NOTES ON CORRECT USE

• No internal resistor is connected to input pins CTL1 (pin 4), CTL2 (pin 13), CTL3 (pin 5), and CTL4 (pin 12).

When using the

µPD16874, therefore, be sure to set the voltage level of these input pins to “H” or “L”.

• Keep the IN pins (pins 1 and 8) at the same potential.

supply voltage) (resistance: approx. 400 k

Ω). Therefore, no external pull-up resistor has to be connected to

these pins.
