MAX395CNG+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX395CNG+ is an 8-channel, serially controlled, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates with dual power supplies ranging from ±2.7V to ±8V or a single supply between +2.7V and +16V. The device features a maximum on-resistance of 100Ω, matched between switches to 5Ω max, with flatness of 10Ω max over the signal range. Off leakage current is typically 0.1nA at +25°C. Switching times are up to 400ns for both turn-on and turn-off. It utilizes a SPI™/QSPI™/Microwire™ compatible serial interface and includes an asynchronous RESET input. The component is housed in a 24-pin Narrow Plastic DIP package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm temperature range and package type. Ensure that any additional characters in the part number do not alter the electrical specifications or pinout configuration. Cross-reference the manufacturer's latest datasheet to confirm current production status and compliance with relevant environmental standards before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a low-voltage, serially controlled multiplexing solution is required. It is suitable for applications needing rail-to-rail signal transmission with minimal channel-to-channel resistance mismatch. Consider the 24-pin PDIP package for through-hole mounting requirements. Verify that the system's digital logic levels are compatible with the specified TTL/CMOS thresholds under the intended supply voltage conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX395CNG+ belongs to the MAX395 series of serially controlled analog switches. It is electrically equivalent to two MAX391 quad switches managed by a serial interface. The device maintains pin compatibility with the industry-standard MAX335, facilitating direct upgrades or replacements in existing designs without requiring PCB layout modifications.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX395CNG+ is pin-compatible with the MAX335. Designers may consider these alternatives if sourcing constraints exist, provided the electrical characteristics meet the application requirements.
