ALPHA Encoder / Decoder IC’s
Receiver Decoder RF803D-ALPHA
RF803-ALPHA
Functional Description
The RF803D-ALPHA is simple to use. As shown in the typical application circuit below, the
RF803D-ALPHA has the capability to learn up to 30 unique RF803E-ALPHA transmitters.
The digital outputs may be configured as latching or momentary action.
Latch
= the output will change state on each successive transmit of the encoder.
Momentary
= the output will only operate for as long as the RF803E-ALPHA encoder is
transmitting.
The RF803D-ALPHA can be configured to work with an ALPHA TRX or TX by setting the
TX/TRX pin.
