MAX359CPE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX359CPE is a dual-channel analog switch integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It features two independent SP4T (Single-Pole Four-Throw) multiplexer circuits housed in a 16-pin PDIP package. The device operates on a dual supply voltage ranging from ±4.5V to ±20V. Key electrical specifications include a maximum on-resistance of 400 ohms, a channel-to-channel matching of 4 ohms, and typical switching times of 500ns for both turn-on and turn-off. Leakage current is specified at a maximum of 20pA, with a charge injection of 1.5pC. The component supports an operating temperature range of 0°C to 70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CPE' against official manufacturer documentation to confirm the PDIP package type and commercial temperature grade. Ensure compatibility with existing board layouts designed for 16-pin DIP footprints. Cross-reference the part number with Analog Devices or Maxim Integrated catalogs to confirm current production status and availability channels before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual independent 4-to-1 multiplexing is required with low leakage characteristics. Compare the 400-ohm on-resistance against application requirements; if lower resistance is needed, consider alternatives like the MAX339 series. Verify that the ±4.5V to ±20V supply range aligns with the system power design and that the 0°C to 70°C operating temperature meets environmental constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX359 belongs to the MAX338/MAX339 family of fault-tolerant analog switches. This series is designed for robust operation in harsh environments. The MAX359 specifically offers SP4T functionality, distinguishing it from simpler SPST or SPDT variants in the same product line. It serves as a bridge between basic switching needs and more complex multiplexing requirements without requiring multiple discrete components.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

MAX339CPE+ is a direct functional substitute within the same family, offering identical SP4T configuration and similar electrical parameters. Verify pinout compatibility and package dimensions before substitution. Other alternatives may include the MAX350 series for lower on-resistance, though package and supply voltage differences must be evaluated.
