(1) lower the inductance of the wiring by making lines wider and shorter. (2) insert capacitors with good frequency characteristics close to the ic. (3) consider adopting the following methods if the cpu and this ic are mounted on different printed circuit boards that could easily have different ground potentials. ? connect s-gnd to the cpu ground and connect p-gnd to the power system ground. ? insert resistors of about 10k in series between the controller outputs and the inputs on this ic. this catalog provides information as of june, 2011. specifications and information herein are subject to change without notice.
