Translators, Level Shifters Procurement Notes

Verify the specific suffix 'E4' indicates lead-free compliance and environmental standards as defined by the manufacturer. Confirm the package type matches the required PCB footprint, specifically the 24-lead Thin Shrink Small Outline Package (TSSOP). Ensure the voltage requirements of the target application align with the specified VCCA and VCCB ranges before finalizing procurement.

Translators, Level Shifters Selection Notes

Select this component when bidirectional data transfer is required between circuits powered by different voltage rails, specifically where one side operates below 3.6 V and the other up to 5.5 V. Consider the propagation delay characteristics and output drive capabilities relative to the bus capacitance. Evaluate the physical package constraints to ensure compatibility with the intended surface-mount assembly process.
