Product details
Overview
DG528EWN+T from Maxim Integrated is a monolithic, single-ended 1-of-8 CMOS analog multiplexer with on-board address latches, break-before-make switching, ±4.5V to ±20V dual-supply or +5V to +30V single-supply operation, and TTL/CMOS-compatible digital inputs - designed for microprocessor-controlled data-acquisition systems requiring channel selection stability without continuous bus addressing.
For engineers reviewing the DG528EWN+T datasheet, DG528EWN+T pinout, DG528EWN+T application, or DG528EWN+T equivalent, key selection criteria include latchable address control, rDS(ON) < 400Ω at ±15V, -40°C to +85°C temperature range, 18-pin wide SOIC package, and compatibility with industry-standard DG528/DG529 logic timing and pinout.
Technical Context
The DG528EWN+T integrates parallel N- and P-channel MOSFET switch pairs per channel, controlled by a decoded BCD address (A2/A1/A0) routed through internal level shifters and latches. Its write (WR) and reset (RS) strobes enable µP-bus interfacing, allowing transparent mode (WR low) or latched channel hold (WR high), with RS forcing all switches off regardless of address state.
It supports asymmetric supplies (e.g., +15V/–5V), maintains analog signal range from V– to V+, and features digital input thresholds (~1.6V) stable across supply voltages and temperature (–3mV/°C), ensuring reliable TTL-level compatibility even at ±5V supplies without external level translation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±10V - supports bipolar signal routing without clipping when V+ = +15V, V– = –15V |
| rDS(ON) | < 400Ω (typ. 270Ω) - ensures minimal voltage drop and power loss in precision analog paths |
| Break-Before-Make Interval | 0.2µs - prevents momentary shorting between input channels during switching |
| Enable Turn-On Time | 1.0–1.5µs - enables fast channel activation under program control via EN pin |
| Charge Injection | 4pC - limits voltage glitch on switched nodes, critical for sample-and-hold integrity |
| Supply Range | ±4.5V to ±20V dual or +5V to +30V single - accommodates industrial, avionics, and test equipment rails |
| Operating Temperature | –40°C to +85°C - qualified for extended industrial and embedded environments |
Pinout & Package
Package: 18-pin Wide SOIC (SOIC-W), 0.300-inch body width, JEDEC MS-013 compliant, 1.27mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (RS) | Reset Strobe Input | Active-low signal that clears all latches and forces all channels OFF, independent of address |
| 2 (A1) | Address Bit 1 Input | BCD address line determining channel selection with A0 and A2; TTL/CMOS compatible |
| 3 (GND) | Analog/Digital Ground | Common reference for analog signals and digital logic; 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 |
| 5–12 (S1–S8) | Analog Switch Inputs | Eight single-ended analog input terminals; each connects to output D when selected |
| 13 (D) | Common Analog Output | Single-ended output node shared by all eight channels; routed to selected Sx input |
| 14 (WR) | Write Strobe Input | Active-low latch control: falling edge captures current A2/A1/A0 state for persistent channel hold |
| 15 (A0) | Address Bit 0 Input | LSB of 3-bit BCD address; works with A1 and A2 to select one of eight channels |
| 16 (EN) | Enable Input | Active-high global enable: disables all switches when low, enabling cascaded multiplexer designs |
| 17 (V–) | Negative Supply Rail | Accepts –4.5V to –20V (dual) or 0V (single supply); substrate tied to V+ for latch stability |
| 18 (A2) | Address Bit 2 Input | MSB of 3-bit BCD address; completes full 1-of-8 decoding with A1 and A0 |
Key Features
| Feature | Design Value |
|---|---|
| On-board address latches | Eliminates need for continuous µP address bus drive-latched state persists after WR pulse, reducing bus loading and timing constraints |
| Break-before-make switching | Guarantees 0.2µs minimum open interval between channel disconnect and reconnect, preventing cross-conduction in sensitive analog paths |
| TTL/CMOS logic compatibility | Input thresholds (~1.6V) and leakage (<1µA) allow direct interface with 5V µPs, FPGAs, and logic families without level shifters |
| Microprocessor-bus compatibility | WR/RS strobes and transparent/latched modes align with standard µP timing protocols (e.g., 8080/8086 bus cycles) |
| Pin and electrical compatibility | Drop-in replacement for industry-standard DG528 and ADG528 devices-no PCB or firmware changes required |
Applications
| Data-Acquisition Systems | Automatic Test Equipment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG528AKRZ | Pin-compatible 1-of-8 latchable mux; rDS(ON) = 470Ω (max) at ±15V; higher charge injection (12pC); operates from –40°C to +125°C | Preferred where extended temperature range is mandatory and slightly higher on-resistance is acceptable | Select ADG528AKRZ when operating beyond +85°C or requiring enhanced thermal robustness in aerospace deployments |
| DG528DN+ | Same function but in 20-pin PLCC package; identical electrical specs; no lead-free option; requires different footprint and reflow profile | Suitable for legacy board designs using PLCC sockets or where SOIC thermal dissipation is insufficient | Choose DG528DN+ only when mechanical constraints mandate PLCC packaging or socket-based field maintenance |
Compared with DG528EWN+T, ADG528AKRZ offers wider temperature tolerance but higher on-resistance and charge injection, while DG528DN+ provides identical functionality in a larger, socket-compatible package-neither is pin-compatible with DG528EWN+T's 18-pin wide SOIC footprint.

FAQ
What is the maximum supply voltage rating for DG528EWN+T?
The DG528EWN+T has an absolute maximum V+ rating of +44V and V– rating of –44V referenced to GND, but its specified operational range is ±4.5V to ±20V for dual supplies or +5V to +30V for single supplies. Exceeding ±20V may degrade rDS(ON) stability and increase leakage, so DG528EWN+T should be operated within those limits for guaranteed performance.
Does DG528EWN+T support single-supply operation with ground-referenced analog signals?
Yes, DG528EWN+T supports single-supply operation: connect V– to GND, apply V+ between +5V and +30V, and route analog signals from 0V to V+. For example, with V+ = +15V, DG528EWN+T switches 0V to +15V signals cleanly. Digital inputs remain TTL-compatible because thresholds are referenced to GND, not V–.
How does the WR (Write) strobe function in DG528EWN+T?
In DG528EWN+T, the WR strobe is active-low: a falling edge latches the current A2/A1/A0 address state, holding the selected channel indefinitely until WR goes low again or RS is asserted. While WR is high, DG528EWN+T remains in latched mode-address lines can change without affecting the output, enabling bus sharing and reduced µP overhead.
Can DG528EWN+T be used in differential signal paths?
No, DG528EWN+T is a single-ended 1-of-8 multiplexer. For differential applications, Maxim offers the DG529EWN+T-a 2-of-8 differential mux with matched SxA/SxB pairs per channel. DG528EWN+T lacks complementary output structure and timing matching required for true differential switching.
Is DG528EWN+T RoHS compliant and lead-free?
Yes, DG528EWN+T is RoHS compliant and manufactured with lead-free terminations per JEDEC J-STD-609. The "+T" suffix denotes tape-and-reel packaging with Pb-free (lead-free) finish, verified per Maxim's product change notices and Aetrix Electronics' traceable sourcing documentation for DG528EWN+T.
