MAX4531CWP+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4531CWP+ is a low-voltage CMOS analog multiplexer switch IC configured as two independent 4:1 multiplexers. It operates from a single supply of +2V to +12V or dual supplies of ±2V to ±6V. The device features address latching, two complementary enable inputs, and rail-to-rail signal handling. On-resistance is matched between channels to 8Ω max, with a maximum on-resistance of 75Ω at ±5V supplies. Off-leakage current is 1nA at +25°C. Digital inputs are TTL/CMOS compatible with 0.8V and 2.4V thresholds. The component is housed in a 20-pin SOIC package and supports an operating temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range (0°C to +70°C) and 'WP' denotes the 20-pin SOIC package. Confirm RoHS compliance status through official manufacturer documentation. Check for obsolescence notices as this component family may have discontinuation updates. Ensure pinout compatibility with existing PCB layouts before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4531CWP+ when two independent 4-channel multiplexing functions are required within a single package. Consider the ±5V supply configuration for optimal 75Ω on-resistance performance. Verify that the 0°C to +70°C operating range meets environmental requirements. Evaluate the need for address latching to reduce digital control lines compared to non-latched alternatives.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4531CWP+ belongs to the MAX4530/MAX4531/MAX4532 family of low-voltage CMOS analog switches. This series offers pin compatibility with standard 74HC logic equivalents while providing enhanced performance characteristics such as lower leakage and address latching. The C-grade variant specifically targets commercial applications requiring reliable switching within standard industrial temperature limits.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include other variants within the MAX4531 family such as MAX4531EWP+ for extended temperature ranges. Non-family replacements must match the 20-pin SOIC footprint and SP4T x 2 configuration. Verify voltage ratings and on-resistance specifications to ensure circuit compatibility.
