Pinout/Connection Diagram

mc145028p Circuit
The decoder IC7 cheeks the incoming pulse train for the correct address. If that address is present, the valid output terminal, pin 11, goes high for the 2 1/2-s duration of the transmitted pulse trains. When the valid output signal returns to a low state, timer lC8 is triggered into operation. The output terminal of IC8, pin 3, goes high for a time period of about 11 s, as determined by R22 and C35. That output, in turn, enables IC9, a timer configured as a 50-percent duty-cycle oscillator with a period of about 1/4 s. The output of IC9 drives a piezo buzzer, which produces an attention-getting audio signal that alerts the user that a door of the vehicle has been opened. Power to operate the receiver is obtained from a set of three AAA alkaline cells connected in series to produce 4.5 V. Current draw is only 3 mA during standby, so battery life will be in the hundreds of hours. IC10 is a voltage-detector IC that allows current to flow through LED2 when the battery voltage falls below 3 V. That alerts the user that battery replacement is necessary.
