MAX382CPN

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX382CPN is a low-voltage, CMOS 1-of-8 multiplexer featuring latchable digital inputs. It operates from a +2.7V to +16.5V single supply or ±3V to ±8V dual supplies. The device offers a maximum on-resistance of 100Ω with channel matching within 4Ω. Key electrical parameters include off-leakage less than 2.5nA at +85°C and guaranteed charge injection of 10pC max. It provides over 2000V ESD protection per Method 3015.7 and is pin-compatible with industry-standard DG428/DG429 devices.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Pin-compatible with industry-standard DG428/DG429, DG528/DG529, MAX368/MAX369
• Single-supply operation (+2.7V to +16.5V) and bipolar supply operation (±3V to ±8V)
• Low power consumption (<300µW) and TTL/CMOS-logic compatible
• Guaranteed low charge injection (10pC max) and low leakage (2.5nA at +85°C)

Analog Switches, Multiplexers, Demultiplexers Applications

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CPN' corresponds to the 18-pin Plastic DIP package and the commercial temperature range of 0°C to +70°C. Confirm that the component meets RoHS compliance standards as indicated by the '+' designation in the ordering information. Ensure compatibility with existing PCB footprints for 18-PDIP packages before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX382CPN when an 8-channel multiplexer with latchable inputs is required for low-voltage applications. This part is suitable for designs needing pin compatibility with DG428/DG429. Consider the 100Ω max on-resistance and 4Ω matching for signal integrity requirements. Verify that the operating voltage range of +2.7V to +16.5V fits the system power constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX382 is part of Maxim Integrated's low-voltage multiplexer family, designed for general-purpose analog switching. It complements the dual 4-channel MAX384 variant. The CPN suffix denotes the commercial grade temperature range and plastic DIP packaging, distinguishing it from extended temperature or wide SOIC variants within the same functional series.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include DG428, DG429, DG528, DG529, MAX368, and MAX369 due to pin compatibility. Verify that replacement parts meet the specific on-resistance and leakage requirements of the original design.
