MAX4530CWP

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4530CWP is a low-voltage CMOS analog multiplexer configured as an 8-channel mux in a 20-pin SO package. It operates from single supplies of +2V to +12V or dual supplies of ±2V to ±6V. The device features two complementary switch-enable inputs and address latching, with on-resistance matched between switches to 8 Ω max. Off-leakage current is 1nA at +25°C. Digital inputs have 0.8V and 2.4V logic thresholds for TTL/CMOS compatibility.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CWP' indicates the commercial temperature range (0°C to +70°C) and SOIC-20 package configuration. Confirm RoHS compliance status through official manufacturer documentation, as historical batches may vary. Ensure the source document explicitly lists this part number as available or end-of-life before initiating procurement processes.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4530CWP when an 8-channel multiplexing function is required within a standard DIP footprint. Verify that the operating voltage range of +2V to +12V aligns with system power rails. Consider the 150 Ω maximum on-resistance for signal integrity requirements. Ensure the 0°C to +70°C temperature rating meets environmental constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4530CWP belongs to the MAX4530/MAX4531/MAX4532 family of low-voltage CMOS analog switches. These devices are designed as pin-compatible replacements for the 74HC4351, 74HC4352, and 74HC4353 series. The CWP suffix specifically denotes the commercial temperature grade and the 20-pin Small Outline package type.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include the MAX4530CPP (Plastic DIP) and MAX4530CAP (SSOP). For extended temperature ranges, the MAX4530EWP (-40°C to +85°C) is available. Verify pinout compatibility if replacing with non-Maxim equivalents.
