Notes:
1. Internally connected to RC LED driver. Leave this pin unconnected.
2. Tied through external resistor, R3, to RC Vled. Refer to the table below for recommended series resistor value.
3. Tied through external resistor, R2, to IR Vled. Refer to the table below for recommended series resistor value.
4. Connect to ASIC logic controller supply voltage or V
5. This pin is used to transmit serial data when SD pin is low. If held high for longer than 50 µs, the LED is turned off. Do NOT float this pin.
6. This pin is capable of driving a standard CMOS or TTL load. No external pull-up or pull-down resistor is required. The pin is in tri-state when
7. Complete shutdown of IC and PIN diode. The pin is used for setting receiver bandwidth and RC drive programming mode. Refer to section on
8. Regulated, 2.4 V to 3.6 V.
9. Logic high turns on the RC LED. If held high longer than 50 µs, the RC LED is turned off. Do NOT float this pin.
10. Connect to system ground.
11, Connect to system ground via a low inductance trace. For best performance, do not connect directly to the transceiver GND pin.

the transceiver is in shutdown mode.
“Bandwidth Selection Timing” and “Remote Control Drive Modes” for more information. Do NOT float this pin.
CAUTIONS: The BiCMOS inherent to the design of this component increases the component’s susceptibility
to damage from electrostatic discharge (ESD). It is advised that normal static precautions be taken in handling
and assembly of this component to prevent damage and/or degradation which may be induced by ESD.
