Product details
Overview
DG529CWN+ 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+ datasheet, DG529CWN+ pinout, DG529CWN+ application, or DG529CWN+ equivalent, key selection criteria include its differential input architecture, latch-controlled channel selection via WR/RS strobes, guaranteed break-before-make timing (tOPEN = 0.2µs), and compatibility with legacy DG529 and ADG529 families in wide-SO-18 packaging.
Technical Context
The DG529CWN+ implements a differential 2-of-8 switching matrix using parallel N- and P-channel MOSFET structures per switch path, with integrated level-shifted translators for A0/A1/EN/WR/RS inputs and a 4-bit-wide latch driving a decode section. Its internal substrate is tied to V+, enabling robust operation across wide supply ranges.
It supports transparent mode (WR low, RS high), latched mode (WR high), and reset mode (RS low), with timing parameters including tON(EN, WR) = 1.0–1.5µs, tOFF(EN, RS) = 0.4–1.0µs, and tTRANS = 0.4–1.0µs - all specified at V+ = +15V, V− = −15V, TA = +25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±10V - supports bipolar signal routing without level-shifting circuitry |
| rDS(ON) | <400Ω typical - ensures minimal voltage drop and gain error in precision signal paths |
| Break-Before-Make Interval | 0.2µs minimum - prevents momentary shorting between differential input pairs during switching |
| Supply Range | ±4.5V to ±20V dual or +5V to +30V single - enables flexible power architecture in mixed-signal systems |
| Logic Compatibility | TTL and CMOS - interfaces directly with 5V µP buses without level translation |
| Charge Injection | 4pC typical - limits transient voltage error (ΔVO = Q/CL) in sample-and-hold or ADC front-end use |
| Off Isolation | 68dB at 500kHz - suppresses crosstalk between inactive and active differential channels |
Pinout & Package
DG529CWN+ is housed in an 18-pin Wide SO (Small Outline) package, 0.300-inch body width, with gull-wing leads and JEDEC MS-013AC compliance. Pin 1 is marked by a beveled corner or dot; pin 10 is GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (RS) | Reset Strobe Input | Active-low signal that clears all latches and disables all switches - critical for system initialization and fault recovery |
| 2 (A1) | Address Bit 1 Input | Binary address line selecting one of four differential channel pairs (S1A/S1B through S4A/S4B) |
| 3 (GND) | Ground Reference | Common return for digital logic and analog signal reference - must be low-impedance for noise immunity |
| 4 (V+) | Positive Supply Rail | Accepts +5V to +30V (single) or up to +20V (dual); powers analog switches and internal logic |
| 5 (S1B) | Differential Channel 1, Negative Input | Paired with S1A to form fully differential input path - enables common-mode rejection in noisy environments |
| 6 (S2B) | Differential Channel 2, Negative Input | Second negative leg of 2-of-8 differential pair - maintains matched parasitics with corresponding SxA pins |
| 7 (S3B) | Differential Channel 3, Negative Input | Third negative input in differential set - routed symmetrically to minimize skew vs. SxA counterparts |
| 8 (S4B) | Differential Channel 4, Negative Input | Final negative input of differential group - completes 4× differential channel support (8 total terminals) |
| 9 (DB) | Differential Output, Negative | Common negative output node for selected differential pair - requires matched termination to DA |
| 10 (WR) | Write Strobe Input | Edge-triggered latch control: falling edge captures A0/A1 state to hold channel selection indefinitely |
| 11 (A0) | Address Bit 0 Input | LSB of 2-bit binary address - combined with A1 to select S1–S4 differential pairs |
| 12 (EN) | Enable Input | Active-high global enable: EN = 0 disables all switches regardless of address or WR state |
| 13 (V−) | Negative Supply Rail | Accepts −4.5V to −20V (dual) or 0V (single supply); ties substrate to V+ for latch stability |
| 14 (S1A) | Differential Channel 1, Positive Input | Positive leg of first differential pair - matched to S1B for balanced signal integrity |
| 15 (S2A) | Differential Channel 2, Positive Input | Positive leg of second differential pair - identical layout and drive strength to S1A |
| 16 (S3A) | Differential Channel 3, Positive Input | Positive leg of third differential pair - maintains consistent rDS(ON) and charge injection vs. others |
| 17 (S4A) | Differential Channel 4, Positive Input | Positive leg of fourth differential pair - completes full 2-of-8 differential switching capability |
| 18 (DA) | Differential Output, Positive | Common positive output node - must be terminated identically to DB to preserve common-mode rejection |
Key Features
| Feature | Design Value |
|---|---|
| On-board address latches | Eliminates need for external address hold registers - reduces PCB area and timing complexity in µP-controlled systems |
| Break-before-make switching | Guarantees 0.2µs minimum open interval - prevents destructive current flow when routing high-precision differential signals |
| Dual- or single-supply operation | Supports ±5V to ±20V or +5V to +30V rails - simplifies power design in mixed-voltage industrial and avionics platforms |

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 max), wider temp range (−40°C to +125°C), no RS pin - uses EN-only reset | Better suited for extended-temperature industrial control where latch persistence is less critical than thermal robustness | Select ADG529FBRUZ when operating beyond +70°C or when simplified reset logic (EN-only) suffices |
| DG529DJ | Same die, plastic DIP-18 package, −40°C to +85°C rating, identical pinout and electrical specs | Preferred for prototyping, through-hole assembly, or legacy board reuse where SOIC footprint is unavailable | Choose DG529DJ for manual soldering, breadboarding, or backward compatibility with existing DIP-based designs |
Compared with DG529CWN+, ADG529FBRUZ trades lower leakage and higher temperature tolerance for reduced switching speed and missing RS functionality, while DG529DJ offers identical performance in a through-hole package - making DG529CWN+ optimal for surface-mount production targeting commercial-temperature, high-density PCBs.

FAQ
What is the maximum analog signal voltage range supported by the DG529CWN+?
The DG529CWN+ supports an analog signal range of ±10V when operated with dual supplies (e.g., ±15V). This range is defined by the voltage difference between V+ and V−, and remains valid across its full specified supply range of ±4.5V to ±20V. The DG529CWN+ does not support signals exceeding these rail-to-rail limits without external clamping or level-shifting circuitry.
Does the DG529CWN+ require external pull-up resistors on its digital control lines?
No, the DG529CWN+ does not require external pull-up resistors on A0, A1, EN, WR, or RS inputs. Its digital inputs exhibit nanoamp-level leakage (<1µA max) and are internally compatible with TTL and CMOS logic thresholds (VAL ≤0.8V, VAH ≥2.4V). Pull-ups are only needed if the driving source cannot meet these voltage levels or lacks sufficient drive strength.
Can the DG529CWN+ operate from a single +12V supply?
Yes, the DG529CWN+ can operate from a single +12V supply. In this configuration, connect V− to ground, and ensure digital inputs are referenced to the same ground. Analog signals must remain within 0V to +12V. Performance parameters such as rDS(ON) and switching time remain within specification, though tTRANS increases slightly compared to ±15V operation.
What is the function of the RS (Reset) pin on the DG529CWN+?
The RS pin on the DG529CWN+ is an active-low control that clears all internal address latches and disables all analog switches, forcing the device into a known-off state. When RS is pulled low, no channel conducts regardless of A0/A1 state or WR level. This provides deterministic fault recovery and safe power-up sequencing for the DG529CWN+.
Is the DG529CWN+ pin-compatible with the ADG529 series?
Yes, the DG529CWN+ is pin and electrically compatible with the ADG529 family in the 18-pin Wide SO package. Both share identical pin assignments, supply requirements, logic thresholds, and switching characteristics. However, ADG529 variants may differ in temperature range, rDS(ON) max, or leakage specs - always verify datasheet alignment before substitution.
