74LV1T126GWH

Overview

The Nexperia 74LV1T126GWH is a single supply translating buffer and line driver featuring three-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 facilitates up translation from 1.2 V to 5.0 V and down translation from 5.0 V to 1.8 V. Propagation delay ranges from 3.6 ns to 11.6 ns depending on load capacitance. Operating temperature spans -40 °C to +125 °C.

Feature Summary

• Single supply level translation supporting both up and down conversion between standard CMOS logic levels.
• Three-state output controlled by an enable input for bus line management.
• Five-volt tolerant inputs allowing direct interfacing with higher voltage sources.

Applications

• Portable electronic devices
• Personal computers and notebooks
• Industrial controller systems
• Telecommunications equipment

Procurement Notes

Verify the specific package variant matches the design requirement, as the GWH suffix denotes the TSSOP5 form factor. Confirm that the intended operating environment falls within the specified temperature range and voltage limits. Ensure proper handling procedures are followed due to the surface-mount nature of the component.

Selection Notes

Select this component when a single-channel translator is required for mixed-signal environments. It is suitable for connecting controllers or processors operating at different voltage domains. Consider the propagation delay specifications relative to the system clock speed and load capacitance requirements.

Part Context

This part belongs to the 74LV series of low-voltage CMOS logic devices manufactured by Nexperia. It provides a compact solution for signal buffering and level shifting in space-constrained applications. The device integrates robust ESD protection and latch-up performance exceeding industry standards.

Replacement Considerations

The 74LV1T126GXH serves as a parameter-equivalent substitute available in the X2SON5 package. Verify pin compatibility and thermal characteristics when transitioning between the TSSOP5 and leadless package types.
