MAX337EWI+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX337EWI+T is a monolithic CMOS analog multiplexer featuring two independent 8-channel switches in a 28-pin Wide SOIC package. It connects one of eight inputs to a common output using a 3-bit binary address. The device operates from single +4.5V to +30V or dual ±4.5V to ±20V supplies. Key electrical parameters include a maximum on-resistance of 700Ω, typical charge injection of 10pC, and transition times up to 600ns. Control inputs are TTL compatible (0.8V to 2.4V). It offers extremely low off-leakage currents (<20pA at +25°C) and ESD protection exceeding 2000V.

• Precision signal routing networks
• Test and measurement equipment

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EWI' corresponds to the Wide SO-28 package and the '+T' indicates tape-and-reel delivery format. Confirm the 'E' grade ensures operation within the -40°C to +85°C temperature range. Cross-reference the manufacturer's ordering information to ensure compatibility with current RoHS compliance standards before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual 8-channel topology is required rather than a single 16-channel switch. Ensure the application voltage does not exceed the specified limits for the Wide SOIC package. Verify that the 700Ω maximum on-resistance meets the system's signal integrity requirements compared to lower-resistance alternatives.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX336/MAX337 family of low-leakage CMOS analog multiplexers. It serves as a pin-compatible upgrade for industry-standard DG507 devices. The MAX337 specifically provides dual 8-channel functionality, whereas the MAX336 provides a single 16-channel configuration within the same package footprint.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX337EWI+ is a direct pin-compatible replacement for the DG507. Designers should verify that the upgraded leakage specifications and ESD protection levels align with the original design constraints.
