MAX339CSE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX339CSE+T is a dual 4-channel CMOS analog multiplexer in a 16-pin Narrow SO package. It operates from single supplies of +4.5V to +30V or dual supplies of ±4.5V to ±20V. The device features a maximum on-resistance of 650Ω at +25°C and 500Ω across the full temperature range. Off-leakage current is less than 20pA at +25°C, with charge injection typically at 1.5pC. Transition time is 500ns maximum. Control inputs are TTL compatible (+0.8V to +2.4V). ESD protection exceeds 2000V per method 3015.7.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range of 0°C to +70°C. Confirm the '+T' designation corresponds to reel packaging. Ensure the Narrow SO-16 footprint matches the design requirements. Cross-reference the manufacturer's ordering information to confirm availability status for this specific variant.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual 4-channel switching is required within a 16-pin narrow SOIC footprint. It serves as a pin-compatible upgrade for industry-standard DG509A devices. Consider the 650Ω on-resistance limit for high-impedance signal paths. Verify that the single-supply voltage range up to +30V aligns with the system power architecture.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX338/MAX339 family of monolithic CMOS analog multiplexers. The MAX339 specifically provides two independent 4-to-1 multiplexer channels. It shares the same low-leakage design philosophy and pinout compatibility as the MAX338, which offers an 8-channel configuration in the same package.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX339CSE+ is a direct pin-compatible replacement for the DG509A. For applications requiring lower leakage but higher on-resistance, the MAX329 is a similar alternative.
