MAX337CPI+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX337CPI+ is a dual 8-channel CMOS analog multiplexer in a 28-pin Plastic DIP package. It connects one of eight inputs to a common output via a 3-bit binary address and supports single (+4.5V to +30V) or dual (±4.5V to ±20V) supplies. Key electrical parameters include a maximum on-resistance of 700Ω, off-leakage current under 1.25nA at the temperature extremes, and typical charge injection of 10pC. The device features TTL-compatible control inputs and operates within a commercial temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify that the component matches the specific commercial temperature grade (0°C to +70°C) required by the application design. Confirm the 28-pin Plastic DIP package format aligns with the target PCB footprint. Ensure supply voltages remain within the specified operational limits to maintain performance specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when a dual 8-channel configuration is necessary rather than a 16-channel layout. Consider the MAX337EPI+ variant if the system requires extended industrial temperature operation from -40°C to +85°C. Evaluate the on-resistance matching requirements against the 10Ω maximum specification for differential applications.

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 specifically provides two independent 8-channel switches, whereas the MAX336 offers a single 16-channel switch. Both share identical control logic and pinout architectures.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX337CPI+ serves as a direct pin-compatible replacement for the DG507. Designers should verify that alternative sources meet the same leakage and on-resistance guarantees before substitution.

Analog Switches, Multiplexers, Demultiplexers FAQ

Is the MAX337CPI+ compatible with TTL logic levels?

Yes, all control inputs are TTL compatible (0.8V to 2.4V) over the full specified temperature range and supply voltage range.

What is the maximum analog signal range for this device?

The analog signal range extends from V- to V+, allowing for rail-to-rail operation depending on the applied supply voltages.

Does the MAX337CPI+ support bidirectional signal flow?

Yes, the devices conduct current equally well in both directions, allowing them to function as either multiplexers or demultiplexers.
