MAX384CPN

Overview

The MAX384CPN is a dual 4-channel CMOS analog multiplexer with latchable digital inputs, housed in an 18-pin Plastic DIP package. It supports single-supply operation from +2.7V to +16.5V and dual supplies from ±3V to ±8V. The device features a maximum on-resistance of 100Ω with a guaranteed matching between channels of 4Ω max. Off-leakage current is less than 2.5nA at +85°C, and charge injection is guaranteed at 10pC max. It offers ESD protection exceeding 2000V per Method 3015.7 and operates within a temperature range of 0°C to +70°C.

Feature Summary

• Pin-compatible with industry-standard DG428/DG429, DG528/DG529, and MAX368/MAX369 devices.
• Features latchable digital inputs for simplified microprocessor bus interfacing without constant address holding.
• Provides low power consumption and TTL/CMOS-logic compatibility.

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 18-pin Plastic DIP package and the commercial temperature range (0°C to +70°C). Confirm that the component meets the required voltage specifications for your application, as it supports both single and dual supply configurations. Check for end-of-life status or obsolescence notices prior to finalizing procurement plans.

Selection Notes

Select this component when pin compatibility with legacy DG428/DG429 designs is required while utilizing modern low-voltage CMOS technology. It is suitable for applications needing latchable inputs to reduce microprocessor overhead. Ensure the analog signal range fits within the chosen supply voltage limits, and consider the 100Ω on-resistance flatness for precision signal switching requirements.

Part Context

The MAX384CPN belongs to the MAX382/MAX384 family of low-voltage multiplexers manufactured by Analog Devices Inc./Maxim Integrated. This series includes the single-ended 8-channel MAX382 and the dual 4-channel MAX384 variants. Both share identical logic interfaces and electrical characteristics, differing primarily in channel count and configuration.

Replacement Considerations

Public confirmed substitute part numbers include DG428, DG429, DG528, DG529, MAX368, and MAX369 due to direct pin compatibility.
