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 +16V or dual supplies of ±2.7V to ±8V. Key electrical parameters include a maximum on-resistance (RON) 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), transition times under 250ns, and off-leakage currents below 1nA at +85°C. Logic inputs are TTL/CMOS compatible, requiring a logic high of ≥2.4V and low of ≤0.8V.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the ordering suffix 'WI+' confirms the Wide SOIC-28 package and commercial temperature range (+0°C to +70°C). Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure supply voltage sequencing adheres to absolute maximum ratings to prevent damage during power-up or power-down cycles.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX396CWI+ when a 16-channel configuration is required for single-ended signal routing. Choose this part over the MAX397 if differential or dual 8-channel operation is not needed. Verify that the application signal range fits within the V+ to V- limits and that the 100Ω on-resistance meets system accuracy requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX396/MAX397 family of low-voltage CMOS analog multiplexers manufactured by Analog Devices Inc./Maxim Integrated. The MAX396 variant specifically provides 16 channels, whereas the MAX397 offers dual 8-channel configurations. Both share identical pinouts and core performance characteristics, differing primarily in channel count and internal decoder logic.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed pin-compatible replacements include the MAX306, DG406, and DG506A. These devices offer similar functionality but may differ in specific electrical parameters such as on-resistance or leakage current. Verify datasheet specifications for the substitute part to ensure compatibility with existing circuit designs.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the maximum on-resistance flatness for the MAX396CWI+?

The on-resistance flatness (RFLAT(ON)) is guaranteed to be a maximum of 10Ω at +25°C and 13Ω across the operating temperature range.

How does the MAX396 handle overvoltage conditions?

Signals on any terminal are clamped by internal diodes. For protection against external overvoltage, external blocking diodes can be added in series with the supply pins, though this reduces the usable analog signal range.

Is the MAX396CWI+ suitable for single-supply operation?

Yes, it operates with a single supply ranging from +2.7V to +16V. When using a single supply, the V- pin should be connected to GND.
