Test Conditions
V_SW3 (differential) = T_LINE to T_{TEST_OUT}
V_SW4 (differential) = R_LINE to R_{TEST_OUT}
V_SW7 (differential) = T_{TEST_OUT} to T_{TEST_IN}
V_SW8 (differential) = R_{TEST_OUT} to R_{TEST_IN}
Applied voltage maximum ±225 V to ground
All-Off state.
+25° C, V_SW (differential) = ±320 V
+85° C, V_SW (differential) = ±330 V
-40° C, V_SW (differential) = ±310 V

SW3 & SW4
SW7 & SW8
V_SW (on) = ± 10 V, +25° C
V_SW (on) = ± 10 V, +85° C
V_SW (on) = ± 10 V, -40° C
Test_OUT switches on, all other switches
off. Apply ±1 kV 10x1000 μs pulse with
appropriate protection in place.
+25° C, Logic inputs = gnd,
V_SW3 (T_{TEST_OUT}) = ±225 V
V_SW4 (R_{TEST_OUT}) = ±225 V
+85° C, Logic inputs = gnd,
V_SW3 (T_{TEST_OUT}) = ±225 V
V_SW4 (R_{TEST_OUT}) = ±225 V
-40° C, Logic inputs = gnd,
V_SW3 (T_{TEST_OUT}) = ±225 V
V_SW4 (R_{TEST_OUT}) = ±225 V
