DESCRIPTION
The KH Series is ideally suited for volume use
in OEM applications such as remote control /
command and keyless entry. It combines an RF
receiver with an on-board decoder. When
paired with a matching KH Series transmitter /
encoder module, a highly reliable wireless link
is formed, capable of transferring the status of 8
parallel inputs over distances in excess of 300
feet. Ten tri-state address lines provide 59,049
(3
uniqueness. Housed in a compact SMD
package, the KH module utilizes a highly
optimized SAW architecture to achieve an
unmatched
efficiency,
components, are required (except an antenna),
making design integration straightforward.

... D7 A0 GND RXD-XXX-KH Figure 12: Basic Remote Control Receiver The ten-position DIP switch is used to set the address to either ground or floating. Since the floating state is a valid state, no pull-up resistors are needed. The data line outputs can only source about 1mA of current, so transistor buffers are used to drive the buzzer and LED. 1mA is sufficient to activate most microcontrollers, but the manufacturer’ ...
