Product details
Overview
DG506AMWI/PR from Maxim Integrated is a monolithic CMOS 16-channel analog multiplexer (1-of-16) with break-before-make switching, ±4.5V to ±18V dual-supply operation, and -55°C to +125°C extended temperature range. It features 270Ω typical on-resistance, <1nA off-leakage at 25°C, and 0.6μs transition time - enabling precision signal routing in high-reliability data acquisition and control systems.
For engineers reviewing the DG506AMWI/PR datasheet, DG506AMWI/PR pinout, DG506AMWI/PR application, or DG506AMWI/PR equivalent, key selection criteria include its wide supply range, latch-up immunity under powered-off signal conditions, guaranteed performance across military temperature extremes, and compatibility with legacy IH6116/DG506A footprints.
Technical Context
The DG506AMWI/PR implements a fully symmetrical, bidirectional analog switch matrix controlled by four TTL/CMOS-compatible address inputs (A0–A3) and an active-high enable (EN). Its break-before-make architecture prevents momentary channel shorting during address transitions.
It operates with true rail-to-rail analog signal handling (±15V range), low charge injection (<0.5pC), and maintains sub-6pF off-capacitance - critical for minimizing crosstalk and settling errors in multiplexed ADC front-ends and precision instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Channels | 16-channel (1-of-16) unidirectional/bidirectional analog multiplexer |
| Supply Range | ±4.5V to ±18V - supports industrial and aerospace dual-rail systems without level-shifting |
| On-Resistance | 270Ω typical (VD = ±10V, IS = −200μA) - ensures minimal gain error in sensor signal paths |
| Off-Leakage Current | ±1nA max at 25°C - preserves accuracy in high-impedance measurement circuits |
| Transition Time | 0.6μs typical - enables sampling rates up to ~1.2MHz in time-multiplexed systems |
| Temperature Range | −55°C to +125°C - qualified for MIL-STD-883 Class B applications |
| Off-Isolation | 68dB at 500kHz - suppresses crosstalk between inactive channels in dense signal routing |
Pinout & Package
Package: 28-pin Wide SO (SOIC-Wide), RoHS-compliant, body width 7.6mm, thermal pad not included.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | V+ | Positive supply input - must be decoupled locally to minimize switching noise coupling |
| 2,3 | N.C. | No internal connection - left floating per datasheet; no PCB trace required |
| 4–11 | S16–S9 | Analog input/output channels 16 through 9 - bidirectional, symmetric signal path |
| 12 | GND | Analog/digital ground reference - separate low-impedance return path recommended |
| 13,14 | N.C. | No internal connection - electrically isolated; avoid routing sensitive signals nearby |
| 15–17 | A2, A1, A0 | Address inputs (LSB first) - decode channel selection; compatible with TTL/CMOS logic levels |
| 18 | EN | Enable control - high = active; low = all switches open; fast 1μs turn-on/off timing |
| 19–26 | S1–S8 | Analog input/output channels 1 through 8 - paired with S9–S16 for full 16-channel set |
| 27 | V− | Negative supply input - requires independent decoupling from V+ for optimal PSRR |
| 28 | D | Common analog output/input terminal - connects to ADC input or DAC output node |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed 0.2μs minimum open interval prevents channel overlap and signal shorting |
| Latch-up proof construction | Immune to latch-up even when power supplies are off but analog signals remain applied |
| Symmetrical bidirectional operation | Identical on-resistance and leakage in either direction - supports flexible signal flow design |
| TTL/CMOS logic compatibility | Accepts 0.8V/2.4V thresholds - interfaces directly with microcontrollers and FPGAs without buffers |
| Low power consumption | 0.13mA positive supply current - reduces thermal load in portable and sealed systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Intersil IH6116 | Same pinout and function; higher 400Ω typical RDS(ON), wider 10nA leakage spec | Qualified to MIL-STD-883 but lacks Maxim's latch-up immunity guarantee under powered-off conditions | Select IH6116 only if legacy qualification documentation is mandatory and power sequencing cannot be controlled. |
| Harris HI506 | Identical 28-pin SO footprint; 350Ω typical RDS(ON); no guaranteed break-before-make timing | Rated only to −55°C to +125°C in CERDIP; SO version has limited temperature validation | Prefer HI506 only for cost-sensitive non-mission-critical applications where 0.2μs tOPEN is not required. |
Compared with IH6116 and HI506, the DG506AMWI/PR delivers lower on-resistance, tighter leakage control, guaranteed break-before-make timing, and documented latch-up immunity - making it the preferred choice for new designs requiring robustness and precision in harsh environments.

FAQ
What is the maximum analog signal voltage range supported by the DG506AMWI/PR?
The DG506AMWI/PR supports a continuous analog signal range of ±15V when operated with ±15V supplies. Its absolute maximum ratings allow V+ up to +44V and V− down to −44V, but functional analog swing remains rail-to-rail within the applied supply rails. This makes DG506AMWI/PR suitable for interfacing with industrial sensors and transducers delivering signals up to ±10V without attenuation or clipping.
Does the DG506AMWI/PR require external pull-up or pull-down resistors on address lines?
No, the DG506AMWI/PR does not require external pull-up or pull-down resistors on A0–A3 or EN pins. Its address and enable inputs are TTL/CMOS compatible with defined logic thresholds (VAL ≤ 0.8V for low, VAH ≥ 2.4V for high) and exhibit low input current (±0.002μA typical), allowing direct connection to microcontroller GPIOs or FPGA outputs without additional biasing components.
How does the break-before-make timing of the DG506AMWI/PR prevent signal corruption?
The DG506AMWI/PR guarantees a minimum 0.2μs break interval between channel disconnect and next channel connect, preventing momentary shorting of analog sources. This eliminates transient glitches and cross-talk during channel switching - critical when multiplexing high-impedance sensors or voltage references where even nanosecond overlaps can cause measurement errors or damage.
Is the DG506AMWI/PR pin-compatible with the original Siliconix DG506A in Wide SO package?
Yes, the DG506AMWI/PR is fully pin-compatible with Siliconix DG506ACWI in the 28-pin Wide SO package, sharing identical pinout, electrical specifications, and thermal characteristics. Both parts use the W28-5 outline and support the same footprint, land pattern (90-0109), and soldering profiles - enabling drop-in replacement without PCB modification.
What is the thermal performance of the DG506AMWI/PR in continuous operation at +125°C?
At TA = +125°C, the DG506AMWI/PR maintains RDS(ON) ≤ 550Ω and off-leakage ≤ ±50nA, with continuous power dissipation derated to 1000mW × (1 − (125−70)/100) = 450mW. Its monolithic CMOS construction ensures stable parametric behavior across the full −55°C to +125°C range, validated per MIL-STD-883 methods for the DG506AMWI/PR variant.
