SOT23
PDIP
IP 1-3
These are the switch inputs which when operated wake up the RF803E and cause transmission.
They may be switched directly to Ground. Transmission occurs for the duration of the switch
operation.
Vcc
The power supply needs to be a stable regulated voltage between 2.5 and 5.5V with <10mV ripple.
Note that in idle mode the transmitter current drain is typically only 100nA.
GND
Ground connection
TX
Data Output, this is a standard CMOS / TTL output that may be connected directly to the data input
pin of the RF Module. In the event that this represents a load to Vcc then a buffer stage between
the data output and the RF module will be required.
