SN74AHCT02QPWRQ1

Overview

The SN74AHCT02QPWRQ1 is an automotive-grade quadruple 2-input positive-NOR gate from Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a temperature range of -40°C to +125°C. The device features TTL-compatible CMOS inputs and balanced push-pull outputs capable of ±8 mA drive current at 5 V. Propagation delays are specified between 1 ns and 8.5 ns depending on load capacitance. It includes AEC-Q100 qualification, HBM ESD Level 2, and CDM Level C4B ratings.

Feature Summary

• AEC-Q100 qualified for automotive applications with extended temperature support
• TTL-voltage compatible inputs for direct interfacing with legacy logic
• Balanced CMOS push-pull outputs providing symmetric source and sink capabilities
• Wettable flank QFN package option available to facilitate automatic optical inspection

Applications

• Enabling or disabling digital signals in control circuits
• Controlling indicator LEDs via latch configurations
• Voltage translation between communication modules and system controllers

Procurement Notes

Verify the specific package suffix (PW for TSSOP or BQA for WQFN) matches the target PCB footprint. Confirm the 'Q1' designation aligns with automotive reliability requirements. Check the latest orderable addendum for moisture sensitivity levels and reflow temperature profiles. Ensure unused inputs are terminated to prevent undefined states during operation.

Selection Notes

Select this component when a NOR function is required in a 5 V automotive environment. The AHCT series is appropriate for systems needing TTL input compatibility. Consider the BQA package if board space is limited and AOI inspection is mandatory. Verify that the 50 pF capacitive load limit meets the downstream circuit requirements.

Part Context

This part belongs to the SN74AHCT02-Q1 family of single-function gates. It provides four independent NOR gates in a compact surface-mount form factor. The device is designed for high-reliability automotive electronics where stable performance across wide temperature variations is critical. It complements other logic families like AHC and ACT within the same product portfolio.
