Subscriber loop connection RING (Channel A)
Subscriber loop connection RING (Channel B)
Subscriber loop connection TIP
Auxiliary positive battery supply voltage used in ringing mode
(5 V
Positive supply voltage (+3.3 or +5 V), referred to AGND
Second negative battery supply voltage (–15 V
Most negative battery supply voltage; chip substrate potential
(–20 V
except TIP and RING
Common mode line potential with high output resistance (160 k );
an external capacitance allows supply voltage filtering
ACP - ACN: differential two-wire AC input voltage; at TIP/RING
amplified by -6
DCP - DCN: differential DC or ring input voltage; at TIP/RING amplified
by -30 (ACTL, ACTH) and -60 (ACTR mode), respectively
Ternary logic input, controlling the operation mode
Ternary logic input, controlling the operation mode
in case of thermal overload (chip temperature exceeding 165 °C) this
pin sinks a current of typically 150 A.
Current output: longitudinal line current scaled down by a factor of 100
Current output: transversal line current scaled down by a factor of 50
Not connected
