Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm lead finish and packaging type. The 'KG' suffix indicates a Pb-Free package with a NiPdAu lead finish and a Pb-Free bar line indicator. Confirm whether the required quantity necessitates the tape and reel variant (ending in TR) or the tube variant. Ensure the design accounts for the specified humidity sensitivity classification during storage and assembly processes.

Translators, Level Shifters Selection Notes

Select this component when interfacing legacy high-speed ECL-family drivers with modern LVDS receivers. The device accommodates various supply voltages between 3.0V and 5.7V, facilitating level shifting without external biasing networks. Its compact 10-pin MSOP footprint is suitable for space-constrained PCB layouts. Designers must ensure proper termination of the 50-ohm impedance transmission lines to maintain signal integrity at speeds approaching 1.5Gbps.

Translators, Level Shifters Part Context

This part belongs to Micrel’s SuperLite family of high-speed logic devices, characterized by small packaging and operation at multiple supply voltages. While originally manufactured by Micrel, the product line is now managed under Microchip Technology following industry acquisitions. The SY55855 serves as a bridge between different voltage level standards, enabling interoperability between diverse high-speed communication protocols.

Translators, Level Shifters Replacement Considerations

The SY55855VKI is the tin-lead equivalent offering identical electrical performance but with a Sn-Pb lead finish. For direct pin-compatible substitution with different packaging options, verify the availability of the SY55855VKITR (tape and reel) or SY55855VKGTR variants based on manufacturing requirements.
