MAD1108
ultRA low cAPAcitAnce Multi-line steeRing DioDe ARRAy
DescRiPtion
The MAD1108 is a low distortion steering diode. This device is intended for use in high frequency analog or digital
data I/O ports for protection against Electrostatic Discharge (ESD) and Electrical Fast Transients (EFT). The MAD1108 is
connected between rail-to-rail voltage bus or rail-to-ground for clamping and diverting overvoltage transients for the
protection of sensitive network interface circuits.
This device provides low capacitance, which insures signal integrity up to 900MHz, while complete isolation 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.
