MAX389EPN+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX389EPN+ is a high-voltage analog multiplexer switch IC manufactured by Analog Devices Inc./Maxim Integrated. It features two independent SP4T (Single Pole, Four Throw) switching circuits within an 18-pin PDIP package. The device supports dual supply voltages ranging from ±4.5V to ±18V. Key electrical specifications include a maximum on-resistance of 3 kOhms, a channel-to-channel matching of 300 Ohms, and a maximum charge injection of 55pC. Switching times are specified with a maximum turn-on time of 1.5µs and a maximum turn-off time of 1µs. The component operates within a temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'PN+' against the official Analog Devices datasheet to confirm the PDIP-18 through-hole package and commercial temperature grade. Ensure compatibility with existing PCB footprints designed for standard DIP-18 components. Cross-reference the manufacturer's part number guide to validate that the '+' indicates RoHS compliance without altering functional pinouts or electrical characteristics compared to non-suffixed variants.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual high-voltage analog switches are required in a through-hole configuration. The 3 kOhm on-resistance suits applications where lower current precision is acceptable. Compare against the MAX389CWG+ for surface-mount alternatives. Verify that the ±4.5V minimum supply voltage aligns with the system power rails. Consider the 1.5µs switching speed for timing constraints in the target circuit design.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX389 belongs to the Maxim Integrated high-voltage multiplexer family, designed for robust analog signal routing. It complements other devices like the MAX384, which offers similar functionality but may differ in switching configuration or operating temperature ranges. The series is characterized by its ability to handle significant voltage differentials while maintaining signal integrity in industrial environments.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX389CPN+ serves as a direct equivalent within the same package and specification profile. For surface-mount requirements, the MAX389CWG+ provides identical electrical performance in a 24-SOIC package. Verify pinout compatibility before substitution.
