MAX384CPN+

Overview

The MAX384CPN+ is a dual 4-channel analog multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It operates on single supplies from +2.7V to +16.5V or dual supplies from ±3V to ±8V. The device features latchable digital inputs, low on-resistance of 100Ω max, and guaranteed channel matching within 4Ω. It offers low off-leakage current of less than 2.5nA at +85°C and charge injection of 10pC max. ESD protection exceeds 2000V per Method 3015.7. The component is housed in an 18-pin Plastic DIP package.

Feature Summary

• Dual 4-channel configuration with latchable digital inputs for simplified microprocessor interfacing
• Low on-resistance of 100Ω maximum with guaranteed matching between channels within 4Ω
• Compatible with TTL/CMOS logic levels and supports both single and bipolar supply operation
• High ESD protection exceeding 2000V per Method 3015.7

Applications

• Battery-operated systems
• Audio signal routing
• Low-voltage data-acquisition systems
• Sample-and-hold circuits
• Automatic test equipment

Procurement Notes

Verify the specific suffix 'CPN' corresponds to the 0°C to +70°C temperature range and 18-pin Plastic DIP package. Confirm RoHS compliance status as '+'. Check for obsolescence notices or PCNs affecting availability. Ensure pin compatibility requirements match DG428/DG429 standards if replacing legacy components.

Selection Notes

Select this part for applications requiring dual independent 4-channel switching with latched address inputs. It is suitable for low-voltage environments using single or dual power rails. Consider the 100Ω on-resistance and 4Ω matching tolerance for signal integrity requirements. Verify that the 18-pin DIP package fits the target PCB layout constraints.

Part Context

The MAX384 is part of the MAX382/MAX384 family of low-voltage CMOS multiplexers. It serves as a dual-channel version of the MAX382, which is an 8-channel single-ended mux. Both devices share similar electrical characteristics and are designed for pin-compatible replacement of industry-standard switches like the DG428/DG429.

Replacement Considerations

Pin-compatible replacements include DG428, DG429, DG528, DG529, MAX368, and MAX369. Verify voltage ranges and leakage specifications when substituting.
