SN74HCS09QDRQ1

Inverter Gates Overview

The SN74HCS09QDRQ1 is an automotive-grade quadruple 2-input positive-AND gate from Texas Instruments, part of the SN74HCS09-Q1 series. It features Schmitt-trigger inputs for noise immunity and open-drain outputs. The device operates within a supply voltage range of 2 V to 6 V and supports a wide operating temperature range from -40°C to +125°C. Packaged in a 14-pin SOIC (D) case, it is AEC-Q100 qualified for Grade 1 applications.

Inverter Gates Feature Summary

• AEC-Q100 qualified for automotive applications with Grade 1 temperature rating
• Schmitt-trigger inputs provide enhanced noise filtering capabilities
• Open-drain output configuration allows flexible interfacing

Inverter Gates Applications

• Automotive electronic control units
• Body electronics systems
• Industrial logic control interfaces

Inverter Gates Procurement Notes

Verify the specific suffix QDRQ1 matches the required SOIC-14 package and tape-and-reel orientation. Confirm AEC-Q100 Grade 1 qualification aligns with project reliability standards. Check RoHS compliance status against current regulatory requirements. Ensure the open-drain output type suits the target circuit pull-up configuration.

Inverter Gates Selection Notes

Select this component when automotive reliability and Schmitt-trigger input noise immunity are required. The open-drain output necessitates external pull-up resistors for high-level logic states. Verify that the 2 V to 6 V supply range covers the system's operational voltage window. Consider the SOIC-14 footprint constraints during PCB layout design.

Inverter Gates Part Context

This device belongs to the SN74HCS09-Q1 family of automotive logic gates. It complements other HCS-series components like the SN74HCS00QDRQ1 NAND gate by providing AND functionality with Schmitt-trigger characteristics. The QDRQ1 suffix denotes the specific SOIC-14 surface-mount package variant.

Inverter Gates Replacement Considerations

Direct substitutes include other SN74HCS09-Q1 variants with different packaging options such as SN74HCS09QDR or SN74HCS09PW. Cross-reference pinouts and electrical specifications to ensure compatibility with existing board designs.
