Notes:
1. Tied through external resistor, R2, to Vled. Refer to the table below for recommended series resistor value.
2. This pin is used to transmit serial data when SD pin is low. If held high for longer than 50 ms, the LED is turned off. Do NOT float this pin.
3. 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 the
4. Complete shutdown of IC and PIN diode. The pin is used for setting IR receiver bandwidth, range of IR LED current and RC drive programming
5. Connect to ASIC logic controller supply voltage or Vcc. The voltage at this pin should be equal to or less than Vcc.
6. Logic high turns on the RC LED. If held high longer than 50 ms, the RC LED is turned off. Do NOT float the pin.
7. (i) Regulated, 2.4V to 3.6V
8. Connect to system ground.
