Description

This is Triple 2-channel analogue multiplexer/demultiplexer. HEF4053B Triple single-pole double-throw analog switch Rev. 11 11 September 2014 Product data sheet 1. General description 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 co.
