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. *RoHS Directive 2002/95/EC Jan 27 2003 including Annex APRIL 2001 REVISED FEBRUARY 2005 Specifications are subject to change without notice.
