74LV1T126GVH

Overview

The Nexperia 74LV1T126GVH is a single supply translating buffer and line driver featuring 3-state outputs. It supports voltage levels of 1.8 V, 2.5 V, 3.3 V, and 5.0 V with a supply voltage range of 1.6 V to 5.5 V. The device enables up translation from 1.2 V to 5.0 V and down translation from 3.3 V or 5.0 V to lower voltages. Propagation delay ranges from 3.2 ns to 9.6 ns depending on load capacitance and supply voltage. Operating temperature spans -40 °C to +125 °C.

Feature Summary

• Supports bidirectional level translation between 1.2 V and 5.0 V using a single supply
• Features 5 V tolerant inputs for safe interfacing across mixed voltage domains
• Provides controlled 3-state output via an active LOW enable input

Applications

• Portable applications
• PC and notebook systems
• Industrial controllers
• Telecom equipment

Procurement Notes

Verify the specific suffix 'H' against official Nexperia documentation to confirm tape and reel packaging specifications. Confirm that the SC-74A package variant matches the required footprint. Ensure the operating temperature range meets system requirements before finalizing procurement orders.

Selection Notes

Select this component when a single-channel translator is needed for mixed-voltage interfaces. It is suitable for connecting 1.8 V logic to 3.3 V or 5.0 V buses. Consider the propagation delay limits at maximum load capacitance. Verify that the 3-state control logic aligns with the system bus architecture.

Part Context

This part belongs to the 74LV family of low-voltage CMOS logic devices. It functions as a unidirectional buffer with level-shifting capabilities. The device is designed for high-speed data transmission in environments requiring voltage domain isolation. It complements other Nexperia translators like the 74LVC2T45 for bi-directional needs.

Replacement Considerations

Check for direct substitutes such as the 74LV1T126GW or 74LV1T126GX if package variations are acceptable. Verify pin compatibility and electrical characteristics against alternative single-buffer translators.
