If the IC 9 decorder (TC4028BP) received signals from MICOM pins (3 6), an output signal per 2 miliseconds comes out from Q3, Q41, Q8, Q6, Q9, Q7, Q0, Q2, and Q4 pin in sequence.
  • Page 79 11. CIRCUIT DESCRIPTIONS The step signals of DC 11 12V will be generated periodically. If a sink signal outputs from IC4, DC 11-12V will be applied to the LED input terminal and sink the LED output terminal to 0V. Therefore, LED will be ON for 2 miliseconds. 2) Key Scan The 6 step signals, Q6 Q4 are applied to scan the 6 keys (buttons).
