74LV1T126GXH

Overview

The Nexperia 74LV1T126GXH is a single supply translating buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 1.6 V to 5.5 V, supporting CMOS levels at 1.8 V, 2.5 V, 3.3 V, and 5.0 V. The device facilitates both up translation (e.g., 1.8 V to 3.3 V) and down translation (e.g., 3.3 V to 1.8 V). It utilizes an X2SON-5 package with dimensions of 0.8 mm by 0.8 mm. Propagation delay reaches 3.6 ns at 5.0 V with a 30 pF load.

Feature Summary

• Supports bidirectional level translation between 1.8 V, 2.5 V, 3.3 V, and 5.0 V logic families
• Features five-volt tolerant inputs for safe interfacing across mixed voltage environments
• Provides three-state output control via the OE pin to prevent bus contention

Applications

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

Procurement Notes

Verify the specific ordering suffix 'H' corresponds to the required reel packaging configuration before finalizing procurement orders. Confirm that the X2SON-5 package variant matches the intended PCB footprint requirements. Ensure compliance with RoHS directives and check for any applicable REACH substance declarations relevant to the target market regulations.

Selection Notes

Select this component when a single-channel translator is required for mixed-voltage signal paths. The low input threshold allows operation with 1.8 V logic even when powered at 3.3 V. Verify that the maximum operating temperature of +125 °C meets the environmental constraints of the deployment location.

Part Context

This part belongs to the 74LV family of low-voltage CMOS logic devices manufactured by Nexperia. It serves as a specialized interface solution for bridging different voltage domains in digital circuits. The device is designed for surface-mount assembly, offering a compact form factor suitable for space-constrained printed circuit board layouts.

Replacement Considerations

The 74LV1T125GXH is documented as a parameter-equivalent substitute option.
