74AHC125BQ-Q100,11

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHC125BQ-Q100,11 is a quad buffer and line driver featuring three-state outputs controlled by active-low output enable inputs. It operates within a supply voltage range of 2.0 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device utilizes a DHVQFN14 package (SOT762-1) with dimensions of 2.5 mm x 3 mm x 0.85 mm. Inputs are overvoltage tolerant up to 5.5 V, enabling use in mixed-voltage environments.

• Automotive qualification compliant with AEC-Q100 Grade 1 standards for automotive applications
• Overvoltage tolerant inputs allowing operation in mixed voltage environments
• Schmitt-trigger action on all inputs for high noise immunity
• DHVQFN package with side-wettable flanks supporting automated optical inspection

Buffers, Drivers, Receivers, Transceivers Applications

• Automotive electronic systems requiring qualified logic components
• Mixed voltage signal translation between different logic levels
• High-speed data bus buffering and line driving
• Applications demanding low power CMOS dissipation

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix BQ corresponds to the DHVQFN14 package configuration required for your design. Confirm that the Q100 designation aligns with your automotive grade requirements. Ensure input voltage tolerances match your system's maximum operating levels. Check thermal derating curves for total power dissipation limits at elevated temperatures.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a quad buffer with independent three-state control is needed in a compact footprint. The DHVQFN14 package offers a small body size suitable for space-constrained PCB layouts. Consider the overvoltage tolerance if interfacing directly with higher voltage nodes without level shifting circuitry.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AHC125-Q100 family of quad buffers. The BQ suffix specifically identifies the DHVQFN14 plastic dual in-line compatible thermal enhanced very thin quad flat package variant. Other variants in the series include SO14 and TSSOP14 packages.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include other 74AHC125 devices in equivalent packages. Verify pinout compatibility and electrical characteristics before substitution. Cross-reference with manufacturer databases for alternative package options within the same logic family.
