all or none of the 8 address bits (A0-A7) may be used.Settings of the Receiver and
Transmitter must match for signal to be recognized.
matched.
These outputs will go high as the corresponding buttons are pushed at the
transmitter. They can be interfaced directly with a microprocessor or used to turn on
and off LED’s, buzzers, etc., (Holtek chips can only sink/source 1mA on output pins
so external components may require a driving transistor.)
This is an example of a basic remote control design utilizing Holtek

transmitter, a corresponding pin at the receiver goes high.This basic circuit can
be easily modified to suit a broad range of applications, and demonstrates the
ease of using and interfacing the Linx modules.
