DG528DJ

Analog Switches, Multiplexers, Demultiplexers Overview

The DG528DJ+ is an 8-channel, single-ended CMOS analog multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It features on-board address and control latches to simplify microprocessor-based designs. The device operates with dual supplies ranging from ±4.5V to ±20V or a single supply from +5V to +30V. Key electrical parameters include a maximum on-resistance of 450Ω, a maximum switching time of 1.5µs, and a maximum power dissipation of 889mW in the 18-pin Plastic DIP package. It supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'DJ' corresponds to the -40°C to +85°C temperature range and 18-pin Plastic DIP package configuration. Confirm RoHS compliance status for the '+' designation. Ensure the ordering part number matches the exact manufacturer specifications provided in the official datasheet before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when latchable 8-channel multiplexing is required for microprocessor interfaces. Verify that the 450Ω maximum on-resistance meets signal integrity requirements. Ensure the supply voltage range aligns with the system's available power rails. Consider the 18-pin DIP footprint for through-hole mounting constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG528/DG529 series of monolithic CMOS multiplexers. The DG528 variant specifically provides single-ended 1-of-8 switching, whereas the DG529 offers differential 2-of-8 switching. Both share identical pinouts and control logic structures.
