Description
The TISP61521 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 TISP61521 limits
voltages that exceed the SLIC supply rail voltage. The TISP61521 parameters are specified to allow equipment compliance with Bellcore
GR-1089-CORE, Issue 1 and ITU-T recommendation K.20.
