Logic - Signal Switches, Multiplexers, Decoders is a type of integrated circuit. Among them, MC100E158FN is a type of CMOS device with Built-in pull resistors, enabling it to serve as a straightforward multiplexer. This article will discuss the application field and working principle of the MC100E158FN.The MC100E158FN is an 8-channel, low-power, monolithic CMOS Multiplexer with Built-in pull resistors. It integrates two control bits (CE and OE) for 10thordered source and/or drain type switching of data. The device has thirty-two pads (eight additional pads than the MC100E156FN) to cater the on-chip pull resistors.The device uses passive-pulled terminated edges of each input to reduce power consumption. The use of passive pull resistors in the Mux reduces the power consumption of the Mux to its lowest possible level. The MC100E158FN is designed to reduce the effect of non-ideal waveforms which is caused due to the non-ideal pull-up devices at switches.The total leakage current of the device is kept within acceptable limits. A feature of the MC100E158FN is that the device provides voltage and temperature compensation making it more tolerant of temperature changes.The MC100E158FN has a few specific application fields such as CMOS logic, address decoding, data routing, and waveform shaping. It can be used in mobile phone applications, cameras, and many other portable electronic devices.Examples of waveform shaping that the MC100E158FN is suitable for include pulse width modulation, pulse delay modulation, or pulse coding modulation (PCM). These techniques are used in various forms of communication systems, including analog and digital transmission systems.The working principle of the MC100E158FN can be divided into two parts: the selection circuit and the pull resistor. The selection circuit consists of the differential pairs of transistors that serve as the switching element. The differential pairs are connected in series to the digital control inputs. When the control input is high, one of the differential pairs is turned on while the other is turned off. This connection results in the selection of one of the outputs.The pull resistor, meanwhile, consists of two transistors connected in series to each other. The pull resistor is used to provide active current sourcing or sinking to the outputs. By using this technique, the output currents of the device can be kept low, allowing for the device to operate at low power levels.In conclusion, the MC100E158FN is a low-power CMOS multiplexer with built-in pull resistors. The device is designed to reduce non-ideal waveforms, as well as reduce power consumption. The multiplexer is capable of addressing data routing and waveform shaping applications. The working principle of the device consists of the selection circuit and the pull resistor, which allow for active current sourcing to the outputs.
