MAX378CPE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX378CPE+ is a high-voltage, fault-protected analog multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It features an 8-channel single-ended (1-of-8) configuration housed in a 16-pin Plastic DIP package. The device operates from dual power supplies ranging from ±4.5V to ±18V and supports continuous input voltages up to ±60V with supplies active, or ±75V when supplies are off. Key electrical parameters include an on-resistance of 2.0kΩ to 3.5kΩ, access time of 0.5µs to 1.0µs, and break-before-make delay of 25ns to 200ns. It ensures TTL and CMOS compatibility with digital thresholds at 0.8V and 2.4V.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Series N-channel/P-channel/N-channel structure provides significant fault protection against overvoltage conditions.
• All channels automatically turn off when power supplies are removed, limiting leakage current to nanoamperes.
• Break-before-make switching action prevents simultaneous connection of multiple inputs to the output.
• Latchup-proof construction ensures reliability under extreme operating conditions.

Analog Switches, Multiplexers, Demultiplexers Applications

• Data Acquisition Systems
• Industrial and Process Control Systems
• Avionics Test Equipment
• Signal Routing Between Systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'CPE' corresponds to the required plastic DIP package and commercial temperature range. Request official datasheets and RoHS compliance documentation prior to purchase to ensure alignment with project specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring robust fault protection against high-voltage transients. Ensure the system design accommodates the specified ±4.5V to ±18V supply range. Verify that the 16-pin DIP package fits the target PCB layout constraints. Consider the thermal dissipation characteristics if operating near maximum temperature limits.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX378/MAX379 family of high-voltage, fault-protected analog multiplexers. The MAX378 variant specifically offers 8 single-ended channels, whereas the MAX379 provides 4 differential channels. Both share identical fault protection mechanisms and pinout configurations within their respective channel counts.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements must maintain the 16-pin DIP footprint and fault-protection capabilities. Verify that any substitute device supports the same ±60V continuous input voltage rating and compatible logic thresholds for seamless integration into existing designs.
