VCC Positive Power Supply (Pin 15) This pin is normally tied to the + 5.0 V. VSS) / 2.

a 1.2 kΩ load resistor between Tx1 and Tx2. Attention must be set so as not to exceed this level when an external input is added to the DSI pin. A telephone line (600 Ω) is driven through an external 600 Ω resistor. In this case, the output level becomes about half of differential output. PIN.
