Peripheral Circuit Example
Usage Notes
1. The microprocessor output ports are CMOS outputs, and must be used in the high, low, or open states.
2. We recommend using a value of about 60 k
for R1 and R2.
3. Voltages applied to the IN1 and IN2 pins must not exceed the range 0 to 6 V. Note that negative voltages can cause
the IC to operate incorrectly. Also, do not apply voltages to IN1 or IN2 when the V
CC
voltage is not applied.
4. To prevent the upper and lower output transistors from both being in the on state at the same time, when switching
the IN1 and IN2 values, always hold the input open for a brief period during the transition. We recommend holding
the open state for a few tens of microseconds.
5. A capacitor must be inserted between V
CC
and ground. We recommend that this capacitor have a value of at least
20 μF.
