I/O Pins Configuration Table
Notes:
1. This pin can be connected directly to V
2. Internally connected to the LED driver.
3. This pin is used to transmit serial data when SD pin is low. Do not float the pin.
4. This pin is capable of driving a standard CMOS or TTL load. No external pull-up or pull down resistor is required. It is in tri-state
5. The transceiver is in shutdown mode if this pin is high. Do not float the pin.
6. Regulated, 2.7 to 3.6 volts.
7. Connect to system ground.
Recommended Application Circuit Components
Notes:
8. CX1 must be placed within 0.7 cm of the HSDL-3208 to obtain optimum noise immunity.
9. In environments with noisy power supplies, supply rejection performance can be enhanced
