The devices are capable of encoding 24 bits of information and then serially transmitting the data on their output pin.
A signal transmission is automatically activated when any of the data input lines change from high to low.
The device generates a signal on its output pin which is composed of a pilot signal, address codes, data codes and an end code.
This can be sent to RF transmitter circuits for wireless transmission.
Various configurations of address and data bits can be chosen according to which device is selected.
As all functions are integrated into the device, the simple addition of switches and RF module is that is required to implement a full RF encoder function.
All devices are supplied in 8-pin SOP packages.
Selection Table The devices encodes 24-bits of information however the address/data combination is selected according to which part number is selected.
