Product details
Overview
DG508ACJZ from Intersil is a CMOS monolithic 8-channel analog multiplexer with TTL/CMOS-compatible address and enable inputs, ±15V analog signal range, 270Ω typical ON-resistance, and break-before-make switching. It operates from 0°C to +70°C in a 16-lead PDIP package and is used in data acquisition systems for routing sensor signals to ADCs.
For engineers reviewing the DG508ACJZ datasheet, DG508ACJZ pinout, DG508ACJZ application, or DG508ACJZ equivalent, key selection criteria include its 44V max supply rating, 68dB OFF isolation at 500kHz, 4pC charge injection, 0.6μs transition time, and Pb-free (RoHS-compliant) 16-lead PDIP packaging.
Technical Context
The DG508ACJZ implements a 3-line binary decoder driving eight transmission gates, enabling one of eight bidirectional analog channels based on A0–A2 inputs when EN is high. Its switch architecture supports rail-to-rail analog signals up to ±15V with symmetrical rDS(ON) performance across positive and negative voltages.
Break-before-make timing ensures no channel overlap during address transitions, while internal level-shifting circuitry allows TTL/CMOS logic compatibility across the full operating temperature range. The device draws only 1.3mA typical positive supply current in enabled mode and features high latch-up immunity per design.

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DG408DN | Pin-compatible 8-channel CMOS mux; lower 100Ω rDS(ON), but rated only to ±15V supply and 0°C to +70°C | Superior ON-resistance for low-gain error, but lacks DG508ACJZ's 44V max supply rating and higher OFF isolation (72dB) | Select DG408DN where lowest rDS(ON) is critical and supply voltage stays within ±15V; retain DG508ACJZ for wider supply flexibility and higher isolation. |
| ADG508AKRZ | Functionally equivalent 8:1 mux; 180Ω rDS(ON), 70dB OFF isolation, but specified for −40°C to +85°C and uses different PDIP footprint (E16.1) | Broadened temperature range and improved specs, but not pinout-compatible due to differing pin 1 location and thermal pad absence | Choose ADG508AKRZ for extended temp operation and tighter specs; use DG508ACJZ where legacy PDIP layout and RoHS-compliant matte tin finish are required. |
Compared with DG408DN and ADG508AKRZ, the DG508ACJZ offers unique value in 44V supply tolerance, Pb-free RoHS compliance with SnPb reflow compatibility, and proven 0°C to +70°C stability in legacy industrial designs-making it optimal for drop-in replacement in existing PDIP-based systems where supply headroom and process compatibility are decisive.

FAQ
What is the maximum supply voltage rating for the DG508ACJZ?
The DG508ACJZ has a maximum V+ to V− rating of 44V, allowing operation with supply combinations such as ±20V, +36V/–8V, or +40V/–4V. This exceeds standard ±15V rails and provides design margin against transient overvoltage events in industrial power domains. The DG508ACJZ maintains specified performance across its full 0°C to +70°C operating range under these conditions.
Does the DG508ACJZ support bidirectional analog signal flow?
Yes, the DG508ACJZ supports fully bidirectional analog conduction: any selected channel (S1–S8) conducts current equally well from source to drain or drain to source. This is inherent to its CMOS transmission gate architecture and enables flexible use as either a multiplexer (multiple inputs → one output) or demultiplexer (one input → multiple outputs), as confirmed in the functional diagram and truth table of the DG508ACJZ datasheet.
What is the typical ON-resistance of the DG508ACJZ and how does it vary?
The DG508ACJZ exhibits 270Ω typical rDS(ON) at ±15V supplies and 25°C, with matching between channels within ±6%. Variation over temperature is characterized in Figure 6: rDS(ON) rises to ~350Ω at 125°C but remains stable below 300Ω across the DG508ACJZ's rated 0°C to +70°C range. This consistency ensures predictable gain and offset behavior in precision analog signal chains.
Is the DG508ACJZ pinout compatible with industry-standard 8-channel multiplexers?
Yes, the DG508ACJZ is explicitly stated in its datasheet to be pinout compatible with industry-standard devices, including the original DG508 series and functionally similar parts like the CD4051B. Its 16-pin PDIP layout (E16.3) matches mechanical and electrical pin assignments for direct PCB replacement in legacy designs without layout modification.
What does "Pb-free" mean for the DG508ACJZ and is it compatible with SnPb soldering?
The DG508ACJZ uses 100% matte tin plating and Pb-free molding compounds, meeting RoHS Directive 2011/65/EU. Per Intersil's note, its Pb-free construction is fully compatible with both SnPb and Pb-free reflow processes, certified to IPC/JEDEC J-STD-020C peak temperatures. No special assembly changes are needed when migrating from SnPb to Pb-free solder using the DG508ACJZ.
