*1. The base terminal (D terminal) is connected to the output
transistor base. It is also connected to the control monolithic
IC. Do not, therefore, apply an external voltage in operation.
*2. SDH04 have two or three terminals of the same function (VB,
Out1, Out 2, GND). The terminals of the same function must be
shorted at a pattern near the product.

Note 1: A pull-down resistor (11 kΩ typ.) is connected to the IN terminal.
VOUT turns "L" when a high impedance is connected to the IN terminal in
series.
