MAX4530CPP+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4530CPP+ is a low-voltage CMOS analog multiplexer configured as an 8-channel mux in a 20-pin plastic DIP package. 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 channels to a maximum of 8Ω, with a typical value of 75Ω at ±5V supplies. Off-leakage current is specified at 1nA at +25°C and 50nA at +85°C. Digital inputs are TTL/CMOS compatible with thresholds of 0.8V and 2.4V.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix CPP indicates the 20-pin Plastic DIP package variant. Confirm the C designation corresponds to the commercial temperature range of 0°C to +70°C. Ensure the datasheet revision matches the design requirements. Check for RoHS compliance status if required by the manufacturing process. Validate pinout compatibility with existing PCB footprints before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-channel multiplexing function is required with address latching capabilities. Consider the on-resistance flatness and leakage specifications for precision analog signal paths. Evaluate the supply voltage range against the system's available power rails. Verify that the digital logic levels align with the controlling microcontroller or FPGA outputs. Assess thermal dissipation requirements based on the chosen packaging and ambient operating conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4530/MAX4531/MAX4532 family of low-voltage CMOS analog switches. The MAX4530 specifically provides an 8:1 multiplexer configuration, whereas the MAX4531 offers two 4:1 muxes and the MAX4532 provides three SPDT switches. All variants share pin compatibility and core electrical characteristics within their respective channel counts.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements include other MAX4530 variants such as MAX4530EPP or MAX4530CWP, which offer different packages or extended temperature ranges while maintaining functional equivalence.
