Intersil Quad SPST Switch, 35 Ohm, 16-Pin DIP

The Intersil Quad SPST Switch is a precision integrated circuit designed for high-reliability signal switching and routing applications. It offers a robust supply voltage range from 5V to 34V for single-supply operation, or ±5V to ±20V for dual-supply setups, providing excellent flexibility for various analogue and digital circuit designs. With a low on-resistance of just 35 ohms maximum, it ensures minimal signal attenuation and power loss, making it ideal for high-fidelity audio, instrumentation, and data acquisition systems where signal integrity is paramount.

Housed in a compact 16-pin Dual In-line Package (DIP), this IC is perfectly suited for prototyping on breadboards or for straightforward integration into through-hole PCB designs. It features a Single-Pole, Single-Throw (SPST) switch configuration, providing a simple and effective break-before-make switching action. The device is engineered to perform reliably across a broad industrial temperature range from -40°C to +85°C, ensuring stable operation in demanding environments, from outdoor equipment to automotive and industrial control systems.
