CD4052 Dual 4 Channel Analog Multiplexer or Demultiplexer IC

The IC CD4052 designed as a CMOS based high voltage Multiplexer and Demultiplexer IC. The IC widely used in circuit where a 4:1 MUX or a 1:4 DEMUX required in a Programmable Logic circuit Design. These IC capable of handling handle both analog and digital voltages. Hence used in Analog to Digital and Digital to Analog converters.

The analogue multiplexers and demultiplexers in the CD4052 series are digitally controlled analogue switches. They have a low “ON” impedance and very low leakage currents “OFF.” Furthermore, analogue signals up to 15Vp-p can be controlled using digital signal amplitudes of 315V. A differential 4-channel multiplexer, the CD4052BC has two binary control inputs, A and B, as well as an inhibit input. The differential analogue inputs are connected to the differential outputs by the two binary input signals, which select one of four pairs of channels to be turned on. Over the entire VDDVSS and VDDVEE supply voltage ranges, the MUX/DEMUX circuits dissipate very little quiescent power. Which is independent of the control signals’ logic state. Meanwhile, the IC’s output is always TTL, making it simple to interface with other TTL devices and microcontrollers. Thermal overload protection and ESD protection are among the many features included in the IC.

A multiplexer is a logic circuit that connects one or more input lines to a single common output line. The select lines decide which inputs are connected to which outputs, as well as how much data may be transferred over a network in a given amount of time. A combinational logic device that switches one common input line to one of several independent output lines is known as a decoder/demultiplexer. So, A demultiplexer is a device that converts a serial data signal to parallel data on its output lines.
