MAX359EWE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX359EWE is a dual analog switch manufactured by Analog Devices Inc./Maxim Integrated, housed in a 16-SOIC surface-mount package. It contains two independent SP4T (Single Pole, Four Throw) switching circuits, providing four-to-one multiplexing functionality per channel. The device operates on dual supplies ranging from ±4.5V to ±18V. Key electrical specifications include a maximum on-resistance of 1.8kΩ and typical switch times of 300ns for both turn-on and turn-off transitions. The maximum leakage current is specified at 10µA. The component supports an operating temperature range of 0°C to 75°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' against official documentation to confirm the commercial temperature grade and lead-free status. Ensure the 16-SOIC footprint matches the target PCB layout. Cross-reference the manufacturer's latest datasheet revision to validate pinout compatibility and absolute maximum ratings before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual independent 4:1 switching is required within a compact surface-mount form factor. The 1.8kΩ on-resistance suits applications where low power consumption is prioritized over minimal signal attenuation. Verify that the ±4.5V minimum supply voltage aligns with the system's available power rails and that the 300ns switching speed meets the timing requirements of the target application.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX359 belongs to the Maxim Integrated family of fault-protected analog multiplexer switches. This series is designed for robust performance in harsh environments, offering protection against overvoltage conditions. The EWE variant specifically denotes the commercial temperature range and SOIC packaging, distinguishing it from military or wider temperature options within the broader MAX359 product line.
