Larger Multiplexers can be constructed by using smaller multiplexers by chaining them together. For example, an 8-to-1 multiplexer can be made with two 4-to-1 and one 2-to-1 multiplexers. Combinational circuits&colon; arithmetic circuits, code converters, multiplexers and decoders. Multiplexers, decoders, state machines, and other sophisticated digital devices may use inverters. Beginning with the Mostek 4096 DRAM, address multiplexing implemented with multiplexers became common. Transmission gates are used in order to implement electronic switches and analog multiplexers. Transmission gates may be used as analog multiplexers instead of signal relays. Prime applications are optical protection, test systems, remotely reconfigurable add-drop multiplexers, and sensing. The clock and data distribution product line offers buffers, logic translators and multiplexers. The 7400 series offered data-selectors, multiplexers, three-state buffers, memories, etc. MFTs can include multiplexers and demultiplexers, codecs or DSP effects like reverb. Devices called "Input/Output Multiplexers (IOMs)" served as intelligent I/O controllers for communication with most peripherals. It is common to use this logic family for multiplexers and latches. The SRB RGA rates passed through the orbiter flight aft multiplexers/demultiplexers to the orbiter GPCs. Add-drop multiplexers (ADMs) are the most common type of network elements.
