January 2008 Rev 6 1/8 DA108S1 DA112S1 Diode array Features ■ Array of 8 or 12 diodes ■ Low input capacitance ■ Suitable for digital line protection Complies with following standards: ■ IEC 61000-4-2 Level 4 – 15kV (air discharge) – 8kV (contact discharge) Applications ■ Protection of logic side of ISDN S-interface ■ Protection of I/O lines of microcontroller ■ Signal conditioning 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) Figure 1.
