74AHC1G09QW5-7

Overview

The 74AHC1G09QW5-7 is an automotive-compliant, single two-input positive AND gate with an open drain output. It operates within a supply voltage range of 2.0V to 5.5V and supports Grade 1 ambient temperature operation from -40°C to +125°C. The device features Schmitt trigger inputs for tolerance to slower rise and fall times, balanced propagation delays, and ESD protection exceeding 2000-V Human Body Model and 1000-V Charged Device Model per AEC-Q100 standards.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 standards
• Open drain output architecture requiring external pull-up resistor
• Schmitt trigger action at all inputs for improved noise immunity
• High ESD protection capability exceeding standard industrial thresholds

Applications

• Automotive applications within Grade 1 temperature range
• Industrial computing, controls, and automation systems
• High-reliability networking and communications equipment
• Industrial and agricultural machinery logic circuits

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the Q series includes both SOT25 and SOT353 variants. Confirm that the open drain output configuration aligns with the target circuit design, as a pull-up resistor is mandatory for high-state operation. Ensure the application environment remains within the specified -40°C to +125°C operating range to maintain guaranteed electrical characteristics.

Selection Notes

Select this component when an AND function with open drain capability is required in space-constrained designs. The AHC family offers low power consumption suitable for battery-operated or efficiency-critical systems. Verify input voltage levels against the recommended operating conditions table to ensure proper logic threshold compliance across the entire supply voltage range.

Part Context

This part belongs to the Diodes Incorporated 74AHC1G09Q automotive logic family. It provides a single two-input AND gate in a compact surface-mount package. The Q suffix indicates AEC-Q100 qualification and PPAP capability, distinguishing it from standard commercial grade devices. It serves as a specialized solution for automotive and high-reliability industrial environments requiring robust performance under varying thermal conditions.

Replacement Considerations

Direct substitutes include other AEC-Q100 qualified single AND gates with open drain outputs from the same manufacturer, such as the 74AHC1G09QSE-7 (SOT353 package). Cross-manufacturer replacements must match the open drain topology and verify compatible input/output voltage thresholds.
