MAX379CPE+G035

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX379CPE+G035 is a high-voltage, fault-protected analog multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It features four differential channels (2-of-8 configuration) and utilizes a series N-channel/P-channel/N-channel structure for significant fault protection. The device operates from ±4.5V to ±18V supplies with a typical power dissipation of less than 2mW. Key electrical parameters include an on-resistance of 2.0kΩ to 3.5kΩ, input leakage current of -1.0µA to 1.0µA under overvoltage conditions, and off-isolation of 50dB to 68dB at 100kHz. The component supports TTL and CMOS logic compatibility with digital thresholds of 0.8V and 2.4V.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix G035 against official manufacturer documentation to confirm availability and exact specifications. Confirm that the Plastic DIP package matches the design requirements. Ensure compliance with RoHS standards as indicated in the product datasheet before finalizing procurement decisions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high-voltage fault protection is required for differential signal routing. The MAX379 is suitable for applications needing isolation between sensors and downstream electronics. Consider the ±60V continuous input capability and the low power consumption characteristics for battery-operated or thermally constrained systems.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX379 belongs to the MAX378/MAX379 family of high-voltage, fault-protected analog multiplexers. While the MAX378 handles single-ended signals, the MAX379 is designed for differential inputs. Both share the same robust series FET protection scheme and operate within similar voltage ranges, providing industry-leading fault tolerance compared to first-generation devices.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements include other models within the MAX378/MAX379 family such as the MAX379EPE or MAX379MJE, which offer different temperature ranges but maintain identical pinouts and functionality.
