The EClampTM3343C protection and termination device works with both upstream and downstream USB 2.0 and on-the-go (OTG) ports in portable electronics and peripherals. It protects USB ports from electrostatic discharge (ESD), filters electromagnetic interference (EMI), and incorporates terminating 1.5-k(omega) pull-up and pull-down resistors that enable it to identify the type of port it is supporting. It also integrates a 33-(omega) series termination resistor for impedance matching. Pricing is $0.40 each in 10,000-piece lots. Lead-free versions are the same price.
