74AHCT541BQ,115

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHCT541BQ,115 is an octal buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 2.0 V to 5.5 V and utilizes TTL input levels for the AHCT variant. The device includes two active LOW output enable inputs (OE0 and OE1) that force associated outputs into a high-impedance OFF-state when HIGH. Inputs are overvoltage tolerant up to 5.5 V, enabling use in mixed-voltage environments. It is housed in a DHVQFN20 package (SOT764-1) with dimensions of 2.5 mm x 4.5 mm x 0.85 mm.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and lead-free material declarations prior to integration. Ensure design-in reviews account for the thermal pad requirements of the DHVQFN20 package as detailed in the datasheet pinning information.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when TTL-compatible input thresholds are required alongside CMOS drive capabilities. The dual output enable pins allow flexible control of data flow direction or bus isolation. Verify that the application load capacitance falls within the dynamic characteristics limits to ensure signal integrity and timing accuracy during operation.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AHC/AHCT logic family, designed for high-speed digital applications. The 'BQ' suffix denotes the DHVQFN20 leadless package, while '115' indicates the standard reel quantity packaging configuration. It serves as a non-inverting buffer solution for systems requiring robust signal driving and electrical isolation.

Buffers, Drivers, Receivers, Transceivers FAQ

How do the output enable inputs function?

Both OE0 and OE1 are active LOW. If either input is HIGH, the corresponding outputs enter a high-impedance OFF-state regardless of the input data levels.

What is the input voltage tolerance?

The inputs are overvoltage tolerant up to 5.5 V, allowing them to interface with 5 V logic even if the device is powered at lower voltages within the specified range.
