LCAS Asymmetrical Multiport Device

This is an integrated multichip asymmetrical solution for protecting multiple twisted pair
from overvoltage conditions. Based on a six-pin surface mount SOIC package, it is

T2 equivalent to four discrete DO-214AA or two TO-220 packages. Available in surge
5 current ratings up to 500 A, the multiport line protector is ideal for densely populated

G2 line cards that cannot afford PCB inefficiencies or the use of series power resistors.
4 For a diagram of an LCAS Line Circuit Access Switch application, see the following
