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.
Feature Summary
- On-board address and control latches reduce board space requirements
- Break-before-make switching prevents momentary shorting of input signals
- TTL and CMOS logic compatible digital inputs
- Microprocessor-bus compatible interface
Applications
- Data-acquisition systems
- Automatic test equipment
- Avionics and military systems
- Communication systems
- Microprocessor-controlled systems
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.
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.
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.
Replacement Considerations
Publicly confirmed substitutes include the ADG528 and industry-standard DG528 variants. These parts are pin and electrically compatible with the DG528 series.
