DALC208SC6
LOW CAPACITANCE
DIODE ARRAY
MAIN APPLICATIONS
Where ESD and/or over and undershoot protection
for datalines is required :
Sensitive logic input protection
Microprocessor based equipment
Audio / Video inputs
Portable electronics
Networks
ISDN equipment
USB interface
DESCRIPTION
The DALC208SC6 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 DALC208SC6
prevents from significant signal distortion.
