MAX359C/D

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX359C/D is a dual fault-protected analog multiplexer switch featuring two independent SP4T circuits. It operates on dual supplies ranging from ±4.5V to ±18V or single supplies up to 36V. The device provides high isolation and low leakage current, with an off-state leakage of 10µA maximum. On-resistance is specified at 1.8kΩ for the C grade and 2.2kΩ for the D grade. Switching times are typically 300ns for both turn-on and turn-off. It is available in 16-pin SOIC packages for surface mount applications.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix (C or D) to confirm resistance tolerance grades. Confirm package type matches design requirements, as variations exist between SOIC and CDIP formats. Check RoHS compliance status for environmental regulations. Ensure supply chain sources provide original manufacturer documentation to validate authenticity and traceability.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the C variant for lower on-resistance specifications suitable for precision applications. Choose the D variant if slightly higher resistance is acceptable for cost optimization. Verify voltage ratings align with system power rails. Consider thermal dissipation limits when operating near maximum temperature ranges.
