MAX396CWI

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX396CWI is a precision, low-voltage CMOS analog multiplexer featuring 16 single-ended channels in a 28-pin Wide SO package. It operates with a single supply from +2.7V to +15V or dual supplies of ±2.7V to ±8V. Key electrical characteristics include a maximum on-resistance of 100Ω at +25°C and 125Ω across the full temperature range, with channel-to-channel matching guaranteed within 6Ω. The device exhibits low charge injection (max 5pC) and fast switching speeds, with transition times under 250ns. Input off-leakage current remains below 1nA at +85°C, ensuring high signal integrity for data acquisition and signal routing applications.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range of 0°C to +70°C. Confirm the 'W' suffix corresponds to the 28-pin Wide SOIC package format. Ensure the datasheet revision matches the required design specifications. Check for RoHS compliance status if environmental regulations apply to the target assembly. Validate pinout alignment with existing PCB footprints before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX396CWI when a 16-channel configuration is required rather than the dual 8-channel MAX397 variant. Choose this part for designs needing precise resistance matching between channels. Consider the operating temperature range; the 'C' suffix is limited to commercial grades. Evaluate power supply constraints to ensure operation within the 2.7V to 15V single-supply window. Verify that the 100Ω on-resistance meets the voltage drop requirements of the application.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX396 belongs to the Maxim Integrated low-voltage CMOS analog switch family. It serves as a direct replacement for legacy parts like the DG406. The device utilizes silicon-gate technology to achieve low power consumption and fast switching. It is designed for applications requiring high channel density and signal fidelity in compact form factors.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX396EWI offers identical functionality but supports an extended industrial temperature range of -40°C to +85°C. The MAX397 provides dual 8-channel architecture instead of 16 single-ended channels. Legacy equivalents include the DG406 and MAX306, which share pinouts.
