DESCRIPTION

NC − No internal connection

†

When read horizontally, Pin 1 is the bottom left pin.

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) 1.1 ports. Note

that the input capacitance of the device makes it

unsuitable for high-speed USB 2.0 applications.

(TOP VIEW)

GND

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.

GND

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.

CURRENT vs VOLTAGE

7.5

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.
