQ1 to ensure the correct SOIC-14 package, tape-and-reel packaging, and automotive grade. Confirm the presence of the AEC-Q100 designation on the datasheet to validate automotive suitability. Check for RoHS compliance status as specified in the manufacturer's documentation. Ensure the part number corresponds exactly to the SN74HCS86 family to avoid functional mismatches with other logic gates.

Inverter Gates Selection Notes

Select this component when an exclusive-OR function is required for automotive systems. The HCS series offers lower power consumption compared to older logic families while maintaining high-speed performance. The Schmitt-trigger input characteristic makes it suitable for applications with slow-rising signals or significant noise. Verify that the 2 V to 6 V supply range aligns with the system's power architecture before integration.

Inverter Gates Part Context

This part is a member of the SN74HCSxxQxxxQ1 family, which integrates high-speed CMOS technology with automotive reliability requirements. The 'HCS' designation indicates the inclusion of Schmitt-trigger inputs, distinguishing it from standard HC series devices. The 'QDRQ1' suffix specifies the SOIC-14 package and automotive qualification. This family serves as a bridge between commercial performance and automotive durability standards.

Inverter Gates Replacement Considerations

Direct substitutes include other SN74HCS86 variants with different packages such as SN74HCS86PWQ1 (TSSOP) or SN74HCS86NSRQ1 (VSSOP). Cross-family replacements like SN74HC86 are not pin-compatible or feature-equivalent due to the absence of Schmitt triggers. Verify that any alternative maintains the same AEC-Q100 qualification level.
