The following handling practices pract are recommended. 1 Devices should be handled on benches with conductive and grounding surfaces. 2 All personnel, test equipment and tools shall be grounded. 3 Do not handle the devices by their leads. 4 Store devices in protective foam or carriers. 5 Avoid the use of non-conductive plastics, rubber, or silk in the area where the devices are handled 6 All modules shall be packaged in materials that are anti anti-static static to protect against adverse electrical environments. Avoid applications of any voltage higher than maximum rated voltages to this part. For proper operation, any VIN or VOUT should sho be 7 constrained to the range GND ≤ (VIN or VOUT) ≤ VCC. Unused inputs must always be tied to an appropriate logic voltage (e.g. (e.g either GND or VCC). Unused outputs must be left open. DS-5896 Rev 01 ITR-D3T-SD6-4 Warnings Handling Precautions: This device is susceptible to damage as a result of electrostatic discharge (ESD). A static free environment is highly recommended. Follow guidelines according to proper ESD procedures. Laser Safety: Radiation emitted by laser devices can be dangerous to human eyes. Avoid eye exposure to direct or indirect radiation.
