HEF4053BT,652 and HEF4052BT,652 Dual/Triple analog switch IC chip SOIC16 package

HEF4053BT,652 and HEF4052BT,652 Dual/Triple analog switch IC chip SOIC16 package

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

The HEF4052B is a dual 4-channel analog multiplexer/demultiplexer with common channel select logic. Each multiplexer/demultiplexer has four independent inputs/outputs (nY0 to nY3) and a common input/output (nZ). The common channel select logic includes two select inputs (S1 and S2) and an active LOW enable input (E). Both multiplexers/demultiplexers contain four bidirectional analog switches, each with one side connected to an independent input/output (nY0 to nY3) and the other side connected to a common input/output (nZ). With E LOW, one of the four switches is selected (low-impedance ON-state) by S1 and S2. With E HIGH, all switches are in the high-impedance OFF-state, independent of S1 and S2. If break before make is needed, then it is necessary to use the enable input
