74AHC1G126GV,125

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHC1G126GV,125 is a single bus buffer and line driver featuring a three-state output. It operates within a supply voltage range of 2.0 V to 5.5 V and utilizes CMOS technology for low power dissipation. The device provides overvoltage tolerant inputs up to 5.5 V, enabling compatibility in mixed-voltage environments. It is housed in an SC-74A (SOT753) surface-mount package with five leads. The component supports ambient temperatures from -40 °C to +125 °C and includes ESD protection exceeding 2000 V (HBM).

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides symmetrical output impedance and balanced propagation delays.
• Features high noise immunity and CMOS low power dissipation characteristics.
• Includes latch-up performance exceeding 100 mA per JESD 78 Class II Level A standards.

Buffers, Drivers, Receivers, Transceivers Applications

• Mixed voltage translation between different logic families.
• Bus-oriented communications systems requiring signal buffering.
• Clock distribution circuits needing line driving capabilities.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix '125' against current Nexperia documentation to confirm packaging details such as reel size or tape specifications. Ensure the SC-74A package variant matches the intended PCB footprint requirements. Confirm RoHS compliance status directly with the manufacturer's latest product data sheet before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a single-channel buffer with three-state control is required for 5.5 V tolerant applications. The AHCT variant offers TTL input levels, whereas the AHC version uses CMOS levels; verify input logic compatibility. Consider the SC-74A package dimensions if space constraints are critical compared to other available package options like TSSOP5 or XSON.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Nexperia 74AHC/AHCT 1G series of single-gate logic devices. These components are designed for general-purpose digital applications requiring minimal board space. The 74AHC1G126 specifically functions as a non-inverting buffer with an active-low output enable pin, distinguishing it from inverters or multi-gate configurations within the same family.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct functional equivalents include the 74AHCT1G126GV,125 for TTL-compatible inputs. Other package variants such as 74AHC1G126GW (TSSOP5) offer identical electrical performance but require different footprints. Verify pinout compatibility when substituting with packages like SOT886 or SOT8065-1.
