description
The 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 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 to 70°C. The SN65220 and SN65240 are characterized for operation from 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.
