TX Disable Control
The DIS pin is used to disable the transmit signal (both the modulation and bias current are disabled when DIS =
high).
The DIS input is compatible with TTL levels regardless of whether VCC = 5V or VCC = 3.3V. The external 4.7kΩ
and 10kΩ pull-up resistor required by most interface standards is not needed because this pin has an internal 7kΩ
resistor to V_CC.
