New USB Micromodule Transceiver Protects Against High Voltages

Linear Technology Corp. recently introduced the LTM2894 USB µModule (micromodule) reinforced isolator that guards against ground-to-ground voltage differentials and large common-mode transients. With a rugged interface and internal isolation, the LTM2894 is well suited for implementing USB in harsh environments where protection from high voltages is needed.LTM2894
