Product details
Overview
DG528CCWN+ 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 - used in microprocessor-controlled data-acquisition systems for reliable channel selection under bus timing constraints.
For engineers reviewing the DG528CCWN+ datasheet, DG528CCWN+ pinout, DG528CCWN+ application, or DG528CCWN+ equivalent, key selection considerations include latchable address control, rDS(ON) < 400Ω at ±15V, 0.2µs break-before-make interval, and compatibility with industry-standard DG528/DG529 footprints and logic interfaces.
Technical Context
The DG528CCWN+ integrates parallel N- and P-channel MOSFET switch pairs per channel, driven by internal level-shifted translators and a 3-bit BCD decoder. Its latch architecture accepts A2/A1/A0 addresses and holds channel selection indefinitely after a WR strobe, eliminating continuous bus addressing.
It supports transparent mode (WR low, RS high), latched mode (WR high), and reset mode (RS low), with EN enabling global switch disable. Digital thresholds remain stable (~1.6V) across supply voltages and temperature, ensuring robust TTL interfacing even at ±5V supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V (with ±15V supplies); supports 0V to +15V with single +15V supply and V− tied to GND |
| rDS(ON) | < 400Ω typical at ±15V - ensures minimal signal attenuation and voltage drop in precision analog paths |
| Break-Before-Make Interval | 0.2µs - prevents momentary shorting between input channels during switching |
| Charge Injection | 4pC - limits transient voltage error on high-impedance nodes (e.g., sample-hold capacitors) |
| Enable Turn-On Time | 1.0–1.5µs - enables fast channel activation under microprocessor control |
| Supply Current | ±0.003mA to ±0.01mA - ultra-low quiescent power ideal for battery-backed or energy-sensitive systems |
| Logic Compatibility | TTL and CMOS - operates directly with 5V µP buses without level-shifting |
Pinout & Package
Package: 18-pin Wide SO (Small Outline), 0.300-inch body width, RoHS-compliant, surface-mount.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (RS) | Reset Strobe Input | Active-low signal that clears all latches and disables all channels - used for system initialization or fault recovery |
| 2 (A1) | Address Bit 1 Input | BCD address line; combined with A0 and A2 to select one of eight analog inputs |
| 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 (S1B) | Channel 1 Analog Output (DG529 only) | Not connected on DG528CCWN+ - DG528 is single-ended; this pin is NC for this part |
| 6 (S2B) | Channel 2 Analog Output (DG529 only) | No-connect on DG528CCWN+ - confirms device identity as DG528, not DG529 |
| 7 (S3B) | Channel 3 Analog Output (DG529 only) | NC on DG528CCWN+ - distinguishes pinout from differential DG529 variant |
| 8 (S4B) | Channel 4 Analog Output (DG529 only) | NC on DG528CCWN+ - validates single-ended 1-of-8 topology |
| 9 (DB) | Differential Output (DG529 only) | No-connect - confirms DG528CCWN+ lacks differential output capability |
| 10 (WR) | Write Strobe Input | Active-low latch enable; captures A2/A1/A0 state on falling edge to hold channel selection |
| 11 (A0) | Address Bit 0 Input | LSB of 3-bit BCD address; determines odd/even channel selection with A1 and A2 |
| 12 (EN) | Enable Input | Active-high global switch control; disables all channels when low - critical for cascading or power gating |
| 13 (V−) | Negative Supply Rail | Accepts −4.5V to −20V (dual) or 0V (single supply); substrate tied to V+ per datasheet |
| 14 (S1A) | Channel 1 Analog Input | First of eight single-ended analog inputs - routed to common output (pin 18) when selected |
| 15 (S2A) | Channel 2 Analog Input | Second analog input; shares same output path as S1A–S8A under address control |
| 16 (S3A) | Channel 3 Analog Input | Third analog input; identical electrical specs (rDS(ON), leakage, capacitance) as S1A |
| 17 (S4A) | Channel 4 Analog Input | Fourth analog input; pinout symmetry supports PCB layout reuse across channel groups |
| 18 (D) | Common Analog Output | Single output node for all eight channels - requires external buffering for driving ADC inputs or cables |
Key Features
| Feature | Design Value |
|---|---|
| On-board address latches | Eliminates need for external latch ICs or continuous µP address bus drive - reduces component count and board space in embedded DAQ systems |
| Break-before-make switching | Guarantees 0.2µs minimum open interval between channel disconnect and reconnect - prevents signal shorting in mixed-signal routing |
| rDS(ON) < 400Ω (typ) | Minimizes gain error and THD in precision sensor signal chains operating at ±15V supplies |
| TTL/CMOS logic compatibility | Direct interface with 5V microcontrollers and FPGAs without level shifters - simplifies timing-critical control paths |
| Wide supply range (+5V to +30V / ±4.5V to ±20V) | Supports legacy industrial rails (±15V), modern low-voltage systems (+5V), and asymmetric configurations (e.g., +15V/−5V) |
Applications
| Automated Test Equipment (ATE) | Data Acquisition Systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 1-of-8 latchable analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG528AKRZ-REEL7 | Pin-compatible but rated for −55°C to +125°C; rDS(ON) = 450Ω max (vs. 400Ω typ for DG528CCWN+); higher charge injection (8pC) | Suitable for extended-temperature military/aerospace use where DG528CCWN+'s 0°C to +70°C range is insufficient | Select ADG528AKRZ-REEL7 only when full MIL-STD-883 qualification or extended temperature operation is required |
| MAX4617ESA+ | Non-latching 8-channel mux; no on-board address latches or WR/RS pins; rDS(ON) = 60Ω typ; requires external latch logic | Better for high-speed, non-µP-controlled routing where latch functionality is unnecessary and lower on-resistance is critical | Choose MAX4617ESA+ when minimizing rDS(ON) and propagation delay outweighs the benefit of integrated latching |
Compared with ADG528AKRZ-REEL7, DG528CCWN+ offers lower typical rDS(ON) and lower charge injection but lacks extended temperature rating; versus MAX4617ESA+, DG528CCWN+ trades 340Ω higher on-resistance for full µP-bus integration and reduced external component count.

FAQ
What is the operating temperature range for the DG528CCWN+?
The DG528CCWN+ is specified for 0°C to +70°C ambient operation. This commercial-grade temperature range is confirmed in the Ordering Information table, where "DG528C" suffix denotes the 0°C to +70°C grade, and "CWN" indicates the 18-pin wide SO package. It is not rated for extended or military temperature ranges.
Does the DG528CCWN+ support single-supply operation?
Yes, the DG528CCWN+ supports single-supply operation from +5V to +30V. When using a single supply, V− must be connected to GND. The analog signal range then spans 0V to V+, enabling compatibility with unipolar sensor interfaces and standard 5V/12V/15V systems without negative rails.
How does the WR (Write) pin function on the DG528CCWN+?
The WR pin on the DG528CCWN+ is an active-low strobe that latches the current A2/A1/A0 address state on its falling edge. Once latched, the selected channel remains active until WR goes low again or RS is asserted. This eliminates the need for continuous address bus drive from the microprocessor.
Is the DG528CCWN+ pin-compatible with the DG529 series?
No, the DG528CCWN+ is not pin-compatible with the DG529 series. While both share the 18-pin wide SO footprint, DG529 pins 5–9 (S1B–S4B, DB) are functional differential outputs, whereas those pins are no-connect on DG528CCWN+. The pin functions and truth tables differ fundamentally between single-ended (DG528) and differential (DG529) variants.
What is the maximum analog signal voltage the DG528CCWN+ can switch?
The DG528CCWN+ supports analog signals within the range of V− to V+. With ±15V supplies, it switches ±15V signals; with a +15V single supply and V− = GND, it switches 0V to +15V signals. Absolute maximum analog voltage is limited by the supply rails - exceeding V− or V+ risks damage or undefined behavior.
