74AHC126D-Q100,118

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHC126D-Q100,118 is a quad buffer and line driver featuring three-state outputs controlled by active-high output enable inputs (nOE). It operates within a supply voltage range of 2.0 V to 5.5 V and supports an input voltage up to 5.5 V. The device is qualified to AEC-Q100 Grade 1 standards for automotive applications. It functions reliably across ambient temperatures from -40 °C to +125 °C. Propagation delays are specified at 7.0 ns maximum under typical conditions with a 50 pF load at 5.5 V.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 standards
• Inputs accept voltages higher than the supply voltage (VCC)
• Balanced propagation delays with Schmitt-trigger action on all inputs
• ESD protection exceeding 2000 V via Human Body Model and 1000 V via Charged Device Model

Buffers, Drivers, Receivers, Transceivers Applications

• Automotive electronic systems requiring signal buffering
• Mixed voltage environments utilizing overvoltage tolerant inputs
• High-density circuit designs needing reliable data transmission

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required package type, as the D suffix indicates SO14 packaging. Confirm that the component meets the intended temperature range requirements for your application environment. Ensure compliance with relevant automotive quality standards if used in vehicle electronics. Check current availability through authorized distributors as stock levels fluctuate.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a quad buffer with three-state control is required for automotive or industrial use. The overvoltage tolerant inputs allow direct interfacing between different voltage domains without additional level shifting components. Consider the SO14 package dimensions for PCB layout constraints. Verify that the operating voltage range aligns with your system's power supply specifications.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AHC126-Q100 series, which includes variants like the AHCT version for TTL-level inputs. The 'D' designation specifically identifies the plastic small outline package (SO14) with a body width of 3.9 mm. Other package options include TSSOP14 and DHVQFN14 within the same functional family. The Q100 suffix denotes automotive qualification.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include other 74AHC126 variants from Nexperia such as the PW (TSSOP14) or BQ (DHVQFN14) package versions. Cross-manufacturer equivalents must be verified for pin compatibility and electrical characteristics. Ensure any replacement maintains the AEC-Q100 Grade 1 qualification if automotive reliability is required.
