Triple 2-Channel Analog Multiplexer/Demultiplexer
The CD4053 is a high-performance, low-power, triple 2-channel analog multiplexer/demultiplexer IC, suitable for various applications:
Key Features:
Triple 2-channel: Three independent 2-channel multiplexers.
Analog multiplexer (MUX): 2-to-1 or 1-to-2 configuration.
Analog demultiplexer (DEMUX): 1-to-2 configuration.
High-speed operation: Propagation delay: 10-30 ns.
Low power consumption: Maximum 80 μA.
Wide operating range: 4.5V to 15.5V.
