The above IC only use to hint, not to specified. Note: * In wire layout, the power filter capacitor should near to IC. * In wire layout, should avoid power line and ground line too long. * Recommended infrared transmit unit and IC ground line should layout separated, or over striking lines. * The emitter of triode connect 1 resistor at least. * Recommended triode use 9014.

All of our MOS devices are internally protected against electrostatic discharge but they can be damaged if the following precautions are not taken: • Persons at a work bench should be earthed via a wrist strap. • Equipment cases should be earthed. • All tools used during assembly, including soldering tools and solder baths, must be earthed. • MOS devices should be packed for dispatch in antistatic/conductive containers. Note: IC oscillator input mustn't be on the outside layer, thus to avoid the abnormal working when human body touches the remote controller without crust in testing.
