CD4052 CD4052BE 4-Channel Analog Multiplexer IC

The CD4052 is an analog multiplexer/demultiplexer IC from the CD4000 series. It’s a dual 4-channel analog switch, meaning it can handle two separate 4:1 multiplexers or demultiplexers, depending on how it’s used.

Key Features of CD4052:

• Dual 4-Channel MUX/DEMUX: Two independent 4-channel analog switches.

• Analog or Digital Signals: Can switch analog signals (e.g. audio) or digital logic signals.

• Bidirectional: Can pass signals in both directions.

• Low “On” Resistance: Typically around 125Ω at 15V.

• Wide Voltage Range: Operates from 3V to 20V supply voltage.

• Control via Logic Inputs:

  • A, B (Address Inputs): Select one of the four channels.

  • INHIBIT (Enable/Disable): Disables all switches when high.

• Common I/O pins:

  • X (for first 4:1 MUX)

  • Y (for second 4:1 MUX)
