MAX337CAI+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX337CAI+ is a dual 8-channel CMOS analog multiplexer in a 28-pin SSOP package. It connects one of eight inputs to a common output via 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 (single supply) or 500Ω (dual supply), off-leakage current less than 1.25nA, and charge injection of 10pC. Transition time is 600ns with a single supply. Control inputs are TTL compatible.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'AI+' confirms the 28-pin SSOP package and the commercial temperature range of 0°C to +70°C. Ensure the component meets lead-free/RoHS compliance requirements as indicated by the plus sign. Cross-reference the datasheet revision date to confirm parameter consistency before finalizing procurement specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when a dual 8-channel configuration is required rather than a single 16-channel unit. Verify that the application voltage does not exceed the +30V single-supply limit. Confirm that the 700Ω on-resistance is acceptable for the target signal levels and that the 0°C to +70°C operating range aligns with environmental conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX336/MAX337 family of monolithic CMOS analog multiplexers manufactured by Analog Devices/Maxim Integrated. The MAX337 variant specifically provides two independent 8-channel switches within a single 28-pin footprint, serving as a direct replacement for legacy DG507 designs while offering improved leakage characteristics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX337CAI+ is explicitly documented as a pin-compatible upgrade for the industry-standard DG507. Engineers replacing legacy hardware should verify that the DG507's performance limits meet the new device's specifications regarding leakage and on-resistance.

Analog Switches, Multiplexers, Demultiplexers FAQ

Is the MAX337CAI+ suitable for single-supply operation?

Yes, the device supports single-supply operation ranging from +4.5V to +30V. In this mode, the V- pin must be connected to GND.

What is the logic input compatibility of the MAX337CAI+?

All control inputs, including address and enable lines, are TTL compatible (0.8V to 2.4V) across the full specified temperature range and supply voltages.

How does the on-resistance vary with supply voltage?

On-resistance is specified at a maximum of 700Ω under single-supply conditions (+12V to +30V) and 500Ω under dual-supply conditions (-20V to +20V).
