Product details
Overview
DG406DY-T from Intersil is a single 16-channel CMOS analog multiplexer IC used for high-precision signal routing in data acquisition and instrumentation systems. It features 100 Ω max ON-resistance, <300 ns transition time, ±15 V dual-supply operation, and TTL/CMOS-compatible logic inputs. The device enables bidirectional analog signal switching across 16 bilateral channels with low charge injection (40 pC) and <5% rDS(ON) matching - critical for sample-and-hold and medical sensor front-ends.
For engineers reviewing the DG406DY-T datasheet, DG406DY-T pinout, DG406DY-T application, or DG406DY-T equivalent, key selection criteria include its 28-pin SOIC package, -40°C to +85°C operating range, 44 V absolute max supply rating, and compatibility with ±15 V or 12 V single-supply configurations in battery-powered and Hi-Rel systems.
Technical Context
The DG406DY-T integrates a 4-bit address decoder, enable-controlled channel selection, internal voltage reference for stable logic thresholds, and 16 matched bilateral analog switches fabricated using a high-voltage silicon-gate process. Its epitaxial layer prevents latch-up under transient stress.
It operates with single-supply (V+ = 12 V, V− = 0 V) or split-supply (±15 V) configurations, supporting analog signal ranges up to ±10 V or 0–12 V. Logic inputs accept TTL/CMOS levels (VINL ≤ 0.8 V, VINH ≥ 2.4 V), and the EN pin provides global on/off control with 200 ns typical turn-on delay.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel Count | 16-channel single-ended (1-of-16) analog multiplexer - routes one of 16 bidirectional analog inputs to common drain D. |
| ON-Resistance (rDS(ON)) | Max 100 Ω at ±10 V signal swing - ensures minimal gain error and signal attenuation in precision measurement paths. |
| Transition Time (tTRANS) | Max 300 ns (±15 V supply) - supports multiplexing rates up to ~3 MHz in fast-sampling ADC interfaces. |
| Charge Injection | 40 pC typical - reduces hold-step error and simplifies anti-aliasing filter design in sample-and-hold circuits. |
| Supply Voltage Range | ±15 V dual or 12 V single - enables direct interfacing with industrial ±10 V sensors and battery-operated 3.3/5/12 V systems. |
| Logic Compatibility | TTL and CMOS input thresholds (0.8 V low / 2.4 V high) - allows direct connection to microcontrollers and FPGAs without level-shifting. |
| Leakage Currents | ID(OFF) ≤ 1 nA (DG406), IS(OFF) ≤ 0.5 nA - preserves accuracy in high-impedance sensor nodes and low-power standby modes. |
Pinout & Package
Package: 28-lead SOIC (M28.3), RoHS-compliant, wide-body plastic package with 1.27 mm lead pitch. Dimensions: 17.7–18.1 mm × 7.4–7.6 mm × 2.35–2.65 mm height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 27 | V+, V− | Positive and negative power rails - support ±15 V operation; V− tied to GND for single-supply use. |
| 12 | GND | Analog/digital ground reference - must be low-impedance return path for all analog signals and digital logic. |
| 4–11, 19–26 | S16–S9, S1–S8 | 16 source switch terminals - bidirectional, interchangeable as inputs or outputs; equally matched for AC signals. |
| 28 | D | Common drain terminal - single output node connected to ADC, buffer, or signal chain downstream. |
| 14–17 | A3–A0 | 4-bit binary address inputs - select active channel (0–15); A3 MSB, A0 LSB per truth table. |
| 18 | EN | Active-high enable - disables all switches when low; required for multi-mux synchronization or power gating. |
| 2, 3, 13 | NC | No-connect pins - no internal connection; must remain unconnected per datasheet. |
Key Features
| Feature | Design Value |
|---|---|
| Bilateral Switching | All 16 channels support bidirectional analog signal flow - eliminates need for direction-aware routing in transducer interfaces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX406CPN+ | 16-channel, 100 Ω rDS(ON), but only rated for ±12 V supplies and lacks internal VREF; higher 500 ns tTRANS. | Less suitable for ±15 V industrial sensors or high-speed sampling >1 MHz. | Select DG406DY-T when ±15 V operation, faster switching, or integrated logic threshold reference is required. |
| ADG406BRUZ | 16-channel, 70 Ω rDS(ON), 125 ns tTRANS, but requires external VREF and has higher 100 pC charge injection. | Better for ultra-low ON-resistance needs, but demands additional reference circuitry and tighter hold-capacitor sizing. | Choose DG406DY-T for simplified layout, lower charge injection, and guaranteed latch-up immunity in harsh environments. |
Compared with MAX406CPN+ and ADG406BRUZ, the DG406DY-T delivers superior combination of ±15 V tolerance, 40 pC charge injection, and integrated voltage reference - reducing BOM count and improving reliability in medical and test equipment where signal fidelity and supply flexibility are critical.

FAQ
What is the maximum analog signal voltage range supported by the DG406DY-T?
The DG406DY-T supports analog signals up to ±10 V when operated with ±15 V supplies, and 0–12 V with a 12 V single supply. Its 44 V absolute maximum V+–V− rating permits safe handling of 30 VP-P signals, making it suitable for industrial ±10 V sensor interfaces. This specification is confirmed in the Absolute Maximum Ratings and Electrical Specifications sections of the FN3116 datasheet.
Does the DG406DY-T require external components for logic-level translation?
No, the DG406DY-T does not require external level-shifting components. Its TTL/CMOS-compatible inputs accept logic low ≤ 0.8 V and logic high ≥ 2.4 V directly - fully compatible with standard 3.3 V and 5 V microcontrollers and FPGAs. An internal voltage reference stabilizes threshold behavior across temperature and supply variations, as documented in the Functional Diagram and Electrical Specifications.
How does the DG406DY-T handle power supply sequencing during startup?
The DG406DY-T has no strict power supply sequencing requirement. It operates correctly whether V+ or V− is applied first, provided both rails settle within specification before enabling the device. The internal epitaxial structure prevents latch-up during asymmetric ramp-up, and the ENABLE pin allows controlled activation after supplies stabilize - a key advantage over older DG506A-series devices.
Can the DG406DY-T be used in single-supply 3.3 V systems?
The DG406DY-T is not specified for 3.3 V-only operation. Its minimum recommended supply is 12 V single (V+ = 12 V, V− = 0 V) or ±5 V dual. At 3.3 V, rDS(ON) increases significantly (>500 Ω), leakage rises, and logic thresholds become unreliable. For low-voltage systems, consider purpose-built 3.3 V multiplexers like the TMUX1574 instead of the DG406DY-T.
What is the thermal resistance (θJA) of the DG406DY-T in its SOIC package?
The DG406DY-T in 28-lead SOIC (M28.3) package has a typical junction-to-ambient thermal resistance (θJA) of 75°C/W, measured on a low-thermal-conductivity test board in free air. This value is specified in the Thermal Information section of the FN3116 datasheet and is critical for calculating maximum power dissipation under worst-case ambient conditions.
