SN74HCS14QDYYRQ1

Inverter Gates Overview

The SN74HCS14QDYYRQ1 is an automotive-grade hex inverter with Schmitt-trigger inputs, part of the HCS logic family. It operates within a supply voltage range of 2V to 6V and supports an ambient temperature range from -40°C to +125°C. The device features balanced CMOS push-pull outputs capable of ±7.8mA drive current at 6V. Propagation delay ranges from 5ns to 15ns depending on voltage. It includes typical supply current of 100nA and input leakage of ±100nA.

Inverter Gates Feature Summary

• Schmitt-trigger inputs provide hysteresis for noise rejection and tolerance to slow signals
• Balanced CMOS push-pull outputs ensure similar sourcing and sinking capabilities
• Low power consumption with minimal static supply current
• AEC-Q100 qualified for automotive reliability standards

Inverter Gates Applications

• Synchronize inverted clock inputs
• Debounce mechanical switches
• Invert digital signals

Inverter Gates Procurement Notes

Verify the specific ordering suffix matches the required package type, as the DYY suffix denotes SOT-23-THIN packaging. Confirm AEC-Q100 qualification requirements align with target automotive applications. Ensure design accounts for thermal resistance values specific to the selected package variant during layout planning.

Inverter Gates Selection Notes

Select this component when low power operation and noise immunity are critical. The wide voltage range suits various automotive power rails. Verify that the propagation delay meets timing constraints for the specific application frequency. Consider the SOT-23-THIN package size if board space is limited compared to standard SOIC or TSSOP options.

Inverter Gates Part Context

This device belongs to Texas Instruments' SN74HCS series, designed for high-speed CMOS automotive applications. It complements other logic families by offering Schmitt-trigger functionality with lower power consumption than standard HC devices. The Q1 designation indicates automotive grade qualification.

Inverter Gates Replacement Considerations

Check for SN74HCS14PW-Q1 (TSSOP) or SN74HCS14D-Q1 (SOIC) if different pinout compatibility is needed. Verify functional equivalence for non-automotive environments where AEC-Q100 is not required.
