MAX4531EWP+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4531EWP+T is a low-voltage CMOS analog multiplexer switch IC configured as two independent 4-channel muxes. 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 8 Ω max with a maximum of 150 Ω. Off-leakage current is 1nA at +25°C and 50nA at +85°C. Digital inputs have 0.8V and 2.4V logic thresholds for TTL/CMOS compatibility. The EWP suffix indicates a 20-pin SOIC package with an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Confirm RoHS compliance status through manufacturer datasheets. Ensure the component matches the required pin configuration and electrical specifications for the target application before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual 4-channel multiplexing is required in a single package. Verify that the supply voltage range (+2V to +12V) aligns with system requirements. Consider the 150 Ω on-resistance and 1nA off-leakage characteristics for signal integrity needs. Ensure the 20-pin SOIC footprint fits the PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4531 belongs to the MAX4530/MAX4531/MAX4532 family of low-voltage CMOS analog switches. These devices are designed as direct replacements for standard 74HC series multiplexers while offering improved performance metrics such as lower leakage and wider supply ranges. The MAX4531 specifically provides two separate 4:1 mux sections within one integrated circuit.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include other members of the MAX453x family such as the MAX4530CWP+ (single 8-channel mux) or MAX4532EWP+ (three SPDT switches), provided the pinout and functional requirements match. Standard 74HC4351 equivalents may be used if higher on-resistance and leakage are acceptable.
