Product details
Overview
DG529CWN+T from Maxim Integrated is a differential 2-of-8 CMOS analog multiplexer with on-board address latches, break-before-make switching, ±4.5V to ±20V dual-supply operation (or +5V to +30V single supply), rDS(ON) < 400Ω typical, and TTL/CMOS-compatible digital inputs - used in precision data-acquisition systems requiring channel isolation and microprocessor-bus interfacing.
For engineers reviewing the DG529CWN+T datasheet, DG529CWN+T pinout, DG529CWN+T application, or DG529CWN+T equivalent, key selection criteria include its differential input architecture, latch-controlled channel selection, guaranteed break-before-make timing (tOPEN = 0.2 µs), and compatibility with legacy DG529/ADG529 designs in wide-SO-18 packaging.
Technical Context
The DG529CWN+T implements a differential 2-of-8 switching matrix using parallel N- and P-channel MOSFET structures per channel, with integrated level-shifted translators for A0/A1/EN/WR/RS inputs and a 4-bit-wide latch enabling transparent or latched operation modes. Its internal decode logic supports three distinct functional states: transparent (WR low, RS high), latched (WR high), and reset (RS low).
It operates across ±4.5V to ±20V dual supplies or +5V to +30V single supply, with analog signal range spanning –15V to +15V under ±15V conditions, and maintains break-before-make interval (tOPEN = 0.2 µs) and charge injection (Q = 4 pC) independent of supply voltage within rated ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V under ±15V supplies - supports full-rail bipolar signal routing without clipping |
| rDS(ON) | <400Ω typical - ensures low insertion loss and minimal gain error in precision signal paths |
| Break-Before-Make Interval | 0.2 µs - prevents momentary shorting between differential input pairs during channel transitions |
| Charge Injection | 4 pC - limits voltage glitch at output due to switching transients in sampled-data systems |
| Logic Input Compatibility | TTL and CMOS - interfaces directly with 5V microcontrollers and FPGAs without level-shifting |
| Supply Range | ±4.5V to ±20V dual or +5V to +30V single - enables flexible power architecture in mixed-signal industrial systems |
| Enable Turn-On Time | 1.0–1.5 µs - defines minimum channel activation latency in time-critical acquisition sequences |
Pinout & Package
Package: 18-pin Wide SO (SOIC-Wide), 0.300-inch body width, RoHS-compliant, surface-mountable with standard reflow profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (RS) | Reset Strobe Input | Active-low signal that clears all latches and disables all channels simultaneously |
| 2 (A1) | Address Bit 1 | Binary address input selecting one of four differential channel pairs (S1A/S1B through S4A/S4B) |
| 3 (GND) | Analog/Digital Ground | Common reference for analog signals and digital control logic; must be low-impedance |
| 4 (V+) | Positive Supply Rail | Connects to +4.5V to +20V (dual) or +5V to +30V (single); powers analog switch core |
| 5 (S1B) | Differential Channel 1, Negative Input | Paired with S1A to form first differential input path; routed to DA/DB outputs when selected |
| 6 (S2B) | Differential Channel 2, Negative Input | Second differential pair; shares same enable and address logic as S1B–S4B |
| 7 (S3B) | Differential Channel 3, Negative Input | Third differential pair; supports simultaneous routing of two independent analog signals |
| 8 (S4B) | Differential Channel 4, Negative Input | Fourth differential pair; completes 2-of-8 selection matrix for balanced signal handling |
| 9 (DB) | Differential Output, Negative | Negative output terminal for selected differential channel pair; complements DA |
| 10 (WR) | Write Strobe Input | Active-low latch strobe: captures current A0/A1 state to hold channel selection indefinitely |
| 11 (A0) | Address Bit 0 | LSB of 2-bit binary address; combined with A1 determines active differential channel pair |
| 12 (EN) | Enable Input | Active-high global enable: disables all switches when low, overriding address and latch state |
| 13 (V-) | Negative Supply Rail | Connects to –4.5V to –20V (dual); required for negative analog signal support |
| 14 (S1A) | Differential Channel 1, Positive Input | Positive leg of first differential pair; routed to DA when S1A/S1B selected |
| 15 (S2A) | Differential Channel 2, Positive Input | Positive leg of second differential pair; enables true differential multiplexing capability |
| 16 (S3A) | Differential Channel 3, Positive Input | Positive leg of third differential pair; critical for noise-rejecting sensor interface designs |
| 17 (S4A) | Differential Channel 4, Positive Input | Positive leg of fourth differential pair; completes full 4× differential channel set |
| 18 (DA) | Differential Output, Positive | Positive output terminal for selected differential channel pair; paired with DB for balanced output |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG529BRZ | Pin-compatible 18-lead SOIC package; identical pinout and logic behavior; rDS(ON) = 450Ω max (vs. 400Ω typ for DG529CWN+T) | Same differential 2-of-8 function; slightly higher on-resistance increases gain error in precision gain stages | Select ADG529BRZ when sourcing from Analog Devices' qualified supply chain or for dual-sourcing flexibility |
| MAX4617ESA+ | Single-supply only (+2.7V to +12V); 8-channel single-ended (not differential); no on-board latches; smaller 8-pin SO package | Lacks differential routing and latch capability - suitable only for low-voltage, non-critical signal routing where space is constrained | Choose MAX4617ESA+ only for cost-sensitive, single-ended applications below 12V with no requirement for break-before-make or µP bus interfacing |
Compared with DG529CWN+T, ADG529BRZ offers identical functionality and pinout but trades 50Ω higher rDS(ON) for broader temperature qualification (–40°C to +85°C vs. 0°C to +70°C), while MAX4617ESA+ sacrifices differential operation, latching, and supply flexibility to achieve ultra-compact size and lower cost in non-precision roles.

FAQ
What is the operating temperature range for the DG529CWN+T?
The DG529CWN+T is specified for commercial-grade operation from 0°C to +70°C. This range is confirmed in the Ordering Information table, where "DG529C" suffix denotes the 0°C to +70°C grade. It is not rated for extended industrial (–40°C to +85°C) or military (–55°C to +125°C) temperatures unless marked with 'D', 'E', or 'A' suffixes.
Does the DG529CWN+T support single-supply operation?
Yes, the DG529CWN+T supports single-supply operation from +5V to +30V. When using a single supply, V– must be connected to ground, and the analog input range becomes 0V to V+. For example, with +15V supply, it switches signals from 0V to +15V. The device retains break-before-make timing and logic compatibility under single-supply conditions.
How does the WR (Write) pin function in the DG529CWN+T?
The WR pin is an active-low write strobe that latches the current state of A0 and A1 address inputs. When WR transitions from low to high, the addressed differential channel pair is held indefinitely until WR goes low again or RS is asserted. In transparent mode (WR low), the DG529CWN+T behaves like a non-latching multiplexer, passing through address changes in real time.
Is the DG529CWN+T pin-compatible with the ADG529 series?
Yes, the DG529CWN+T is explicitly stated in the datasheet to be pin and electrically compatible with the ADG529. Both devices share identical 18-pin Wide SO pinout, logic thresholds, timing parameters, and functional behavior - enabling direct substitution in existing ADG529-based designs without PCB or firmware changes.
What is the maximum analog signal voltage the DG529CWN+T can handle?
The DG529CWN+T supports analog signals from V– to V+, with absolute maximum ratings of ±44V on V+ and ±25V on GND referenced to V–. Under standard ±15V supplies, the usable analog range is –15V to +15V. Exceeding V+ or falling below V– risks permanent damage; signals must remain within the supply rails for reliable operation.
