pb1509gv note on correct use (1) observe precautions for handling because of electro-static sensitive devices. (2) form a ground pattern as wide as possible to minimize ground impedance (to prevent undesired operation). (3) keep the wiring length of the ground pins as short as possible. (4) connect a bypass capacitor (e.g. 1000 pf) to the v cc pin. recommended soldering conditions this product should be soldered in the following recommended conditions. other solderi ng methods and conditions than the recommended conditions are to be consul ted with our sales representatives. pb1509gv recommended soldering method soldering conditions condition symbol infrared ray reflow package peak temperature: 235 c, hour: within 30 s.
