MAX4531CWP

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4531CWP is a low-voltage CMOS analog multiplexer IC configured as two independent 4-channel muxes. It operates from single supplies of +2V to +12V or dual supplies of ±2V to ±6V. The device features address latching, two complementary switch-enable inputs, and rail-to-rail signal handling. On-resistance is matched between switches to 8 Ω max, with a maximum of 150 Ω. Off-leakage current is 1nA at +25°C. Digital inputs have 0.8V and 2.4V logic thresholds for TTL/CMOS compatibility. It is pin-compatible with industry-standard 74HC4351/74HC4352/74HC4353 devices.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CWP' corresponds to the 0°C to +70°C temperature range and 20-pin SO package. Confirm RoHS compliance status if required by project specifications. Check for obsolescence notices or end-of-life notifications from Analog Devices Inc./Maxim Integrated before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual 4-channel multiplexing is required in a single package. Ensure supply voltage requirements align with the +2V to +12V single or ±2V to ±6V dual supply ranges. Verify that the 150 Ω maximum on-resistance meets system impedance needs. Consider the 20-pin SO package dimensions for PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4531 is part of the MAX4530/MAX4531/MAX4532 family of low-voltage CMOS analog multiplexers. These devices share similar electrical characteristics and pinouts but differ in channel configuration. The MAX4531 specifically provides two 4:1 muxes, whereas the MAX4530 offers an 8-channel mux and the MAX4532 provides three SPDT switches.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include other variants within the MAX4530/MAX4531/MAX4532 family such as MAX4531EWP for extended temperature ranges. Industry-standard 74HC4352 equivalents may be considered for pin-compatible replacements, though electrical parameters like on-resistance and leakage may differ.
