Product details
Overview
DG528AK/883B from Maxim Integrated is a military-grade, single-ended 1-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), and rDS(ON) < 400Ω at ±15V - used in avionics data-acquisition systems requiring latch-controlled channel selection under extreme temperature conditions.
For engineers reviewing the DG528AK/883B datasheet, DG528AK/883B pinout, DG528AK/883B application, or DG528AK/883B equivalent, key selection criteria include MIL-STD-883B processing, -55°C to +125°C operating range, TTL/CMOS-compatible digital inputs, 18-pin CERDIP package, and verified break-before-make timing for signal integrity in high-reliability analog routing.
Technical Context
The DG528AK/883B implements an 8-channel analog switch matrix controlled by three address bits (A2/A1/A0), enable (EN), write (WR), and reset (RS) strobes - all internally latched to eliminate microprocessor bus contention. Its parallel N/P MOSFET switch architecture ensures rail-to-rail analog conduction with minimal charge injection (4pC typical).
It supports transparent mode (WR low, RS high) for nonlatching operation and latched mode (WR high) for persistent channel selection. Reset (RS low) forces all switches off and clears latches - critical for deterministic startup in safety-critical systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V (with ±15V supplies); supports full-rail switching without clipping in precision instrumentation |
| rDS(ON) | < 400Ω (typ. 270Ω at ±15V); ensures low insertion loss and minimal voltage drop in sensor signal paths |
| Break-Before-Make Interval | 0.2µs (min); prevents momentary shorting between input channels during switching |
| Charge Injection | 4pC (typ.); limits voltage glitch on high-impedance nodes like ADC sample capacitors |
| Off Isolation | 68dB (min); suppresses crosstalk between unselected channels in multi-signal environments |
| Supply Current | +2.5mA / -1.5mA (max); enables low-power operation in battery-backed or thermally constrained avionics modules |
| Operating Temperature | -55°C to +125°C; qualified per MIL-STD-883B for deployment in engine-mounted or space-grade systems |
Pinout & Package
Package: 18-pin CERDIP (Ceramic Dual-In-Line Package), hermetically sealed, lead finish gold-plated, suitable for high-reliability military and aerospace applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (RS) | Reset Strobe Input | Active-low signal that clears all latches and disables all switches - used for system-level initialization or fault recovery |
| 2 (A1) | Address Bit 1 Input | Second binary address bit for 1-of-8 channel decoding; TTL/CMOS compatible with 1.6V threshold |
| 3 (GND) | Analog/Digital Ground | Common reference for analog signals and logic; requires low-impedance connection to minimize noise coupling |
| 4 (V+) | Positive Supply Rail | Accepts +5V to +30V (single) or up to +20V (dual); powers analog switch core and level translators |
| 5–12 (S1–S8) | Analog Switch Inputs | Eight independent single-ended analog inputs; each connects to output D when selected via A2/A1/A0 |
| 13 (D) | Common Analog Output | Single output node shared across all eight channels; routed to downstream circuitry (e.g., ADC input) |
| 14 (WR) | Write Strobe Input | Active-low latch control: falling edge captures current A2/A1/A0 state for persistent channel selection |
| 15 (A0) | Address Bit 0 Input | LSB of 3-bit address; determines channel 1/3/5/7 vs. 2/4/6/8 selection when combined with A1/A2 |
| 16 (EN) | Enable Input | Active-high global enable; disables all switches when low - enables cascading multiple DG528AK/883B units |
| 17 (V-) | Negative Supply Rail | Accepts -4.5V to -20V (dual supply); required for bipolar analog signal handling (e.g., ±10V sensor outputs) |
| 18 (A2) | Address Bit 2 Input | MSB of 3-bit address; selects upper or lower half of 8-channel set (channels 5–8 vs. 1–4) |
Key Features
| Feature | Design Value |
|---|---|
| On-board address latches | Eliminates need for external latch ICs and reduces PCB footprint in microprocessor-controlled test equipment |
| Break-before-make switching | Guarantees 0.2µs minimum open interval between channel disconnect and reconnect - prevents signal shorting in multiplexed sensor arrays |
| MIL-STD-883B qualification | Includes screening for thermal cycling (-55°C to +125°C), mechanical shock, and radiation tolerance - required for flight-critical avionics |
| TTL/CMOS logic compatibility | 1.6V input threshold with ±3mV/°C drift ensures reliable interface with legacy 5V microcontrollers and FPGAs across full temperature range |
| Single/dual supply flexibility | Operates from +5V to +30V (single) or ±4.5V to ±20V (dual); enables use with existing ±15V op-amp rails or +24V industrial power buses |

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 not MIL-qualified; -40°C to +85°C commercial temp grade; higher rDS(ON) (450Ω typ.) | Lacks MIL-STD-883B screening and extended temperature range - unsuitable for flight hardware or space missions | Select only for cost-sensitive industrial prototypes where military reliability is not mandated. |
| MAX4617CSE+ | Non-latching 8-channel mux; no WR/RS/EN controls; smaller 16-pin SO package; lower supply voltage (±5V to ±20V) | Requires external latch logic; lacks deterministic reset behavior - inappropriate for safety-critical deterministic sequencing | Choose only when board space is constrained and microprocessor handles full address management without latch retention needs. |
Compared with ADG528AKRZ-REEL7 and MAX4617CSE+, the DG528AK/883B uniquely delivers MIL-STD-883B qualification, guaranteed -55°C to +125°C operation, and integrated latching - making it the sole option for avionics, missile guidance, and nuclear instrumentation where latch persistence and environmental survivability are non-negotiable.

FAQ
What is the maximum supply voltage rating for DG528AK/883B?
The DG528AK/883B has an absolute maximum V+ rating of +44V and V- rating of -44V relative to GND, but its specified operational range is ±4.5V to ±20V for dual supplies or +5V to +30V for single supply. Exceeding ±20V may degrade rDS(ON) stability and increase leakage - always observe derating curves in the datasheet for long-term reliability.
Does DG528AK/883B support single-supply operation with ground-referenced analog signals?
Yes, DG528AK/883B supports single-supply operation: tie V- to GND, apply +5V to +30V to V+, and route analog signals between 0V and V+. For example, with +15V supply, it switches 0V–15V signals cleanly. Digital inputs remain TTL/CMOS compatible because thresholds track GND, not V-.
How does the break-before-make timing work in DG528AK/883B?
DG528AK/883B guarantees a minimum 0.2µs open interval (tOPEN) between disconnecting one channel and connecting the next - measured from 90% switch-off to 10% switch-on. This prevents transient shorts during address changes and is validated across -55°C to +125°C, ensuring signal integrity in high-precision data acquisition.
Is DG528AK/883B pin-compatible with standard DG528 devices?
Yes, DG528AK/883B is pin- and electrically compatible with industry-standard DG528 and ADG528 devices in the same 18-pin CERDIP package. However, its MIL-STD-883B processing, extended temperature range, and enhanced screening make it functionally superior - no PCB redesign is needed when upgrading from commercial-grade variants.
What is the role of the EN (Enable) pin in DG528AK/883B?
The EN pin is an active-high global enable: when low, all eight switches are forced off regardless of address or WR state - enabling safe power-up sequencing and cascade configurations. In DG528AK/883B, EN retains full functionality across -55°C to +125°C and draws less than 1µA, supporting low-power standby modes in battery-operated systems.
