74LV1T34GWH

Overview

The Nexperia 74LV1T34GWH is a single supply translating buffer housed in a TSSOP5 (SOT353-1) package. It operates within a supply voltage range of 1.6 V to 5.5 V, supporting logic levels at 1.8 V, 2.5 V, 3.3 V, and 5.0 V. The device features 5 V tolerant inputs and provides up translation from lower voltages such as 1.2 V to 1.8 V or 3.3 V to 5.0 V, as well as down translation capabilities. Static characteristics include an input leakage current of ±1 µA maximum and a supply current of 10 µA maximum. Dynamic performance specifies propagation delays ranging from 3.9 ns to 11.4 ns depending on load capacitance and supply voltage.

Feature Summary

• Supports both up translation and down translation between various CMOS logic levels
• Features 5 V tolerant inputs for interfacing with higher voltage systems
• Provides latch-up protection exceeding 250 mA per JESD 78 Class II

Applications

• Portable applications
• PC and notebooks
• Industrial controller
• Telecom

Procurement Notes

Verify the specific ordering suffix 'H' corresponds to the tape and reel packaging configuration required for automated assembly processes. Confirm that the TSSOP5 package dimensions align with the target PCB footprint and soldering profile specifications. Ensure compliance with RoHS directives and REACH regulations by checking the most recent product change notifications issued by Nexperia prior to finalizing procurement orders.

Selection Notes

Select this component when a single-channel non-inverting buffer is required to bridge different voltage domains within mixed-signal designs. The wide operating temperature range supports deployment in harsh industrial environments. Evaluate the propagation delay specifications against system timing requirements to ensure signal integrity is maintained across the translation interface without introducing excessive latency.

Part Context

This part belongs to the 74LV series of low-voltage CMOS logic devices manufactured by Nexperia. It functions specifically as a level translator rather than a standard logic gate. The GWH designation identifies the specific plastic thin shrink small outline package variant designed for surface-mount technology applications requiring compact board space utilization.

Replacement Considerations

Direct replacements include the 74LV1T34GV and 74LV1T34GX variants, which share identical electrical specifications but utilize SC-74A and X2SON5 packages respectively.
