MAX394EPP+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX394EPP+ is a precision, low-voltage, quad single-pole/double-throw (SPDT) analog switch in a 20-pin Plastic DIP package. It operates with bipolar supplies from ±2.7V to ±8V or a single supply of +2.7V to +15V. The device features an on-resistance of less than 35Ω at +25°C and guaranteed matching within 2Ω between channels. Turn-on time is typically 82ns and turn-off time is typically 57ns. Quiescent current is less than 1μA. Logic inputs are TTL and CMOS compatible.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Low on-resistance with guaranteed channel-to-channel matching
• TTL and CMOS logic input compatibility
• Rail-to-rail analog signal handling capability
• Pin-compatible replacement for the MAX333 and MAX333A

• Test Equipment
• Communications Systems
• Audio Signal Routing
• Portable Instruments

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component against official Analog Devices documentation to confirm the specific E-series temperature rating (-40°C to +85°C) and the 20-pin Plastic DIP physical form factor. Ensure that the ordering suffix matches the required lead finish and RoHS compliance status as defined in the manufacturer's current ordering guide.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when a quad SPDT configuration is required for low-voltage applications. The E-grade variant provides extended industrial temperature coverage compared to the C-grade commercial version. Verify that the system power rails fall within the specified ±2.7V to ±8V dual supply range or +2.7V to +15V single supply range.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the Maxim Integrated MAX394 family of precision analog switches. It serves as a direct pin-compatible upgrade to the older MAX333 and MAX333A series, offering significantly lower on-resistance and improved switching speeds while maintaining similar footprint requirements for PCB layout reuse.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX394CPP+ is the commercial grade equivalent operating from 0°C to +70°C. The MAX394EWP+ offers the same electrical performance but utilizes a Wide SOIC package instead of the Plastic DIP format.
