Product Description
The USB is a four wire system utilizing a two wire twisted pair for transferring data, and two lines to supply power and ground
connection to hubs and devices. The USB allows for two modes of signaling. The low speed mode is defined at 1.5Mbs with
the full speed at 12Mbs.
The PACUSB100 provides ESD protection with EMI filtering and termination. It is ideal for protecting vulnerable components
in devices like keyboard, mouse, scanner/printer, etc. The PACUSB100 also supports upstream ports. California Micro Devices
also offers a complementary device (PACUSB200) to provide filtering and ESD protection for downstream ports. The PACUSB100
has the following characteristics:
