Notes:
1. CX1 must be placed within 0.7 cm of HSDL-3000 to obtain optimum noise immunity.
2. In environments with noisy power supplies, supply rejection can be enhanced by including

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 during handling and
assembly of this component to prevent damage and/or degradation, which may be induced by ESD.

Output is a low pulse response when a light pulse is seen.
Notes
Tied through external resistor, R1, to regulated V
off. TXD must be either driven high or low. Do NOT float the pin.
Complete shutdown TXD, RXD, and PIN diode.
Regulated, 2.7 to 5.5 volts.
Connect to system ground.
Connect to system ground via a low inductance trace. For best performance,
do not connect to GND directly at the part.
