description
The TISP61089A is a dual forward-conducting
Terminals K1, K2 and A correspond to the alternative
buffered p-gate overvoltage protector. It is
line designators of T, R and G or A, B and C. The
negative protection voltage is controlled by the voltage,
designed to protect monolithic SLICs (Subscriber

applied to the G terminal.
Line Interface Circuits) against overvoltages on
the telephone line caused by lightning, a.c.
power contact and induction. The TISP61089A limits voltages that exceed the SLIC supply rail voltage. The
TISP61089A parameters are specified to allow equipment compliance with Bellcore GR-1089-CORE,
Issue 1.
The SLIC line driver section is typically powered from 0 V (ground) and a negative voltage in the region of
-10 V to -100 V. The protector gate is connected to this negative supply. This references the protection
(clipping) voltage to the negative supply voltage. As the protection voltage will then track the negative supply
voltage the overvoltage stress on the SLIC is minimised.
