74AHC1G32QW5-7

Overview

The 74AHC1G32QW5-7 is an automotive-compliant single two-input positive OR gate manufactured by Diodes Incorporated. It operates within a supply voltage range of 2.0V to 5.5V and features standard push-pull outputs with ±8mA drive capability at 4.5V. The device incorporates Schmitt trigger action at all inputs, providing tolerance for slower input rise and fall times. It supports ambient temperature operation from -40°C to +125°C and includes ESD protection exceeding 2000V via the Human Body Model.

Feature Summary

• Automotive Grade 1 qualification compliant with AEC-Q100 standards
• Schmitt trigger inputs enhance circuit tolerance for slow signal transitions
• Balanced propagation delays and symmetric drive capabilities
• High ESD robustness exceeding 2000V HBM and 1000V CDM

Applications

• Automotive applications requiring specific change control
• Industrial computing and automation controls
• High reliability networking and communications systems
• Industrial and agricultural equipment logic circuits

Procurement Notes

Verify that the ordering suffix W5 corresponds specifically to the SOT25 package variant. Confirm the -7 suffix indicates tape and reel packaging containing 3000 units per reel. Ensure the component meets IATF 16949 manufacturing requirements if PPAP documentation is required for your specific supply chain integration.

Selection Notes

Select this component when a single OR gate function is required in space-constrained designs utilizing the SOT25 footprint. It is appropriate for systems needing wide voltage compatibility between 2.0V and 5.5V. The inclusion of Schmitt triggers makes it suitable for noisy environments or signals with gradual transition edges.

Part Context

This part belongs to the 74AHC1GxxQ series of automotive-grade logic devices from Diodes Incorporated. The 'Q' designation signifies compliance with AEC-Q100 standards, while the '1G' indicates a single-gate configuration. The series is designed for general-purpose logic applications requiring high reliability and broad operating temperature ranges.

Replacement Considerations

Cross-reference with other 74AHC1G32 variants from different manufacturers. Verify pinout compatibility and ensure the replacement device matches the SOT25 package dimensions and electrical characteristics, particularly output drive current and propagation delay specifications.

FAQ

What is the maximum input voltage allowed for this device?

The absolute maximum rating for the input voltage (VI) is 6.5V, although the recommended operating voltage range is limited to the VCC supply range of 2.0V to 5.5V.

Does the device require termination for unused inputs?

Yes, unused inputs should be held at either VCC or Ground to prevent undefined states and excessive power consumption.
