Description
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.
