Notes
1.
With pin 19 = HIGH, then pins 7, 8, 15, 16 and 17 are address inputs.
With pin 19 = LOW, then pins 7, 8, 15, 16, and 17 are 4 or 5 address received outputs.
a) In Figs 5, 6 and 7 this HIGH/LOW switching is dependent on whether the transistor on pin 19 is fed via a series
resistor or not. In both applications pin 19, which toggles several times (see Fig.4) while a valid command is
acknowledged, can be used to activate (flash) an LED indicator.
A quartz crystal with a frequency of 4 MHz is recommended for the standard transmitter application.
Application as output requires connection of an external pull-up resistor.
