The document is a data sheet for the MC14051B, MC14052B, and MC14053B analog multiplexers/demultiplexers, which are digitally-controlled analog switches.
These devices feature low ON-impedance and very low OFF leakage current, and can control analog signals up to the complete supply voltage range.
They also have triple diode protection on control inputs, linearized transfer characteristics, and low noise.
The document includes maximum ratings, ordering information, marking diagrams, pin assignments, and detailed specifications for each device.
It also contains information on the company's Pb-Free strategy and soldering details.
