5 ? 2007 semtech corp. www.semtech.com protection products rclamp0504p device connection options for protection of four high-speed data lines this device is designed to protect data lines by clamping them to a fixed reference. when the voltage on the protected line exceeds the reference voltage 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 center pin should be connected directly to a ground plane. the path length is kept as short as possible to minimize parasitic inductance. pin 2 is not connected. the positive reference is connected at pin 5. the options for connecting the positive reference are as follows: 1. to protect data lines and the power line, connect pin 5 directly to the positive supply rail (v cc ). in this configuration the data lines are referenced to the supply voltage. the internal tvs diode prevents over-voltage on the supply rail. 2. in applications where the supply rail does not exit the system, the internal tvs may be used as the reference. in this case, pin 5 is not connected. the steering diodes will begin to conduct when the voltage on the protected line exceeds the working voltage of the tvs (plus one diode drop). protection of four data lines and power supply line applications information protection of four data lines using internal tvs diode as reference 1 gnd 1 gnd figure 1 figure 1 figure 1 figure 1 figure 1 . pin conf . pin conf . pin conf . pin conf . pin conf iguration (t iguration (t iguration (t iguration (t iguration (t op side vie op side vie op side vie op side vie op side vie w) w) w) w) w) n i pn o i t a c i f i t n e d i 6 , 4 , 3 , 1s e n i l t u p t u o / t u p n i 2d e t c e n n o c t o n 5c / n r o ) l a n o i t p o ( v 5 b a t r e t n e cd n u o r g 1 gnd 2 3 6 5 4
