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 implement-

ed 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.
