74AHCT1G32QSE-7

Overview

The 74AHCT1G32QSE-7 is a single 2-input positive OR gate from the AHCT logic family, manufactured by Diodes Incorporated. It operates within a supply voltage range of 4.5V to 5.5V and features standard push-pull outputs with ±8mA drive capability at 5.0V. The device is housed in an SOT-353 package and supports ambient temperature operation from -40°C to +125°C. Propagation delay is specified as 4.8ns typical at 5V with 50pF load. It includes Schmitt trigger inputs for noise tolerance and meets AEC-Q100 Grade 1 qualification standards.

Feature Summary

• AEC-Q100 qualified for automotive applications requiring specific change control
• Schmitt trigger action on all inputs to tolerate slower rise and fall times
• CMOS low-power consumption design
• ESD protection exceeding 2000V Human Body Model and 1000V Charged Device Model

Applications

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

Procurement Notes

Verify that the component matches the exact part number 74AHCT1G32QSE-7, specifically confirming the SE suffix indicates the SOT-353 package. Ensure the Q suffix confirms AEC-Q100 automotive qualification. Check datasheet revision DS41464 Rev. 1-2 for accurate electrical characteristics. Confirm RoHS compliance status if required by project specifications.

Selection Notes

Select this component when a single 2-input OR function is required in a 5V logic environment. The AHCT series ensures compatibility with TTL input levels while maintaining CMOS output performance. The SOT-353 package is suitable for space-constrained surface mount designs. Verify that the operating voltage remains strictly between 4.5V and 5.5V to ensure proper functionality.

Part Context

This device belongs to the 74AHCT1GxxQ series of single-function gates designed for automotive use. It shares the same package and basic electrical profile as other members like the 74AHCT1G02QSE-7 (NAND) or 74AHCT1G86QSE-7 (XOR). The 'Q' designation signifies automotive-grade manufacturing in IATF 16949 certified facilities.

Replacement Considerations

The 74AHCT1G32QW5-7 serves as a direct functional substitute using the SOT-25 package instead of SOT-353. Other 74AHCT1Gxx devices may replace it only if the logical function matches the circuit requirements.

FAQ

What is the Boolean function performed by this gate?

The device performs the positive Boolean function Y = A + B.

Are unused inputs allowed to float?

No, unused inputs should be held at VCC or Ground to prevent undefined states.
