HEF4052BTT

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.

V_DD and V_SS are the supply voltage connections for the digital control inputs (S1 and S2, and E). The V_DD to V_SS range is 3 V to 15 V. The analog inputs/outputs (nY0 to nY3, and nZ) can swing between V_DD as a positive limit and V_EE as a negative limit. V_DD- V_EE may not exceed 15 V. Unused inputs must be connected to V_DD, V_SS, or another input. For operation as a digital multiplexer/demultiplexer, V_EE is connected to V_SS (typically ground). V_EE and V_SS are the supply voltage connections for the switches.
