MAX389CPN+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX389CPN+ is a high-voltage analog multiplexer switch IC manufactured by Analog Devices Inc./Maxim Integrated. It features two independent SP4T (single-pole four-throw) circuits, providing a total of eight channels in an 18-pin PDIP package. The device supports dual supply voltages ranging from ±4.5 V to ±18 V. Key electrical parameters include a maximum on-resistance of 3 kOhms and a channel-to-channel matching of 300 Ohms. Switching performance is characterized by a maximum turn-on time of 1.5 µs and a turn-off time of 1 µs. The component operates within a temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CPN+' against official manufacturer documentation to confirm pinout and environmental compliance. Check current availability status as distribution may be limited or restricted in certain regions. Ensure the procurement source provides valid traceability for this discontinued or end-of-life product variant.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual isolated 4:1 switching paths are required with high voltage tolerance. Compare on-resistance and charge injection specifications against system requirements. Consider the 18-PDIP form factor if through-hole assembly is mandated over surface-mount alternatives.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX388/MAX389 series of high-voltage analog switches. It shares architectural similarities with the MAX388 but offers a different channel configuration. Both devices utilize similar packaging and support comparable dual-supply operating ranges within the Maxim Integrated portfolio.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations
