Product details
Overview
DG509AEWE from Maxim Integrated is a differential 4-channel (2-of-8) monolithic CMOS analog multiplexer with ±4.5V to ±18V dual-supply operation, break-before-make switching, and guaranteed latchup immunity during power-off signal presence. It features 500Ω typical on-resistance, <0.5nA off-leakage at ±10V, and 0.6μs switching time - enabling precision signal routing in high-reliability data-acquisition systems.
For engineers reviewing the DG509AEWE datasheet, DG509AEWE pinout, DG509AEWE application, or DG509AEWE equivalent, key selection criteria include its differential channel architecture, wide supply range compatibility, low leakage performance across -40°C to +85°C, and SOIC-Wide (16-pin) packaging for industrial-grade thermal and mechanical stability.
Technical Context
The DG509AEWE implements a fully decoded address logic (A0/A1) controlling four matched differential switch pairs (S1A/S1B through S4A/S4B), each capable of bidirectional analog signal flow. Its CMOS construction ensures symmetrical on-resistance and charge injection below 1pC, critical for sampling accuracy in multiplexed ADC front-ends.
Break-before-make timing is guaranteed at ≤0.2μs, preventing momentary shorting between differential paths. Enable control (EN) supports system-level power gating with 0.4μs turn-on and 0.2μs turn-off delays, while TTL/CMOS-compatible logic inputs simplify interface with microcontrollers and FPGAs.

| 2 | EN | Active-high enable controlling global switch conduction; disables all paths when low |
| 3 | V− | Negative supply rail connection; must be referenced to GND for proper biasing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX339EWE+ | Lower on-resistance (100Ω), but limited to ±5V supplies and narrower -40°C to +85°C temp range | Better for low-voltage portable instrumentation; unsuitable for ±12V/±15V industrial systems | Select MAX339EWE+ only if supply rails are constrained to ±5V and lower on-resistance is prioritized over voltage range |
| ADG509ATQ | Same 16-pin TSSOP package, but higher 800Ω on-resistance and no guaranteed break-before-make timing | Acceptable for non-critical signal routing where channel crosstalk is less sensitive | Choose ADG509ATQ when footprint compatibility is required but strict B-B-M timing and leakage specs are not mandatory |
Compared with MAX339EWE+ and ADG509ATQ, DG509AEWE uniquely delivers ±18V operation, guaranteed break-before-make, and sub-picoamp leakage - making it the only option for high-voltage, high-fidelity differential multiplexing in mission-critical industrial and aerospace systems.

FAQ
What is the maximum analog signal voltage range supported by DG509AEWE?
DG509AEWE supports an analog signal range of ±15V, meaning it can accurately pass bipolar signals from -15V to +15V without distortion or clipping. This specification holds under standard operating conditions with V+ = +15V and V− = −15V. Operation outside this range requires verification against absolute maximum ratings to avoid damage.
Does DG509AEWE guarantee break-before-make switching behavior?
Yes, DG509AEWE guarantees break-before-make switching with a maximum open interval (tOPEN) of 0.2μs. This ensures no momentary short circuit occurs between differential channel pairs during address transitions - a critical requirement for protecting downstream circuitry in precision measurement and control applications using DG509AEWE.
What is the operating temperature range for DG509AEWE?
DG509AEWE is rated for operation from -40°C to +85°C, as indicated by the "E" grade suffix in its part number. This extended industrial temperature range makes DG509AEWE suitable for deployment in demanding environments such as factory automation, avionics, and outdoor instrumentation where thermal stability is essential.
How does DG509AEWE handle power-supply sequencing and signal presence during power-down?
DG509AEWE uses latchup-proof CMOS construction that guarantees immunity to destructive latchup even when analog input signals remain present while power supplies are turned off. This feature protects the device and connected circuitry during brownout or controlled shutdown sequences - a documented reliability advantage of DG509AEWE over earlier-generation multiplexers.
What package type is used for DG509AEWE and why is it significant?
DG509AEWE uses a 16-pin Wide SO (SOIC-W) package with 1.27mm pitch and 0.3-inch body width. This package offers superior thermal resistance (762mW at +70°C) and mechanical robustness compared to narrow SO variants, making DG509AEWE more reliable in high-vibration or thermally cycling applications common in industrial and aerospace deployments.
