Product details
Overview
DG529AK/883B from Maxim Integrated is a military-grade, differential 2-of-8 CMOS analog multiplexer with on-board address latches, break-before-make switching, ±4.5V to ±20V dual-supply operation, and -55°C to +125°C temperature range-designed for high-reliability avionics and data-acquisition systems requiring precise channel isolation and latch-controlled signal routing.
For engineers reviewing the DG529AK/883B datasheet, DG529AK/883B pinout, DG529AK/883B application, or DG529AK/883B equivalent, this page delivers verified electrical parameters, MIL-STD-883B-qualified package details, truth-table–validated logic behavior, and direct alternatives for ruggedized analog multiplexing in safety-critical embedded systems.
Technical Context
The DG529AK/883B implements a dual-channel differential architecture: each of its four differential pairs (IN1A/IN1B through IN4A/IN4B) routes to corresponding outputs OUTA/OUTB under BCD address control (A1, A0), with independent enable (EN), write (WR), and reset (RS) strobes. Its internal structure uses parallel N/P MOSFET switches and level-shifted TTL/CMOS-compatible input translators.
All digital inputs (A1, A0, EN, WR, RS) feature guaranteed 1.6V threshold referenced to GND, ±2V overvoltage tolerance, and <1µA leakage; analog performance is defined by rDS(ON) ≤ 450Ω (TYP), charge injection ≤ 4pC, and off-isolation ≥ 68dB at 500kHz-enabling accurate low-distortion signal selection in precision measurement paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V (with ±15V supplies); supports full-rail switching across V− to V+ without distortion |
| rDS(ON) | ≤450Ω typical - ensures minimal voltage drop and gain error in sensor/ADC front-end paths |
| Off Isolation (OIRR) | ≥68dB at 500kHz - prevents crosstalk between inactive differential channels in multi-sensor systems |
| Charge Injection | ≤4pC - limits settling error and pedestal shift in sampled-data acquisition circuits |
| Break-Before-Make Interval | ≤0.2µs - eliminates momentary shorting during channel transitions in fault-tolerant designs |
| Supply Range | ±4.5V to ±20V dual supply or +5V to +30V single supply - enables flexible power architecture in mixed-signal platforms |
| Operating Temperature | −55°C to +125°C - qualified per MIL-STD-883B for deployment in aerospace, defense, and downhole instrumentation |

| 9 (DB) | Differential Output Common B | Shared return path for all SxB pins; requires dedicated low-noise ground plane |
| 10 (WR) | Write Strobe Input | Latches current A1/A0 state; enables transparent mode when low, holds selection when high |
| 11 (A0) | Address Bit 0 | LSB of 2-bit BCD address; combined with A1 selects one of four differential channel pairs |
| 12 (EN) | Enable Input | Active-high global enable; allows software-controlled shutdown of all analog paths without address change |
| 13 (V−) | Negative Supply Rail | Connects to −4.5V to −20V; establishes analog common-mode range and switch bias |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential analog multiplexing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG529FQ/883B | Higher rDS(ON) (550Ω TYP), lower OIRR (60dB), same 18-pin CERDIP and MIL-STD-883B qualification | Acceptable where higher on-resistance and reduced isolation are tolerable in non-critical measurement paths | Select ADG529FQ/883B only if legacy ADI supply chain alignment is required and performance margin permits 100Ω higher rDS(ON). |
| HI509AJ/883B | No on-board latches; requires external address register; identical pinout but lacks WR/RS strobes and EN control | Suitable for fixed-address or manually controlled systems where µP bus interfacing is not needed | Choose HI509AJ/883B only when latch-free operation simplifies timing design and board space allows external latch ICs. |
Compared with DG529AK/883B, ADG529FQ/883B trades 100Ω higher on-resistance and 8dB lower off-isolation for ADI ecosystem compatibility, while HI509AJ/883B removes latch functionality entirely-making DG529AK/883B the sole option for µP-bus–driven, latch-retentive differential multiplexing in MIL-spec environments.

FAQ
What is the maximum analog signal voltage range supported by the DG529AK/883B?
The DG529AK/883B supports an analog signal range of ±15V when operated with ±15V supplies, and scales linearly with supply voltage up to ±20V. With single +30V supply and V− tied to GND, it handles 0V to +30V signals. This range is guaranteed across the full −55°C to +125°C operating temperature and validated per MIL-STD-883B test conditions.
Does the DG529AK/883B require external latching circuitry when used with a microprocessor bus?
No, the DG529AK/883B does not require external latching circuitry. It integrates on-board address latches controlled by WR and RS strobes, allowing direct connection to µP data/address buses. When WR goes high, the current A1/A0 state is latched and held indefinitely-eliminating the need for external 74HC373 or similar latch ICs in embedded DAQ designs.
How does the break-before-make interval of the DG529AK/883B prevent signal corruption?
The DG529AK/883B guarantees a break-before-make interval of ≤0.2µs, ensuring that one channel fully disconnects before the next connects. This prevents momentary shorting between analog sources-critical in applications like sensor multiplexing where source impedance mismatches could cause transient loading, voltage spikes, or measurement errors in high-precision ADC front-ends.
Is the DG529AK/883B pin-compatible with commercial-grade DG529 variants?
Yes, the DG529AK/883B shares identical pinout and electrical interface with commercial DG529CJ, DG529CK, and DG529EWN variants. All use the same 18-pin DIP/SO/CERDIP footprint and logic-level definitions, enabling drop-in replacement in existing layouts-provided thermal, radiation, and reliability requirements align with the MIL-STD-883B qualification of DG529AK/883B.
What is the role of the EN (Enable) pin in DG529AK/883B system-level operation?
The EN pin provides global software-controlled shutdown of all analog channels in the DG529AK/883B. When EN is low, all differential switches turn off regardless of address or latch state-enabling safe power sequencing, fault isolation, and cryptographic key rotation in secure communication systems. This function is retained across the full −55°C to +125°C range and verified under MIL-STD-883B environmental stress.
