HEF4066B Quad single-pole single-throw analog switch Rev. 10 21 December 2021 Product data sheet 1. General description The HEF4066B is a quad single pole, single throw analog switch. Each switch features two input/output terminals (nY and nZ) and an active HIGH enable input (nE). When nE is LOW, the analog switch is turned off. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of V . DD 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 Inputs and outputs are protected against electrostatic effects Complies with JEDEC standard JESD 13-B ESD protection : HBM JESD22-A114F exceeds 2000 V MM JESD22-A115-B exceeds 200 V Specified from -40 C to +85 C and -40 C to +125 C 3.
