LEDA LED Driver Anode
(Power)
This output is connected to the LED anode. Current to the LED is sourced through
an external resistor.
TXD Transmit Data
(Input, active high)
This CMOS input is used to transmit serial data. This input has an internal pull-
down resistor that is disabled (open-circuited) during shutdown.
RXD/Receive Data
(Output, active low)
This output indicates received serial data. It is a tri-state, slew rate controlled
CMOS output (tri-stated during shutdown) driver capable of driving a standard
CMOS load. No external resistor is required.
SD Shutdown
(Input, active high)
This input is used to place the integrated circuit into shutdown mode. Module shut-
down current is influenced by the choice of capacitor used from VCC to ground.
VCC Positive Supply
(Power)
Connect to positive power supply (2.4–5.5 V). Filter with a 0.33-µF ceramic
bypass capacitor and terminating resistor as close as possible to the VCC pin.
GND Ground
(Power)
Connect to ground of the power supply. A solid ground plane is recommended for
proper operation.
TAB
(Shield)
The Shield tab must be soldered to the ground plane.
