5. CUSTOM CODE
SC50462 has a total of 8 bits custom code (C0~C7). Custom Code Bits –C4 and C5 can be externally selected
using the C4 and C5 Terminals. The C4 and C5 pins are inversed; therefore, if the C4 and C5 terminals are
pulled HIGH, then the Custom Code Bits— C4 and C5 would have the Value(0,0). Likewise, when pulled LOW,
then C4 and C5 bits will be (1,1),The other Customs Code Bits,namely:C0~C3 and C6,C7 are fixed at (1,1,1,0)
and (1,0 ):
The waveform of bits are given below:
0.25/0.26ms
Bit "0"
1.00/1.05ms
Bit "1"
2.00/2.10ms
Note: Oscillator Frequency=480 or 455kHz

HANDLING MOS DEVICES:
Electrostatic charges can exist in many things. 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.
