MAX396CWI+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX396CWI+T 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 of 100Ω at +25°C (max 125Ω over temperature), channel-to-channel matching within 6Ω, and flatness within 10Ω. The device exhibits low off-leakage current (<1nA at +85°C) and fast switching speeds with transition times under 250ns. It maintains TTL/CMOS logic compatibility and offers ESD protection exceeding 2000V.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the 'C' designation aligns with the required commercial operating temperature range of 0°C to +70°C. Ensure the '+T' suffix corresponds to RoHS compliance standards as defined by Analog Devices. Cross-reference the datasheet revision date to confirm parameter validity against your design requirements.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring precise analog signal routing with minimal distortion. The low on-resistance variation ensures consistent performance across all 16 channels. Verify that the supply voltage range matches your system's power architecture, as performance guarantees apply strictly between 2.7V and 16V. Consider the 28-pin Wide SO package dimensions for PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX396/MAX397 family of low-voltage CMOS analog multiplexers. The MAX396 variant provides 16 single-ended channels, whereas the MAX397 offers dual 8-channel configurations. Both share identical pinouts and core electrical characteristics, differing primarily in channel count and internal configuration.
