Description
Array of 8 or 12 diodes configured by cells of 2
diodes, each cell being used to protect signal line
from transient overvoltages by clamping action.
As maximum voltage of each diode is 18 V,
maximum input voltage range between two I/Os is
either 0 V to 18 V (REF1 = 0 V and REF2 =
+18 V) or -9 V to +9 V (REF1 = -9 V and REF2 =
+9 V)

Array of 8 or 12 diodes
Low input capacitance
Suitable for digital line protection
IEC 61000-4-2 Level 4
– 15kV (air discharge)
– 8kV (contact discharge)
Protection of logic side of ISDN S-interface
Protection of I/O lines of microcontroller
