74AHC2G126DC-Q100H

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHC2G126DC-Q100H is a dual 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 ambient temperature range from -40 °C to +125 °C. The device utilizes a VSSOP8 plastic package (SOT765-1) with eight leads and a body width of 2.3 mm. Inputs are overvoltage tolerant up to 5.5 V, enabling use as translators in mixed-voltage environments. It meets AEC-Q100 Grade 1 qualification standards for automotive applications.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Automotive product qualification in accordance with AEC-Q100 (Grade 1)
• Overvoltage tolerant inputs allowing operation in mixed voltage environments
• Symmetrical output impedance with balanced propagation delays
• High noise immunity and CMOS low power dissipation

Buffers, Drivers, Receivers, Transceivers Applications

• Automotive electronic systems requiring qualified logic components
• Mixed voltage signal translation between different logic domains
• Buffering and driving high-capacitance loads in data lines

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix DC indicates the VSSOP8 package variant when sourcing. Confirm that the Q100 designation aligns with required automotive reliability standards. Ensure input voltage levels match the CMOS specifications for this specific part number rather than AHCT variants. Check datasheet revision history for any updates to electrical characteristics or marking codes before finalizing design-in.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual buffer with three-state capability is needed for automotive-grade designs. The VSSOP8 package offers a compact footprint suitable for space-constrained PCB layouts. Verify that the operating voltage range covers the system's lowest and highest supply rails. Consider the overvoltage tolerance if interfacing directly with 5 V signals while powered at lower voltages.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Nexperia 74AHC_AHCT2G126-Q100 family of dual buffers. It shares functional similarities with other members like the 74AHCT2G126DC-Q100 but differs in input switching levels. The family provides symmetrical output impedance and high noise immunity across various package options including TSSOP8 and VSSOP8.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74AHCT2G126DC-Q100 serves as a compatible alternative if TTL input levels are required instead of CMOS levels. Both parts share identical pinouts and package dimensions. Verify that the replacement meets the same AEC-Q100 Grade 1 qualification requirements for the target application.
