VZ = 7V Zenor

• Use of Zenor diode in the range of Vz = 7V is recommended for surge protection.

• Installation of external capacitance is recommended between the power supply pin and GND in order to prevent

malfunction due to noise, etc.

• In the example given, terminal resistor is connected to the edge of transmission route in the transmission route

connection, but the method of connecting terminal resistor to each node is recommended. In this case, pay attention to

the total terminal resistance value of the transmission route.
