74AHC541BQ-Q100X

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHC541BQ-Q100X is an octal buffer and line driver featuring three-state outputs, designed for automotive applications. It operates within a supply voltage range of 2.0 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device includes two active-low output enable inputs (OE0 and OE1) and overvoltage tolerant inputs up to 5.5 V. Packaged in a DHVQFN20 (SOT764-1) format with side-wettable flanks, it meets AEC-Q100 Grade 1 qualification standards.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 Grade 1 standards
• Dual active-low output enables allowing independent control of data flow
• Overvoltage tolerant inputs facilitating operation in mixed-voltage environments
• DHVQFN package design enabling automatic optical inspection of solder joints

Buffers, Drivers, Receivers, Transceivers Applications

• Automotive electronic systems requiring robust logic buffering
• Mixed-voltage signal translation between different logic levels
• High-noise immunity digital circuit interfaces
• Octal data bus drivers in temperature-extreme environments

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'X' against manufacturer documentation to confirm reel packaging specifications. Ensure the DHVQFN20 footprint matches the SOT764-1 outline dimensions during PCB layout. Confirm that the design accounts for the thermal dissipation requirements associated with the exposed pad structure in this package type.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when automotive reliability under extreme temperatures is required. The AHC series offers balanced propagation delays and low power consumption suitable for high-speed applications. Verify input compatibility; standard AHC inputs require CMOS levels, whereas AHCT variants support TTL levels if necessary for legacy interfacing.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AHC541-Q100 family of octal buffers. It shares functional characteristics with other members like the 74AHCT541-Q100 but differs in input threshold requirements. The BQ designation specifically identifies the DHVQFN20 package variant, distinguishing it from SO20 or TSSOP20 versions within the same logical family.
