Engineering Selection Recommendations

The MAX307EPI+ is the direct equivalent part for applications requiring dual 8:1 analog multiplexing with 100Ohm on-state resistance in a 28-DIP through-hole package. Both the main part and substitute are manufactured by Analog Devices Inc./Maxim Integrated with identical electrical specifications and mechanical form factors. Selection between equivalent units should be based on inventory availability, lead time, and procurement source. Both parts maintain active production status and full ROHS3 compliance with unlimited moisture sensitivity rating, ensuring suitability for standard industrial and commercial applications within the specified operating temperature range of -40°C to 85°C.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the MAX307EPI+? A: A valid substitute must match all electrical parameters including 8:1 multiplexer configuration, dual circuit topology, 100Ohm on-state resistance, and specified supply voltage ranges. The substitute must also be packaged in 28-DIP through-hole format with identical mechanical dimensions and maintain ROHS3 compliance.

Q: Can I use a different package variant of the MAX307? A: No. The MAX307EPI+ is specifically a 28-DIP through-hole package. Variants in different packages (such as surface-mount or smaller DIP configurations) are not direct substitutes due to mechanical incompatibility with the PCB layout and mounting requirements.

Q: Are there performance differences between equivalent MAX307EPI+ units? A: No. All MAX307EPI+ units from Analog Devices Inc./Maxim Integrated meet identical electrical specifications for on-state resistance, switch timing, charge injection, and crosstalk performance. Differences may exist only in manufacturing date codes or inventory source.

Q: What supply voltage configurations does the MAX307EPI+ support? A: The MAX307EPI+ supports both single supply operation (5V to 30V) and dual supply operation (±4.5V to ±20V), providing flexibility for various circuit topologies and power distribution schemes.

Q: Is the MAX307EPI+ suitable for high-frequency signal routing? A: The MAX307EPI+ is suitable for applications requiring switch times of 200ns (turn-on) and 150ns (turn-off) with crosstalk performance of -92dB at 100kHz. Application suitability depends on specific frequency and signal integrity requirements of the target circuit.

Q: What is the leakage current specification for the MAX307EPI+? A: The maximum off-state leakage current (IS(off)) is 500pA, ensuring minimal signal degradation when channels are in the off state.
