Telecom ICs

Tip-and-ring phone lines, VOIP, and PBX systems require efficient line monitoring and switching solutions. Littelfuse delivers. Our telecom ICs include N-channel depletion metal-oxide–semiconductor field effect transistors (MOSFETs), optically isolated multipurpose chips, and line card access switches. We also offer assemblies of solid state relays, optocouplers, bridge rectifiers, Darlington transistors, and Zenner diodes.
