small signal product circuit board layout recommendations to protect data lines and the power line, connect pin 5 directly to the vdd. in this configuration the data lines are referenc ed to the supply voltage. the internal t vs diode prevents over-voltage on the supply rail. the tesds5v0a can be isolated from the power supply by adding a series resistor between pin 5 and vdd. a value of 100k ? is recommended. the internal tvs and steering diodes re main biased, providing the advantage of lower capacitance. in applications where no positive supply reference is available, or complete supply isolation is desired, the internal tvs may be used as the reference. in this case, pin 5 is not connected. the steering diodes will begin to conduct when the voltage on the protected line exceeds the working voltage of the tvs (plus one diode drop). document number: ds_s1501025 version: d15 data line protection using internal tvs diode as reference data line and power supply protection using vcc as referenc e data line protection with bias and power supply isolation tesds5v0 a taiwan semiconductor
