Surge Protection
The SLIC device, in conjunction with an external protection
bridge, will withstand high voltage lightning surges and
power line crosses.
The voltage withstand capability of pins ‘Tip’, ‘Ring’ and
‘RFs’ is ±450V with respect to ground, as shown in Table 1.

V_RMS
This device is intended for use with an appropriate
secondary protection circuit scheme.
The SLIC will withstand longitudinal currents up to a
maximum or 30mA_RMS, 15mA_RMS per leg, without any
performance degradation.
