Translators, Level Shifters Procurement Notes

Verify the specific suffix 'DTR2G' corresponds to the TSSOP-8 tape and reel packaging format as defined in the datasheet ordering information. Confirm that the component meets RoHS compliance standards and lead-free requirements. Ensure the operating temperature range of -40°C to +85°C aligns with your system's thermal design constraints before finalizing procurement.

Translators, Level Shifters Selection Notes

Select this component when interfacing ECL sources with TTL destinations requiring low power and small footprint. The 100 series variant offers temperature compensation, whereas the 10 series does not. Consider the TSSOP-8 package for space-constrained designs. Verify that the required supply voltages (+5V/-5V) are available in the target system architecture.

Translators, Level Shifters FAQ

What is the function of the VBB pin?

The VBB pin provides an internally generated reference voltage. It can be used as a switching reference for single-ended inputs or to rebias AC-coupled inputs.

How does the Q output behave if inputs are open?

The Q output will default HIGH if the inputs are left open or are below 1.3 V.
