SN74AHCT32QDRQ1

Overview

The SN74AHCT32QDRQ1 is a quadruple 2-input positive OR gate from the SN74AHCT32Q automotive logic series. It operates within a supply voltage range of 4.5 V to 5.5 V and features low output currents of 8 mA (low) and -8 mA (high). The device exhibits a propagation delay of 5.5 ns and functions reliably across an extended temperature range from -40°C to +125°C. Packaged in a TSSOP-14 surface-mount format, it holds AEC-Q100 qualification for automotive applications.

Feature Summary

• Automotive-grade reliability with AEC-Q100 qualification
• High-speed logic performance with 5.5 ns propagation delay
• Compatible with standard CMOS logic interfaces

Applications

• Automotive electronic control units
• Signal routing in vehicle networks
• Logic processing in harsh environment systems

Procurement Notes

Verify the specific suffix QDRQ1 against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with 5V-only power domains due to the AHCT input requirements. Confirm AEC-Q100 grade alignment with project reliability standards before finalizing procurement orders.

Selection Notes

Select this component when designing for automotive environments requiring robust OR logic functionality. The AHCT series ensures TTL-compatible inputs while maintaining CMOS noise immunity. Verify that the system power supply strictly adheres to the 4.5V minimum requirement to ensure proper switching thresholds and signal integrity.

Part Context

This part belongs to Texas Instruments' SN74AHC/AHCT family, designed for high-speed digital applications. The 'Q' designation indicates automotive qualification, while 'T32' specifies the quad 2-input OR gate function. The DRQ1 suffix identifies the TSSOP-14 package and reel packaging configuration.
