The HEF4052B is a dual 4-channel analogue multiplexer/demultiplexer with common channel select logic. Each multiplexer/demultiplexer has four independent inputs/outputs (Y0 to Y3) and a common input/output (Z). The common channel select logic includes two address inputs (A0 and A1) and an active LOW enable input (E). Both multiplexers/demultiplexers contain four bidirectional analogue switches, each with one side connected to an independent input/output (Y0 to Y3) and the other side connected to a common input/output (Z). With E LOW, one of the four switches is selected (low impedance ON-state) by A0 and A1. With E HIGH, all switches are in the high impedance OFF-state, independent of A0 and A1. VDD and VSS are the supply voltage connections for the digital control inputs (A0, A1 and E). The VDD to VSS range is 3 to 15 V. The analogue inputs/outputs (Y0 to Y3, and Z) can swing between VDD as a positive limit and VEE as a negative limit. VDD − VEE may not exceed 15 V.
The HEF4052B is a dual 4‑channel analogue multiplexer/demultiplexer with common channel select logic. Each section provides four independent inputs/outputs (Y0‑Y3) and a common I/O (Z), controlled by two address inputs (A0, A1) and an active‑LOW enable input (E). The device operates with a supply voltage range of 3 V to 15 V and supports both analogue and digital multiplexing functions.
The datasheet includes detailed pin configurations, DC and AC electrical characteristics, propagation delays, ON‑resistance values, and application notes such as signal gating and break‑before‑make operation. It also provides test set‑up diagrams and typical performance curves for various supply voltages.
