MAX369CPN

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX369CPN is a dual-channel analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features two single-pole four-throw (SP4T) switches within an 18-pin PDIP package. The device operates on dual supplies ranging from ±4.5V to ±18V. Key electrical parameters include a maximum on-resistance of 1.8kΩ, channel-to-channel matching of 180Ω, and a charge injection of 55pC. Switching times are specified with a maximum Ton of 1.5µs and Toff of 1µs. Leakage current is limited to 5nA maximum, with off-state capacitance values of 5pF and 12pF. The component supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CPN' against official documentation to confirm pinout and package type accuracy. Confirm RoHS compliance status as historical data indicates non-compliance for some variants. Check for obsolescence notices or lifecycle changes prior to procurement planning.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual independent SP4T switching is required with high voltage tolerance. Ensure the 1.8kΩ on-resistance meets system impedance requirements. Verify that the 18-pin DIP package fits the mechanical constraints of the target design.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX369 belongs to the MAX368/MAX369 family of fault-protected analog multiplexers. These devices are designed for robust performance in harsh environments. The CPN variant specifically denotes the plastic DIP package option within this product line.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Check for direct pin-compatible replacements such as the MAX368 series if single-channel functionality suffices. Verify electrical parameter equivalence for any cross-brand substitutes.
