I/O 1 I/O 2 I/O 3 I/O 4 6 5 4 1 2 3 In applications lacking a positive supply reference an external TVS diode may be used as a reference. For these applications, the TVS is connected between pin 2 and the ground plane. The steering diodes will conduct whenever the voltage on the protected line exceeds their forward voltage plus the working voltage of the TVS diode (Vc=Vf + VTVS). In this case, the effective capacitance of the steering diodes will be higher than if a bias was applied. D1 D2 D3 D4 D5 D6 D7 D8 5 NUP4304MR6 Equivalent Circuit 2 134 6 |
