MAX384CWN+T

Overview

The MAX384CWN+T is a dual 4-channel analog multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It operates with 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 leakage current and charge injection, ensuring signal integrity in data-acquisition systems.

Feature Summary

• Dual 4-channel configuration with latchable digital inputs for simplified microprocessor interfacing
• Low on-resistance with high matching accuracy between channels
• Compatible with TTL and CMOS logic families
• Supports both single and bipolar power supply configurations

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 'W' denotes the Wide SOIC package. Confirm RoHS compliance status through official manufacturer documentation before procurement. Ensure ordering aligns with the exact pinout and electrical specifications required for the target application design.

Selection Notes

Select this component when a dual 4-channel multiplexer with latching capability is required. It serves as a pin-compatible replacement for industry-standard DG428/DG429 devices. Consider its low power consumption and wide supply voltage range for applications requiring flexibility in power architecture and low standby current.

Part Context

This part belongs to the MAX382/MAX384 family of low-voltage CMOS multiplexers. The MAX384 specifically provides two independent 4-channel switches. It is designed for general-purpose analog switching applications where low distortion and high isolation are necessary. The family supports various package options including DIP and SOIC.

Replacement Considerations

Pin-compatible substitutes include DG428, DG429, DG528, DG529, MAX368, and MAX369. Verify that the alternative device meets the specific on-resistance and leakage requirements of the original design.
