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.
