MAX359EJE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX359EJE is a dual analog switch manufactured by Analog Devices Inc./Maxim Integrated, housed in a 16-CDIP package. It integrates two independent SP4T (Single-Pole Four-Throw) switching circuits, functioning as 4:1 multiplexers. The device operates on a dual supply voltage ranging from ±4.5V to ±18V. Key electrical specifications include a maximum on-resistance of 2.2 kΩ and a leakage current of 10 µA when off. Switching times are specified with a typical turn-on time of 700 ns and a turn-off time of 1.5 µs. The component is designed for industrial temperature ranges, operating between -55°C and +125°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Dual-channel architecture providing two independent 4:1 multiplexer functions within a single integrated circuit.
• SP4T configuration allows flexible signal routing across four input channels per switch.
• Robust construction suitable for demanding environments with an extended industrial temperature range.
• High isolation characteristics ensure minimal signal interference between active and inactive paths.

Analog Switches, Multiplexers, Demultiplexers Applications

• Signal routing in test and measurement instrumentation
• Data acquisition systems requiring multi-channel selection
• Industrial control interfaces for sensor switching
• Communication equipment signal path management

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix JE against official manufacturer documentation to confirm the ceramic DIP package and military/industrial grade specifications. Ensure compatibility with existing board layouts for 16-lead CDIP footprints. Cross-reference lead availability and authenticity through authorized distribution channels to prevent counterfeit components. Confirm RoHS status if required by project regulations, noting that some legacy variants may differ.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high channel count per IC is required without increasing board space significantly. The SP4T topology is ideal for applications needing to select one of four signals per channel. Consider the relatively high on-resistance compared to lower-voltage CMOS switches; ensure the application can tolerate the associated voltage drop or power dissipation. Verify that the ±4.5V to ±18V supply range aligns with the system's available power rails.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX359 belongs to a family of analog multiplexer switches from Maxim Integrated, now part of Analog Devices. This series typically offers various configurations including SPDT and SP4T options in different packages. The EJE variant specifically denotes the ceramic dual in-line package version, often associated with higher reliability or specialized environmental ratings compared to standard plastic equivalents.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes may include other MAX359 variants with different package styles such as MAX359CWE+ for surface mount applications. Check pinout compatibility before substitution. Alternative manufacturers may offer similar SP4T dual switches, but verify on-resistance, leakage, and switching speed parameters to ensure functional equivalence.
