DG528DJ+

Analog Switches, Multiplexers, Demultiplexers 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.

Analog Switches, Multiplexers, Demultiplexers 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.

Analog Switches, Multiplexers, Demultiplexers 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.

Analog Switches, Multiplexers, Demultiplexers 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.

Analog Switches, Multiplexers, Demultiplexers 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.
