74AHC1G126GW-Q100H

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHC1G126GW-Q100H is a single non-inverting bus buffer and line driver featuring three-state outputs, housed in a TSSOP5 (SOT353-1) package. 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 meets AEC-Q100 Grade 1 qualification for automotive applications, functioning reliably from -40 °C to +125 °C. Static characteristics include high-level output current capability of -8 mA and low-level output current of 8 mA at VCC = 4.5 V. Dynamic performance specifies propagation delays (tpd) with a maximum of 9.5 ns at VCC = 5.5 V and CL = 50 pF.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 standards for reliability in vehicle environments.
• Overvoltage tolerant inputs allow safe interfacing with signals exceeding the supply voltage level.
• Three-state output controlled by an enable pin to prevent bus contention during inactive periods.
• CMOS technology provides symmetrical output impedance and balanced propagation delays.

Buffers, Drivers, Receivers, Transceivers Applications

• Automotive electronic systems requiring robust signal buffering
• Mixed-voltage environment translation between different logic families
• High-speed data bus drivers in consumer electronics

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'H' against the manufacturer's official ordering information to confirm packaging details such as reel or cut tape specifications. Ensure the component matches the exact AHC logic family variant rather than the AHCT version, as input switching levels differ significantly between CMOS and TTL-compatible types. Cross-reference the marking code 'AN' on the physical device to validate authenticity and correct revision status.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a single-channel buffer with high noise immunity and wide supply voltage flexibility is required. The AHC series offers faster switching speeds compared to standard HC devices while maintaining low power consumption. Consider the overvoltage tolerance feature if the input source operates at voltages higher than the system's VCC rail without external protection components.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Nexperia 74AHC1G126-Q100 family of single-buffer line drivers. It shares functional similarities with other members like the 74AHCT1G126 but differs in input threshold requirements. The GW suffix specifically denotes the TSSOP5 plastic thin shrink small outline package, distinguishing it from SC-74A or XSON5 variants within the same logical family.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74AHCT1G126GW-Q100H serves as a direct functional substitute if the application requires TTL-compatible input levels instead of CMOS levels. Other single-buffer alternatives within the same package may be considered if electrical parameters align with the design requirements.
