74AHC2G126DP,125

Buffers, Drivers, Receivers, Transceivers Overview

The 74AHC2G126DP,125 is a dual buffer/line driver with 3-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 features overvoltage tolerant inputs up to 5.5 V. The device utilizes CMOS technology for low power dissipation and high noise immunity. It is specified for ambient temperatures from -40 °C to +125 °C and housed in an SOT505-2 (TSSOP8) package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Dual buffer/line driver configuration with independent 3-state outputs
• Overvoltage tolerant inputs allowing operation in mixed voltage environments
• Symmetrical output impedance with balanced propagation delays
• High ESD protection exceeding 2000 V HBM and 1000 V CDM

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual non-inverting buffer with 3-state control is required. Ensure the application voltage falls between 2.0 V and 5.5 V. Verify that the TSSOP8 package dimensions fit the PCB layout constraints. Confirm that the input signal levels are compatible with CMOS logic thresholds for the AHC variant.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Nexperia 74AHC family of high-speed Si-gate CMOS devices. It shares functional similarities with other 74AHC2G126 variants but differs in packaging. The DP suffix specifically denotes the TSSOP8 plastic thin shrink small outline package with an 8-lead configuration.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74AHC2G126DC,125 is listed as a similar alternative, utilizing a VSSOP8 package instead of TSSOP8. Verify pinout compatibility and physical footprint differences before substitution.
