I/O Pins Configuration Table
Notes:
1. At IrDA mode, it 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
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 µs, 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
5. Regulated, 2.4V to 3.6V
6. Logic high turns on the RC LED. If held high longer than 50 µs, 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.

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
The Application Engineering
Group is available to assist
you with the application
design associated with HSDL-
3007 infrared transceiver
module. You can contact them
through your local sales
representatives for additional
