Applications Information
Device Connection Options for Protection of Eight
High-Speed Data Lines
This device is designed to protect eight 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 F ) the
steering diodes are forward biased, conducting the

transient current away from the sensitive circuitry.
Data lines are connected at pins 1, 2, 4, 5, 7, 8, 9,
and 10. The negative reference is connected at pin 6.
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 is connected at pin 3. The
options for connecting the positive reference are as
follows:

Pin Configuration
1. To protect data lines and the power line, connect
pin 3 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 3 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).
Universal Serial Bus ESD Protection
The RClamp0508M may be used to protect USB 2.0
ports on monitors, computers, peripherals or portable
systems. Each device will protect up to four USB ports.
When the voltage on the data lines exceed the bus
voltage (plus one diode drop), the internal rectifiers are
forward biased conducting the transient current away
from the protected controller chip. The TVS diode
directs the surge to ground. The TVS diode also acts
to suppress ESD strikes directly on the voltage bus.
Thus, both power and data pins are protected with a
single device.
