7 / 12 page Pin Name Function 1F GND Fault ground 2T BAT Connect to TIP on SLIC side 3T LINE Connect to TIP on line side 4T RING Connect to return ground for ringing generator 5T ACCESS Test access 6V DD +5V supply 7 TSD Temperature shutdown pin. Can be used as a logic level input or output. See Tables 6, 7 and 9 for more details. As an output, will read +5V when device is in its operational mode and 0V in the thermal shutdown mode. To disable the thermal shutdown mechanism, tie this pin to +5V (NOT Recommended). 8D GND Digital ground 9IN ACCESS Logic level switch control 10 IN RING Logic level input switch control 11 LATCH Data latch control, active high, transparent low 12 R ACCESS Test access 13 R RING Connect to ringing generator 14 R LINE Connect to RING on line side 15 R BAT Connect to RING on SLIC side 16 V BAT Battery voltage. Used as a reference for protection circuit Table 9.
