Product overview
74HC4053 Triple 2-Channel Analog Multiplexer / Demultiplexer IC
The 74HC4053 is a high-speed CMOS triple 2-channel analog multiplexer/demultiplexer. Internally, it contains three independent SPDT (single-pole double-throw) analog switches, allowing analog or digital signals to be selected and routed under digital control.
Each switch section has its own digital select input, two independent input/output terminals and one common input/output terminal. A shared Enable/Inhibit input can disconnect all three switches simultaneously.

Three Independent Analog Switches
The 74HC4053 contains three independently controlled 2:1 switches. Each section can select between two signal paths, making the device useful for signal routing, channel selection and multiplexing applications.
Analog and Digital Signal Switching
The bidirectional switch structure allows the HC4053 to handle both analog and digital signals. Depending on the supply arrangement, it can also accommodate bipolar analog signals, making it useful in audio, instrumentation and signal-conditioning circuits.
Common Enable / Inhibit Control
A common enable input controls all three switch sections. When the inhibit/enable input is asserted to the OFF state, all switches are disconnected regardless of the individual channel-selection inputs.
