MAX395CWG+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX395CWG+ is an 8-channel, serially controlled, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply from +2.7V to +16V or dual supplies from ±2.7V to ±8V. The device features a maximum on-resistance of 100Ω with a channel-to-channel match of 5Ω and flatness of 10Ω over the signal range. Turn-on and turn-off times are typically 400ns. It includes an asynchronous RESET input and supports daisy-chaining via its DOUT pin. The component is housed in a 24-pin Wide SOIC package.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Serial interface compatible with SPI, QSPI, and Microwire standards
• Eight individually controlled SPST switches with rail-to-rail signal handling
• Asynchronous reset function for immediate switch deactivation
• Pin-compatible with industry-standard MAX335

Analog Switches, Multiplexers, Demultiplexers Applications

• Serial data-acquisition systems
• Industrial and process-systems control
• Audio signal routing
• Avionics equipment
• Automated test equipment (ATE)

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'WG+' indicates the lead-free RoHS-compliant variant in the Wide SOIC package. Confirm the temperature grade corresponds to the 'C' designation (0°C to +70°C). Ensure the ordering information matches the current manufacturer datasheet as product availability and specifications may change.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a low-voltage, serially controlled multiplexer is required. It serves as a direct replacement for two cascaded MAX391 quad switches. Consider the 100Ω on-resistance and 400ns switching speed against application requirements. Verify that the digital logic thresholds align with the system's TTL/CMOS compatibility needs at the operating voltage.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX395 series of serially controlled analog switches. It is electrically equivalent to two MAX391 devices managed by a shared serial interface. The CWG+ designation specifies the commercial temperature range and the 24-pin Wide SOIC surface-mount package configuration.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX395EWG+ is a verified industrial-grade substitute offering an extended temperature range of -40°C to +85°C while maintaining identical electrical characteristics and pinout.
