description
The TISP61089 is a dual forward-conducting buffered p-gate overvoltage protector. It is designed to protect monolithic SLICs (Subscriber Line Interface Circuits) against overvoltages on the telephone line caused by lightning, a.c. power contact and induction. The TISP61089 limits voltages that exceed the SLIC supply rail voltage. The TISP61089 parameters are specified to allow equipment compliance with Bellcore GR-1089-CORE, Issue 1.
