he SRV05-4 is designed to protect four data lines from transient over-voltages by clamping them to fixed refer- ence. When the voltage on the protected line exceeds the reference voltage (plus diode VF) the steering diodes are forward biased, conducting the transient current away from the sensitive circuitry. Data lines are connected at pins 1, 3, 4 and 6. The negative reference (REF1) is connected at pin 2. This pin should be connected directly to a ground plane on the board for best results. The path length is kept as short as possible to minimize parasitic inductance. The positive reference (REF2) is connected at pin 5. 123 654 I/O 1 I/O 2 I/O 3 I/O 4 To Protected IC To Protected IC VCCSRV0 5-4 on Video Interface Application 1 2 3 6 5 4 1 2 3 6 5 4 VCC VCC SRV05-4 4-Line Low Capacitance TVS Diode ArrayVer1.51 - 4 - www.wpmtek.com
