MAX4531CWP+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4531CWP+T is a low-voltage CMOS analog multiplexer switch IC configured as two independent 4-channel multiplexers. It operates from single supplies 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 capabilities. On-resistance is matched between channels to 8 Ω maximum, with a typical value of 75 Ω at ±5V supplies. Off-leakage current is specified at 1nA at +25°C. Digital inputs are TTL/CMOS compatible with logic thresholds of 0.8V and 2.4V. The component provides 2kV ESD protection per Method 3015.7 and is housed in a 20-pin SOIC package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing this part number. Confirm that the C-grade designation corresponds to the commercial temperature range of 0°C to +70°C. Ensure compatibility with the 20-SOIC footprint during PCB layout. Check manufacturer documentation for any recent product change notices or end-of-life status updates.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for designs requiring pin-compatible upgrades to standard HC-series logic. Verify that the required on-resistance flatness and leakage currents meet system specifications under the intended operating voltage. Consider the thermal derating requirements for the SOIC package if high power dissipation is expected. Ensure the digital logic levels align with the 0.8V and 2.4V input thresholds.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the MAX4530/MAX4531/MAX4532 family of low-voltage CMOS analog switches. The MAX4531 specifically provides two 4-channel multiplexers, whereas the MAX4530 offers an 8-channel mux and the MAX4532 contains three SPDT switches. All members share identical pinouts and electrical characteristics, differing only in internal channel configuration.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include other variants within the MAX4530-32 family such as MAX4531EWP+ for extended temperature ranges. Cross-reference with standard 74HC4351 equivalents if pin compatibility is the primary constraint, though electrical performance may differ.
