pb1507gv note 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. 10 000 pf) to the v cc pin. recommended soldering conditions this product should be soldered in the following re commended conditions. other soldering methods and conditions than the recommended conditions are to be consulted with our sales representatives. pb1507gv soldering method soldering condi tions recommended condition symbol infrared ray reflow package peak temperature: 235 c, hour: within 30 s.
