MAX4511CPE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4511CPE+ is a quad, single-pole/single-throw (SPST) analog switch featuring fault protection and rail-to-rail signal handling. It operates with dual supplies from ±4.5V to ±18V or a single supply between +9V and +36V. The device provides four separately controlled switches housed in a 16-pin Plastic DIP package. On-resistance is typically 175Ω max at ±15V supplies, with a maximum match of 10Ω between channels. Off-leakage current is 0.5nA at +25°C. Fault-protected terminals handle up to ±36V during operation and ±40V when powered off.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Fault-protected inputs and outputs allow safe handling of overvoltage conditions without disrupting the load voltage.
• Rail-to-Rail signal capability ensures unambiguous output transitions during power-up, power-down, and fault events.
• TTL- and CMOS-compatible logic thresholds simplify interface requirements across various supply voltages.
• Pin-compatible design facilitates direct replacement for industry-standard non-fault-protected switches.

• Data Acquisition Systems
• Industrial and Process-Control Systems
• Avionics
• Redundant/Backup Systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CPE+' corresponds to the commercial temperature range and plastic DIP packaging. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure input logic levels align with the selected supply voltage to maintain compatibility.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when fault tolerance on signal lines is critical. Verify that the required on-resistance and leakage specifications meet system constraints. Consider the thermal dissipation capabilities of the Plastic DIP package relative to the expected operating temperature range.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4511/MAX4512/MAX4513 family of quad SPST analog switches. The MAX4511 variant specifically contains four normally closed switches. It serves as a robust alternative to legacy devices like the DG201/DG202/DG213 by adding integrated fault protection while maintaining identical pinouts.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements include the MAX4511ESE+ (Narrow SOIC) and MAX4511CSE+ (Narrow SO). Ensure the substitute maintains the same fault protection characteristics and package dimensions if board space is constrained.
