This device contains circuitry to protect the inputs against damage due to high static voltages or electric fields; however, it is advised that normal precautions be taken to avoid application of any voltage higher than maximum rated voltages to this highimpedance circuit. For proper operation it is recommended that Vin and Vout be constrained to the range VSS 3 (Vin or Vout) 3 VDD.




Description

The MC14497 is a PCM remote control transmitter realized in CMOS technology. Using a dualsingle (FSK/AM) frequency biphase modulation, the transmitter is designed to work with the MC3373 receiver. Information on the MC3373 can be found in the Motorola Linear and Interface Integrated Circuits book (DL128/D).

There is not a decoder device which is compatible with the MC14497. Typically, the decoding resides in MCU software.
• Both FSK/AM Modulation Selectable
• 62 Channels (Up to 62 Keys)
• Reference Oscillator Controlled by Inexpensive Ceramic Resonator: Maximum Frequency = 500 kHz
• Very Low Duty Cycle
• Very Low Standby Current: 50 A Maximum
• Infrared Transmission
• Selectable StartBit Polarity (AM Only)
• Shifted Key Mode Available
• Wide Operating Voltage Range: 4 to 10 V
• See Application Notes AN1016 and AN1203
