MAX384CWN+

Overview

The MAX384CWN+ is a dual 4-channel 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 offers low on-resistance of 100 Ω max, matched within 4 Ω between channels, and low off-leakage current less than 2.5nA at +85°C. It provides ESD protection exceeding 2000V per Method 3015.7 and is compatible with TTL/CMOS logic. The component is housed in an 18-Wide SOIC package.

Feature Summary

• Dual 4-channel configuration with latchable digital inputs for simplified microprocessor interfacing
• Low power consumption under 300µW with guaranteed low charge injection
• Pin-compatible with industry-standard DG428/DG429 and MAX368/MAX369 devices

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 with lead-free compliance. Confirm availability status as the part may be discontinued or subject to limited supply constraints depending on the distributor. Ensure the ordering code matches the required pin count and package width specifications for PCB layout compatibility.

Selection Notes

Select this component when a dual independent 4-channel analog switch is required with latching functionality to reduce address line usage. It is suitable for applications needing low on-resistance matching and operation across wide single or dual supply voltages. Consider the 18-pin Wide SOIC package dimensions for board space constraints and verify thermal requirements against the specified operating temperature range.

Part Context

This part belongs to the MAX382/MAX384 family of low-voltage CMOS multiplexers. The MAX384 variant specifically provides two independent 4-channel switches, whereas the MAX382 offers a single 8-channel configuration. Both share identical electrical characteristics and pinouts, differing primarily in channel count and internal decoder structure.

Replacement Considerations

The MAX384CWN+ is pin-compatible with the DG428, DG429, DG528, DG529, MAX368, and MAX369. Verify that substitute parts meet the same voltage ranges and on-resistance specifications before implementation.
