MAX384CWN

Overview

The MAX384CWN is a dual 4-channel analog multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It features latchable digital inputs and operates on single supplies from +2.7V to +16.5V or dual supplies from ±3V to ±8V. The device provides low on-resistance of 100Ω max, matched within 4Ω between channels, and off leakage less than 2.5nA at +85°C. It is housed in an 18-pin Wide SOIC package with an operating temperature range of 0°C to +70°C.

Feature Summary

• Dual 4-channel configuration with latchable digital inputs for simplified microprocessor interfacing
• Low on-resistance of 100Ω maximum with guaranteed matching within 4Ω between channels
• Compatible with TTL/CMOS logic levels and offers low power consumption under 300µW
• 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 'C' indicates the commercial temperature range (0°C to +70°C) and 'WN' denotes the 18-pin Wide SOIC package. Confirm RoHS compliance status as the component may be obsolete. Ensure supply voltage requirements match the application's single or dual rail constraints before procurement.

Selection Notes

Select this component when a dual independent 4-channel mux is required with latchable address inputs to reduce bus contention. It serves as a pin-compatible replacement for industry-standard DG428/DG429 devices. Consider its low on-resistance and low charge injection characteristics for precision analog signal switching applications.

Part Context

This part belongs to the MAX382/MAX384 family of low-voltage CMOS multiplexers. The MAX384 specifically provides two independent 4-channel switches, whereas the MAX382 offers a single 8-channel switch. Both share similar electrical characteristics and packaging options, designed for low-power analog signal routing.

Replacement Considerations

Pin-compatible alternatives include DG428, DG429, DG528, DG529, MAX368, and MAX369. Verify that substitute parts meet the specific latchable input requirement and voltage range specifications of the original design.
