Translators, Level Shifters Procurement Notes

Verify the specific suffix DTG corresponds to the TSSOP-8 package configuration when sourcing. Confirm RoHS compliance and lead-free status as indicated by the G suffix in ordering information. Ensure the application environment remains within the specified -40°C to +85°C operating temperature range for guaranteed performance.

Translators, Level Shifters Selection Notes

Select this component when interfacing differential high-speed signals with standard low-voltage logic families. The device simplifies design by eliminating the need for negative power supplies. Consider the TSSOP-8 package dimensions if board space is constrained. Verify that the input voltage swing meets the minimum requirements for reliable switching at the target frequency.

Translators, Level Shifters FAQ

How should the VBB pin be utilized?

The VBB pin provides an internal reference voltage. It can be tied to the D input for single-ended capacitive coupling or connected through resistors to both inputs for differential capacitive coupling.

What is the required power supply configuration?

The device requires only a positive 3.3 V supply (VCC) and Ground (GND). No negative voltage rail is necessary for operation.
