MAX379CPE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX379CPE is a high-voltage, fault-protected analog multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It features two differential channels (2-of-8 configuration) housed in a 16-pin Plastic DIP package. The device operates from supply voltages ranging from ±4.5V to ±18V with a typical power dissipation of less than 2mW. It provides significant fault protection using a series N-channel/P-channel/N-channel structure, allowing it to withstand continuous input voltages up to ±60V even when power supplies are off. Digital inputs are compatible with both TTL and CMOS logic levels without requiring pull-up resistors.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Series FET switching architecture ensures all switches turn off when power supplies are removed, limiting leakage currents to nanoamperes.
• Break-before-make operation prevents simultaneous connection of multiple input channels to the output.
• Latchup-proof construction guarantees robust performance under various electrical stress conditions.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'CPE' corresponds to the 16-pin Plastic DIP package and the commercial temperature range of 0°C to +70°C. Confirm that the component meets the required environmental standards for the intended deployment environment before finalizing procurement decisions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when differential signal routing is required within a system utilizing up to eight input pairs. Ensure the application voltage does not exceed the ±18V supply limit and verify that the ±60V fault protection capability aligns with the maximum expected transient or steady-state overvoltage conditions present in the circuit design.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX378/MAX379 family of high-voltage, fault-protected analog multiplexers. While the MAX378 provides eight single-ended channels, the MAX379 variant specifically offers two differential channels. Both share identical fault protection mechanisms and pinout compatibility within their respective channel counts.
