74AHCT2G126DP,125

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHCT2G126DP,125 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 4.5 V to 5.5 V and accepts TTL input levels. The device provides symmetrical output impedance and balanced propagation delays. It is housed in an SOT505-2 TSSOP8 package with a body width of 3 mm. The component supports an operating temperature range from -40 °C to +125 °C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Overvoltage tolerant inputs allow operation as translators in mixed voltage environments
• High noise immunity with CMOS low power dissipation characteristics
• ESD protection exceeds 2000 V per HBM and 1000 V per CDM standards

Buffers, Drivers, Receivers, Transceivers Applications

• Translating signals between mixed voltage logic domains
• Driving high-capacitance or transmission line loads
• Isolating data lines via three-state control

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the AHCT series specification aligns with the system's TTL input requirements. Ensure the thermal derating limits for the TSSOP8 package are respected during design validation. Check for any recent product change notices affecting marking codes or assembly locations.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when TTL-compatible inputs are required alongside AHC speed performance. The TSSOP8 package offers a compact footprint suitable for space-constrained designs. Verify that the 4.5 V minimum supply voltage meets the target system rail specifications. Consider the overvoltage tolerance if interfacing with 5.5 V signals while powered at lower voltages.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Nexperia 74AHC/AHCT family of high-speed Si-gate CMOS devices. It shares functional similarities with the 74AHC2G126 but differs in input switching thresholds to support TTL compatibility. The DP suffix indicates the TSSOP8 plastic thin shrink small outline package. It is distinct from automotive qualified variants which carry specific Q100 designations.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74AHC2G126DP,125 serves as a compatible alternative if CMOS input levels are acceptable instead of TTL. Other Nexperia dual buffers in the same package may be considered if pinout compatibility is verified.
