DESCRIPTION/ORDERING INFORMATION

bidirectional voltage-level translation (up-translation/down-translation) between low voltages (down to 0.9 V) and

be extended, without degradation of performance even during level shifting.

used to isolate two halves of a bus for voltage and capacitance.

The TCA9517A has two types of drivers—A-side drivers and B-side drivers. All inputs and I/Os are overvoltage

applications where a larger input logic low is required on the B-side.
