Device Connection Options for Protection of Two
High-Speed Data Lines
This device is designed to protect two data lines from
transient over-voltages by clamping them to a fixed
reference. When the voltage on the protected line
exceeds the reference voltage (plus diode V
steering diodes are forward biased, conducting the
transient current away from the sensitive circuitry.
Data line inputs are connected at pins 1 and 5. The
outputs are connected at pins 10 and 6 respectively.
The negative reference is connected at pins 2, 3, and
4. These pins 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 is connected at
pins 7, 8, and 9. The options for connecting the
positive reference are as follows:
1. To protect data lines and the power line, connect
2. In applications where no positive supply reference
