MAD1108

ULTRA LOW CAPACITANCE MULTI-LINE STEERING DIODE ARRAY

ISO 9001: 2015 CERTIFIED

DESCRIPTION

The MAD1108 is a low distoron steering diode. This device is intended for use in high frequency analog or digital

data I/O ports for protecon against Electrostac Discharge (ESD) and Electrical Fast Transients (EFT). The MAD1108 is

connected between rail-to-rail voltage bus or rail-to-ground for clamping and diverng overvoltage transients for the

protecon of sensive network interface circuits.

This device provides low capacitance, which insures signal integrity up to 900MHz, while complete isolaon between

adjacent diodes keeps cross-talk to a minimum. The MAD1108 is available in a 16 pin DIP and meets the IEC 61000-4-

2, IEC 61000-4-4 and IEC 61000-4-5 requirements.
