Note: when are connected to the Vss SEL, D7 = 1; SEL when connected to VDD, D7 = 0.

Typical application circuit diagram

Note: 1. The power supply side two capacitance must be close to the circuit.

      2. The two power supply and ground connection capacitance and short.

PCB wiring diagram:

Used in the above figure IC is only used to hint, not.

Remote control board layout considerations:

* note when wiring, power filtering capacitor close to the IC

* walk in the power line, should avoid to power supply, ground line is too long

* suggest infrared emission part and the power of the IC, ground should be off the line, and line add thick

* triode emitter requires at least 1 Ω resistance

* 9014 is recommended for triode

Packaging appearance figure

MOS circuits operating considerations:

  Will generate static electricity in many places, take the following measures,

can effectively prevent the MOS circuit due to the effect of electrostatic

discharge damage caused by:

 operators to grounding through the anti-static wrist strap.

 equipment enclosure must be grounded.

 tools used in the assembly process must be grounded.

 must use conductive antistatic packaging or material packaging or transportation.
