SEMICONDUCTOR TECHNICAL DATA

P SUFFIX

PLASTIC DIP

CASE 707

The MC14497 is a PCM remote control transmitter realized in CMOS

technology. Using a dual–single (FSK/AM) frequency bi–phase 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).

ORDERING INFORMATION

MC14497P

Plastic DIP

There is not a decoder device which is compatible with the MC14497.

Typically, the decoding resides in MCU software.
