Overview
The DG528DJ+ is an 8-channel, single-ended CMOS 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, switching times of 1.5µs, and a power dissipation of 889mW in the 18-pin DIP package. It supports through-hole installation within an operating temperature range of -40°C to +85°C.
Feature Summary
- Monolithic CMOS design with integrated address and control latches
- Break-before-make switching mechanism to prevent signal shorting
- Compatible with TTL and CMOS logic levels
Applications
- Data-acquisition systems
- Automatic test equipment
- Microprocessor-controlled systems
Procurement Notes
Verify the specific suffix 'DJ+' against official manufacturer documentation to confirm the plastic DIP package and industrial temperature rating (-40°C to +85°C). Ensure compatibility with required voltage rails and logic interfaces before integration. Cross-reference part numbers with authorized distributors to confirm current availability status.
Selection Notes
Select this component for applications requiring latchable 8-channel analog switching with low power consumption. Verify that the 450Ω on-resistance meets system requirements. Confirm that the 18-pin DIP footprint fits the PCB layout constraints. Ensure the operating temperature range aligns with the environmental conditions of the final assembly.
Part Context
This component belongs to the DG528/DG529 series of 8-channel latchable multiplexers. The DG528 variant specifically handles single-ended signals, whereas the DG529 supports differential inputs. Both share identical pinouts and control logic, differing primarily in internal channel configuration for single-ended versus differential signal routing.
Replacement Considerations
The ADG528 is electrically and pin-compatible with the DG528 series. Verify that any substitute maintains the same latch functionality and on-resistance characteristics.
