MC14497 PCM Remote Control Transmitter

E1 * E8 Row Inputs (Pins 1, 2, 10, 11, 14, 15, 16, 17) Under idle conditions, these inputs are held high by internal pull *up resistors. As soon as a key is pressed, a logical 0 on that particular line signals to the circuit that a key has been selected. After a delay of 20 ms, the i.

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MC14497/D PCM Remote Control Transmitter 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). There is not a decoder device which is compatible with the MC14497. T.

MC14497 Features

* is its low power consumption (in the order of 10 µA in the idle state). For this reason, the battery is perpetually in circuit. It has in fact been found that a light discharge current is beneficial to battery life. In its active state, the transmitter efficiency is increased by the use of a low dut
