Please refer to Table 1 for VLED versus Series Resistor, R1.
No external pull-up or pull down resistor is required. It is in
If held high longer than ~ 50µs, the LED will be turned off.
Regulated, 2.4 to 3.6 Volts.
Function
Tied through external resistor, R1, to VLED from 2.4V to 4.5V.
This pin is capable of driving a standard CMOS or TTL load.
This pin is used to transmit serial data when SD pin is low.
The transceiver is in shutdown mode if this pin is high
Connect to ASIC logic controller Vcc Voltage as low as 1.5V.
Connect to system ground.
