TISP61512P Overview
The TISP61511D and TISP61512P are dual forward-conducting buffered p-gate overvoltage protectors. They are designed to protect monolithic Subscriber Line Interface Circuits, SLICs, against overvoltages on the telephone line caused by lightning, ac power contact and induction. The TISP61511D and TISP61512P limit voltages that exceed the SLIC supply rail voltage.
