The HEF4053B is a triple single-pole double-throw (SPDT) analog switch, suitable for use
as an analog or digital multiplexer/demultiplexer. Each switch has a digital select input
(Sn), two independent inputs/outputs (nY0 and nY1) and a common input/output (nZ). All
three switches share an enable input (E). A HIGH on E causes all switches into the
high-impedance OFF-state, independent of Sn.
VDD and VSS are the supply voltage connections for the digital control inputs (Sn and E).
The VDD to VSS range is 3 V to 15 V. The analog inputs/outputs (nY0, nY1 and nZ) can
swing between VDD as a positive limit and VEE as a negative limit. VDD VEE may not
exceed 15 V. Unused inputs must be connected to VDD, VSS, or another input. For
operation as a digital multiplexer/demultiplexer, VEE is connected to VSS (typically
ground). VEE and VSS are the supply voltage connections for the switches.
