CD4053 belongs to the CD4000 IC series. The CD4053 is an analog multiplexers/demultiplexers are digitally controlled analog switches having low “ON” impedance and very low “OFF” leakage currents. Control of analog signals up to 15Vp-p can be achieved by digital signal amplitudes of 3−15V. The IC is always available in a 16-pin hermetically sealed dual in line package. CD4053 offers various features such as low thermal dissipation and high noise immunity.
Multiplexer
A multiplexer is a combinational logic circuit that switches one of several input lines to a single common output line. The select lines determine which input is connected to the output, and also to increase the amount of data that can be sent over a network within a certain time. It is also called a data selector.
Demultiplexer
A decoder/demultiplexer is a combinational logic circuit & an integral part of todays consumer scale electronics. It is designed to switch one common input line to one of several separate output lines. So, A demultiplexer converts a serial data signal at the input to a parallel data at its output lines.
CD4053 Key Features
- Wide range of digital and analog signal levels: digital 3 – 15V, analog to 15Vp-p
- Low “ON” resistance: 80Ω (typ.) over entire 15Vp-p
- signal-input range for VDD − VEE = 15V
- High “OFF” resistance:
- channel leakage of ±10 pA (typ.) at VDD − VEE = 10V
- Logic level conversion for digital addressing signals of
- 3 – 15V (VDD − VSS = 3 – 15V) to switch analog signals
- to 15 Vp-p (VDD − VEE = 15V)
- Binary address decoding on chip
