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 rail-to-rail signal handling, with on-resistance (RON) typically ranging from 75Ω at ±5V to 150Ω at +5V single supply. 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. Switching times include tON/tOFF of 150ns/120ns at ±4.5V. The component includes address latching and two complementary enable inputs.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range of 0°C to +70°C. Confirm the 'WP' designation corresponds to the 20-pin Small Outline package. Ensure the '+T' suffix requirement is met if reel packaging is necessary, as standard ordering may vary by distributor lot specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when pin compatibility with legacy 74HC series multiplexers is required. Choose the C-grade version for commercial temperature environments. Verify that the single-supply voltage range meets the system's power constraints, noting that on-resistance increases at lower voltages.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4530/MAX4531/MAX4532 family of low-voltage CMOS analog switches. While the MAX4531 offers two 4-channel muxes and the MAX4532 provides three SPDT switches, the MAX4530 specifically implements a single 8-channel multiplexer configuration within the same 20-pin footprint.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the MAX4530 handle analog signals relative to the supply rails?

The device supports Rail-to-Rail signal handling, allowing analog signals to swing from the negative supply rail to the positive supply rail without clipping.

What is the logic threshold behavior for digital inputs?

Digital inputs feature 0.8V and 2.4V logic thresholds, ensuring compatibility with both TTL and CMOS logic families when using ±5V or a single +5V supply.

Does the device support address latching?

Yes, the MAX4530 includes address latching functionality controlled by the LE (Latch Enable) input, allowing channel selection without continuous address driving.
