NEXPERIA Quad SPST Analogue Switch IC, 350 Ohm, 14-Pin SOIC

The NEXPERIA HEF4066BT is a high-performance, quad single-pole single-throw (SPST) analogue switch integrated circuit. Designed for precision signal routing, each of the four independent switches features two input/output terminals (nY and nZ) and an active high enable input (nE). When the enable input (nE) is driven low, the corresponding analogue switch is turned off, providing reliable signal isolation.

A key advantage of this IC is its significantly lower on-resistance compared to similar devices like the HEF4016B, with which it is pin-compatible. This low on-resistance, with a maximum of 350 ohms, remains relatively constant across the full input signal range, ensuring minimal signal distortion and attenuation. This makes it an excellent choice for applications demanding high signal integrity.

The device offers fully static operation and standardised symmetrical output characteristics for consistent performance. Inputs and outputs are protected against electrostatic discharge (ESD), enhancing reliability in sensitive electronic environments. It complies with the JEDEC standard JESD 13-B, affirming its quality and interoperability in professional designs.

Supplied in a compact 14-pin SOIC (Small Outline Integrated Circuit) package, it is designed for efficient surface-mount assembly on printed circuit boards (PCBs). It operates from a wide supply voltage range of 4.5V to 15.5V and can function in temperatures from -40°C to 70°C, making it suitable for a broad spectrum of industrial and commercial applications.

With its robust construction, protected inputs, and stable electrical characteristics, the NEXPERIA HEF4066BT provides a dependable and high-quality solution for analogue signal switching needs.
