Typical Applications
The MS deccoder is ideal for replicating button presses for remote control
applications. An example application circuit is shown in the figure below.
SPDT switches are used to select the baud rate and set the latch mode so
that pull-down resistors are not needed.
The RX_CNTL line can be connected to the PDN line of the receiver or it
can be connected directly to ground.
TX_ID can be connected to a microprocessor or a PC to record the
transmitter identity. Application Note AN-00156 has sample code that will
read the transmitter ID and display the ID number on a LCD screen.
A LED indicator is attached to the MODE_IND line to provide visual
feedback to the user that an operation is taking place. This line will
source a maximum of 25mA, so the limiting resistor may not be needed,
depending on the LED chosen and the brightness desired.
The LEARN line is connected to a button that will pull the line high when
pressed. Since the line does not have an internal pull-down resistor, a
100k
Ω resistor is used to pull the line to ground when not in use.
The DATA_IN line is connected directly to the data output of the receiver.
