STMicroelectronics DALC208SC6
The DALC208SC6 diode array is designed to protect components which are connected to data and transmission lines from over voltages caused by electrostatic discharge (ESD) or other transients. It is a rail-to-rail protection device also suited for overshoot and undershoot suppression on sensitive logic inputs. The low capacitance of the DALC208SC6 prevents significant signal distortion.| Part No. | DALC208SC6 |
