Description
The DALC208SC6Y diode array is designed to
protect components which are connected to data
and transmission lines from overvoltages 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 DALC208SC6Y
prevents significant signal distortion.
