MAX382EWN

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX382EWN 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. ESD protection exceeds 2000V per Method 3015.7. It is housed in an 18-Wide SOIC package and supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' indicates the extended industrial temperature range (-40°C to +85°C). Confirm the 'W' suffix corresponds to the 18-pin Wide SOIC package. Ensure compatibility with existing board layouts designed for pin-compatible alternatives like the DG428. Check for RoHS compliance status if required by project specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a single 8-channel analog switch with latching capability is required. It is suitable for applications needing low power consumption and high ESD protection. Consider the on-resistance flatness and leakage characteristics relative to the specific analog signal range and supply voltage used in the design.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX382EWN belongs to the MAX382/MAX384 family of low-voltage multiplexers manufactured by Maxim Integrated (now Analog Devices Inc.). This series is designed for general-purpose analog signal switching in portable and battery-powered devices. The 'E' grade denotes the extended temperature range variant, while 'W' specifies the surface-mount package type.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible substitutes include the DG428, DG429, DG528, DG529, MAX368, and MAX369. Verify that the alternative part meets the required temperature range and electrical specifications before substitution.
