The HSDL-3007 can be shutdown completely to achieve very low power consumption. In the shutdown mode, the PIN diode will be inactive and thus producing very little photocurrent even under very bright ambient light. It is also designed to interface to input/ output logic circuits as low as 1.8V. These features are ideal for battery operated mobile devices such as PDAs and mobile phones that require low power consumption Application Support Information

Notes: 1. At IrDA mode, is a contant current source. At RC mode, the current can be controlled by external resistor, R1, which is tied to Vled. Refer to the table below for recommended series resistor value. 2. Complete shutdown of IC and PIN diode. Do NOT float this pin. 3. This pin is used to transmit serial data when SD pin is low. If held high for longer than 50 ”s, the LED is turned off. Do NOT float this pin. 4. 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 transceiver is in shutdown mode. 5. Regulated, 3.6V 6. Logic high turns on the RC LED. If held high longer than 50 ”s, the RC LED is turned off. Do NOT float the pin. 7. Connect to ASIC logic controller supply voltage or Vcc. The voltage at this pin should be equal to or less than Vcc. 8. Connect to system ground.
CAUTION: 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
