MAX359CPE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX359CPE+ is a dual-channel analog switch IC 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 18V. Key electrical specifications include a maximum on-resistance of 3.5 kΩ, a typical turn-on time of 1 µs, and a typical turn-off time of 1.5 µs. The maximum off-state leakage current is specified at 20 pA. The component supports surface-mount or through-hole installation depending on the specific suffix variant, with the CPE+ designation indicating a commercial temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the exact ordering suffix against the manufacturer's official part numbering guide to confirm package type and temperature grade. Ensure the procurement source provides valid RoHS compliance documentation as required by project specifications. Cross-reference the manufacturer date code to ensure component freshness and storage integrity prior to assembly.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual independent 4:1 switching is required without external logic decoding. Compare the 3.5 kΩ on-resistance against application tolerance limits. Verify that the ±4.5V to 18V dual supply availability matches the system power design. Consider the 16-pin PDIP footprint constraints during PCB layout planning.

Analog Switches, Multiplexers, Demultiplexers Part Context
