MAX382CWN

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX382CWN is a low-voltage CMOS 1-of-8 multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply of +2.7V to +16.5V or dual supplies of ±3V to ±8V. The device features a maximum on-resistance of 100Ω with channel matching within 4Ω. Electrical specifications include a maximum charge injection of 2pC, off-leakage current of 200pA, and crosstalk of -92dB at 100kHz. Switching times are rated at 150ns for both turn-on and turn-off. It is housed in an 18-SOIC package and supports an operating temperature range of 0°C to 70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or the manufacturer directly. Confirm RoHS compliance status as the original MAX382CWN may not meet current environmental standards compared to the MAX382CWN+ variant. Ensure the specific ordering suffix matches the required temperature range and packaging configuration before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when pin compatibility with legacy DG428/DG429 designs is required. Choose the MAX382CWN for applications needing a single 8-channel mux with latchable inputs. Verify that the 100Ω on-resistance meets system requirements. Consider the MAX382CWN+ if lead-free manufacturing processes are mandatory for the production line.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX382CWN belongs to the MAX382/MAX384 family of low-voltage multiplexers. It serves as the single 8-channel version of this series, designed for general-purpose analog signal switching. The device integrates latches to simplify control logic, distinguishing it from non-latching counterparts like the MAX398/MAX399.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX382CWN+ is a direct replacement offering identical functionality with lead-free construction. Other compatible parts include the DG428 and DG429 due to pin compatibility.
