DESCRIPTION
The SN65220 is a single transient voltage suppressor and
the SN65240 and SN75240 are dual transient voltage
suppressors designed to provide electrical noise transient
protection to Universal Serial Bus (USB) fullspeed ports.
Note that the input capacitance of the device makes it
unsuitable for high-speed USB 2.0 applications.
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.
USB ports are typically implemented in 3-V or 5-V digital
CMOS with very limited ESD protection. The SN65220,
SN65240, and SN75240 can significantly increase the
port ESD protection level and reduce the risk of damage
to the circuits of the USB port.
The IEC1000-4-2 ESD performance of the SN65220,
SN65240, and SN75240 is measured at the system level.
Therefore, system design impacts the results of these
tests. A high compliance level may be attained with proper
board design and layout.
APPLICATIONS
D USB FullSpeed Host, Hub, or Peripheral
Ports
