description
The SN65220 is a single transient voltage
suppressor and the SN75240 and SN65240 are
dual transient voltage suppressors designed to
provide additional electrical noise transient
protection to two USB ports. Any cabled I/O can
be subjected to electrical noise transients from
various sources. These noise transients can
cause damage to the USB transceiver and/or the
USB ASIC if they are of sufficient magnitude and
duration. The USB ports are typically implemented in 3-V or 5-V digital CMOS with very limited
ESD protection. The SN65220, SN75240, and
SN65240 can significantly increase the port ESD
protection level and reduce the risk of damage to
the large and expensive circuits of the USB port.
The SN75240 is characterized for operation from
0°C to 70°C. The SN65220 and SN65240 are
characterized for operation from –40°C to 85°C.
IEC1000-4-2 ESD performance is measured at
the system level and system design influences the
results of these tests. A high compliance level may
be attained with proper system design.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
