74AHC2G125DP,125

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHC2G125DP,125 is a dual buffer and line driver featuring three-state outputs controlled by active-low output enable inputs (nOE). It operates within a supply voltage range of 2.0 V to 5.5 V and utilizes the TSSOP8 plastic thin shrink small outline package (SOT505-2). The device provides overvoltage tolerant inputs up to 5.5 V, allowing compatibility in mixed-voltage environments. It supports an ambient operating temperature from -40 °C to +125 °C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Symmetrical output impedance with balanced propagation delays
• High noise immunity and CMOS low power dissipation
• ESD protection exceeding 2000 V (HBM) and 1000 V (CDM)
• Latch-up performance exceeds 100 mA per JESD 78 Class II Level A

Buffers, Drivers, Receivers, Transceivers Applications

• Mixed voltage translation between different logic families
• Driving high-capacitance or transmission-line loads
• Bus-oriented communications systems requiring tri-state control

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DP,125' corresponds to the TSSOP8 (SOT505-2) package variant rather than the VSSOP8 version. Confirm that the required input switching levels match the 74AHC series specifications for your target application voltage. Ensure design safeguards account for the specified absolute maximum ratings to prevent permanent damage.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual non-inverting buffer with tri-state capability is required for signal integrity in mixed-voltage designs. The wide supply voltage range accommodates both 3.3 V and 5.0 V systems. Consider the TSSOP8 footprint constraints and verify thermal derating requirements if operating near the upper temperature limit.

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 the 74AHCT2G125 but differs in input switching thresholds, as the AHC variant uses CMOS levels while the AHCT variant uses TTL levels. Both share identical pinouts and electrical characteristics regarding output drive and timing.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74AHC2G125DC,125 serves as a direct functional substitute, differing only in the SOT765-1 (VSSOP8) package instead of the SOT505-2 (TSSOP8) package used by the DP variant.
