HEF4051B 8-channel analog multiplexer/demultiplexer Rev. 13 29 July 2021 Product data sheet 1. General description The HEF4051B is a single-pole octal-throw analog switch (SP8T) suitable for use in analog or digital 8:1 multiplexer/demultiplexer applications. The switch features three digital select inputs (S1, S2 and S3), eight independent inputs/outputs (Yn), a common input/output (Z) and a digital enable input (E). When E is HIGH, the switches are turned off. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of V . CC 2. Features and benefits Wide supply voltage range from 3.0 V to 15.0 V CMOS low power dissipation High noise immunity Fully static operation 5 V, 10 V, and 15 V parametric ratings Standardized symmetrical output characteristics Complies with JEDEC standard JESD 13-B ESD protection: HBM JESD22-A114F exceeds 2000 V MM EIA/JESD22-A115-A exceeds 200 V Specified from -40 C to +85 C and -40 C to +125 C 3. Applications Analog multiplexing and demultiplexing Digital multiplexing and demultiplexing Signal gating 4. Ordering information Table 1. Ordering information All types operate from -40 C to +125 C.
