DG506ACJ Equivalent & Substitute Parts
Part Overview
The DG506ACJ is a 16:1 analog multiplexer/demultiplexer integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. This interface component features a single circuit configuration with 450Ohm on-state resistance and operates across a dual supply voltage range of ±4.5V to ±18V. The device is packaged in a 28-pin DIP format suitable for through-hole mounting applications.
The DG506ACJ is classified as obsolete, which necessitates identification of equivalent substitute components for ongoing design support and procurement. Active alternatives with identical electrical and mechanical specifications are available to ensure design continuity.

Substitute Part Grouping Explanation
Substitution of the DG506ACJ is determined by strict equivalence across the following critical parameters:
- Multiplexer configuration: 16:1 topology
- Circuit count: Single circuit
- On-state resistance: 450Ohm maximum
- Supply voltage range: ±4.5V to ±18V dual supply
- Switching performance: 1µs rise time, 400ns fall time maximum
- Package format: 28-pin DIP through-hole
- Leakage current specification: 5nA maximum
The DG506ACJ+ qualifies as a direct substitute based on complete electrical and mechanical parameter alignment. The primary distinction is product status: the DG506ACJ is obsolete, while the DG506ACJ+ is active production, and RoHS compliance status differs between the two variants.
