Translators, Level Shifters Replacement Considerations

Check for SY55855VKI or SY55855VKITR variants. These share similar functionality but may differ in lead finish or tape-and-reel configuration. Verify package compatibility before substitution.

Translators, Level Shifters FAQ

How should unconnected inputs be handled?

Unconnected inputs appear as logic zeros due to internal biasing. For VCC > 3.0V, leave both inputs unconnected. For VCC ≤ 3.0V, connect the complement input to VCC.

What is the typical LVDS output swing?

The LVDS output specifies a typical differential swing of 350mV on a nominal 1.25V common mode voltage above ground.
