Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix 'ZC' against official documentation to confirm the commercial temperature range and Sn-Pb lead finish specifications. Ensure compatibility with existing PCB footprints for the 8-lead SOIC package. Confirm that the voltage levels match the target system requirements before procurement.

Translators, Level Shifters Selection Notes

Select this component when translating LVPECL sources to LVTTL destinations in space-constrained designs. It is suitable for applications requiring low power consumption and high-speed performance up to 275MHz. Verify that the commercial operating temperature range meets the environmental conditions of the intended application.

Translators, Level Shifters Part Context

This part belongs to the Precision Edge SY10/100ELT21L family of translators. The '100' designation indicates compatibility with positive ECL 100K logic levels, distinguishing it from the '10' variant which supports 10H levels. The ZC suffix denotes the commercial temperature range and specific packaging configuration.

Translators, Level Shifters FAQ

How does the device handle open input conditions?

Under open input conditions, the /D input is biased at a VCC/2 voltage level while the D input is pulled to ground, forcing the Q output low to provide added stability.

What is the function of the VBB pin?

The VBB pin serves as a reference output that allows for differential, single-ended, or AC-coupled interfaces to the device.
