Logic - Signal Switches, Multiplexers, Decoders

The MC100E171FN is a high-speed CMOS ECL-to-TTL logic signal switch and multiplexer/demultiplexer. It is used to switch between two different logic signals, multiplex multiple inputs into one output, and demultiplex one input into multiple outputs. This device provides an efficient and cost-effective solution for switching and multiplexing/demultiplexing applications.

Application Field

The MC100E171FN is a high-speed CMOS logic signal switch and multiplexer/demultiplexer. It is suitable for many applications, including switching between logic levels, multiplexing one or more input signals into one output, or demultiplexing one input into several outputs. It is also useful for extending the range of a logic signal, converting between voltage levels, and for signal buffering and isolation.Moreover, this device is used in communications systems, signal routing and timing applications, advanced logic gate designs, system interface, logic signal conversion, and bootstrapping displays.

Working Principle

The MC100E171FN utilizes two operating states: an active low state and an inactive low state. When in the active state, the output will be in the low voltage level, while in the inactive state, the output will be in the high voltage level. The signal switch and multiplexer/demultiplexer can be controlled by two internal signals: EN (enable) and SEL (select). The EN signal is used to control the device. When it is low, the device is enabled and will allow the switching between logic levels. The SEL signal is used to select the logic levels when multiple inputs are connected. Furthermore, the SEL signal also can be used as an address input when multiplexing/demultiplexing is enabled. When in the active state, the device can switch between two different levels. The switching speed of the device depends on an external clock pulse. This pulse will determine the switching frequency among the two different logic levels. The multiplexer/demultiplexer feature of the device allows one input to be routed to multiple outputs, while one output can be selected from multiple inputs. The input is multiplexed/demultiplexed based on the SEL signal, which is also used as an address input.In summary, the MC100E171FN is a high-speed CMOS ECL-to-TTL logic signal switch and multiplexer/demultiplexer. It is suitable for many applications, including switching between logic levels, multiplexing/demultiplexing one or more input signals into one output, extending the range of a logic signal, converting between voltage levels, and for signal buffering and isolation. The device is controlled by the EN and SEL signals, which are used to control the switching between different levels and to select the logic levels when multiple inputs are connected.
