MAX4530C/D

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4530C/D is a low-voltage CMOS analog multiplexer configured as an 8-channel mux. It operates from single supplies of +2V to +12V or dual supplies of ±2V to ±6V. The device features rail-to-rail signal handling, with on-resistance (RON) typically at 75Ω with ±5V supplies and 150Ω with +5V supply. On-resistance matching between channels is limited to 8Ω maximum. Off-leakage current is specified at 1nA at +25°C and 50nA at +85°C. Digital inputs support TTL/CMOS compatibility with logic thresholds of 0.8V and 2.4V. The component includes two complementary switch-enable inputs and address latching functionality.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range of 0°C to +70°C. Confirm package availability in SOIC-20 or DIP-20 formats. Check for RoHS compliance status if required by local regulations. Ensure the ordering code matches the exact pin configuration needed for the target PCB layout.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when an 8-channel multiplexing function is required within a standard 20-pin footprint. Consider the on-resistance flatness and leakage specifications against the application's signal integrity requirements. Verify that the operating voltage range aligns with the system's available power rails. Evaluate thermal dissipation capabilities based on the chosen package type and ambient temperature conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4530/MAX4531/MAX4532 family of low-voltage CMOS analog switches. The MAX4530 specifically provides an 8:1 multiplexer configuration, while sibling parts offer different channel counts or SPDT switch arrangements. All members share pin compatibility with legacy 74HC series logic, facilitating direct upgrades in existing designs.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements include other MAX4530 variants with extended temperature ranges (e.g., MAX4530E). Cross-family alternatives like the ADG1408 may require schematic adjustments due to differing control logic or performance characteristics.
