Product details
Overview
DG529EWN from Maxim Integrated is a differential, 2-of-8 CMOS analog multiplexer with on-board address latches, break-before-make switching, and dual-supply (±4.5V to ±20V) or single-supply (+5V to +30V) operation. It supports TTL/CMOS logic inputs, features rDS(ON) < 400Ω, and is used in precision data-acquisition systems requiring channel isolation and microprocessor-bus compatibility.
For engineers reviewing the DG529EWN datasheet, DG529EWN pinout, DG529EWN application, or DG529EWN equivalent, key selection criteria include its differential 2-channel switching architecture, latchable address interface, ±15V analog signal range, 0.2µs break-before-make interval, and Wide SO-18 package suitability for high-density industrial PCB layouts.
Technical Context
The DG529EWN implements a dual-channel differential multiplexing architecture using parallel N- and P-MOSFET switch pairs per channel, enabling simultaneous routing of complementary analog signals (e.g., IN1A/IN1B). Its internal decode logic accepts A1/A0 address inputs and uses WR/RS strobes to control latching and reset behavior.
It operates in three modes: transparent (WR low, RS high), latched (WR high), and reset (RS low), with EN enabling global channel disable. Digital thresholds remain stable at ~1.6V over temperature and supply variations, ensuring reliable interfacing with standard TTL logic even at ±5V supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V - Supports full-rail switching of bipolar signals without clipping when V+ = +15V, V− = −15V |
| rDS(ON) | < 400Ω - Low on-resistance ensures minimal signal attenuation and gain error in precision measurement paths |
| Break-Before-Make Interval | 0.2µs - Prevents momentary shorting between differential input pairs during channel transitions |
| Charge Injection | 4pC - Low charge injection minimizes voltage glitches at output nodes during switching |
| Enable Turn-On Time | 1.0–1.5µs - Fast enable response enables tight timing control in synchronized acquisition systems |
| Off Isolation | 68dB - High channel-to-channel isolation preserves signal integrity in multi-channel differential sensing |
| Supply Range | ±4.5V to ±20V or +5V to +30V - Flexible power architecture supports both bipolar instrumentation and unipolar industrial systems |
Pinout & Package
DG529EWN is housed in an 18-pin Wide SO (Small Outline) package, 7.62mm × 10.50mm body size, with 1.27mm lead pitch and gull-wing leads compatible with standard surface-mount reflow processes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG529FBRUZ | Higher rDS(ON) (500Ω typ), wider temp range (−55°C to +125°C), same Wide SO-18 footprint | Better suited for extended-temperature avionics; higher on-resistance increases gain error in precision DC measurements | Select ADG529FBRUZ only when extended temperature operation outweighs on-resistance sensitivity in the signal chain |
| DG529DK | CERDIP ceramic package, same electrical specs, −40°C to +85°C rating, hermetic sealing | Required for high-reliability military/aerospace deployments where moisture resistance and long-term stability are critical | Choose DG529DK when board-level hermeticity or MIL-STD-883 qualification is mandated, accepting higher cost and manual assembly complexity |
Compared with DG529EWN, ADG529FBRUZ trades lower on-resistance for broader temperature capability, while DG529DK provides identical performance in a hermetic ceramic package-making DG529EWN the optimal balance of cost, performance, and manufacturability for commercial and industrial surface-mount designs.

FAQ
What is the operating temperature range of the DG529EWN?
The DG529EWN is rated for operation from −40°C to +85°C. This extended industrial temperature range ensures reliable performance in demanding environments such as factory automation controllers, outdoor test instrumentation, and vehicle-mounted data loggers-without derating or thermal management overhead beyond standard PCB layout practices.
How does the DG529EWN differ from the DG528EWN?
The DG529EWN is a differential 2-of-8 multiplexer, routing two complementary analog signals per selected channel pair (e.g., IN1A/IN1B → DA/DB), whereas the DG528EWN is a single-ended 1-of-8 device. The DG529EWN's dual-output architecture preserves common-mode rejection, making it essential for noise-immune sensor interfaces where the DG528EWN would require external differential amplification.
Can the DG529EWN operate from a single +12V supply?
Yes, the DG529EWN supports single-supply operation from +5V to +30V. When using +12V, connect V− to GND and limit analog input signals to 0V–12V. Note that rDS(ON) increases slightly versus dual-supply operation, but remains below 400Ω-ensuring adequate performance for most industrial signal-routing applications.
What is the function of the RS pin on the DG529EWN?
The RS (Reset) pin on the DG529EWN is an active-low control that forces all internal latches to clear and disables all eight differential switch paths simultaneously. When RS is pulled low, the device enters a known state with no channels conducting-critical for safe power-up sequencing, fault recovery, and system-level reset coordination in safety-critical designs.
Is the DG529EWN pin-compatible with the ADG529 series?
Yes, the DG529EWN is pin and electrically compatible with the ADG529 family (e.g., ADG529FBRUZ) per Maxim's datasheet. Both share identical Wide SO-18 pinout, logic thresholds, timing parameters, and functional behavior-enabling drop-in substitution in existing designs without PCB or firmware changes, provided supply and temperature requirements align.
