Function : Triple single-pole double-throw analog switch
Maker : NXP Semiconductors.
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 Ecauses all switches into the high-impedance OFF-state, independent of Sn.
