Maxim Integrated MAX351CSE+T - Precision Quad SPST Switches

The MAX351CSE+T from Maxim Integrated is a high-performance, quad single-pole single-throw (SPST) analog switch that offers precision operation with a low-voltage single supply. Designed for applications that require high accuracy and reliability, this switch is an excellent choice for multiplexing and signal routing in data acquisition systems, communication devices, and medical equipment.

Constructed with Maxim’s proprietary silicon-gate process, the MAX351CSE+T provides low on-resistance (R<sub>ON) of 35Ω (max) over the entire signal range, ensuring minimal signal distortion and power loss. This is complemented by its low leakage current and high off-isolation, which contribute to the preservation of signal integrity and reduce crosstalk between channels.

This device operates with a single supply voltage ranging from +4.5V to +30V, or a dual supply from ±4.5V to ±20V, making it versatile for various circuit configurations. The MAX351CSE+T is also characterized by its fast switching speeds, with t<sub>ON of 175ns and t<sub>OFF of 145ns, allowing for quick transitions that are essential in time-sensitive applications.

The switches in the MAX351CSE+T are designed with break-before-make switching action, which prevents momentary shorting when switching from one channel to another. Each switch is controlled by a separate logic input that accepts TTL and CMOS voltage levels, providing ease of interface with digital systems.

Maxim Integrated packages this high-quality switch in a 16-pin narrow SO package, which is both space-efficient and suitable for surface-mount technology (SMT), aiding in the design of compact and high-density electronic assemblies. The “T” suffix indicates that the product is offered in tape and reel packaging, which is ideal for automated manufacturing processes.

In summary, the MAX351CSE+T is a reliable and precise quad SPST switch that offers low on-resistance, low leakage, high off-isolation, and fast switching speeds. Its compatibility with a wide range of supply voltages and logic levels, along with its compact packaging, make it an excellent choice for engineers seeking a high-quality switch for their sophisticated electronic designs.
