Product details
Overview
DG441DY-T from Intersil is a monolithic quad SPST CMOS analog switch with TTL/CMOS-compatible digital inputs, 85Ω max ON resistance, 250ns max tON, ±20V analog signal range, and operation from single +5V to +34V or dual ±5V to ±22V supplies - used in precision sample-and-hold circuits, audio routing, and data acquisition systems.
For engineers reviewing the DG441DY-T datasheet, DG441DY-T pinout, DG441DY-T application, or DG441DY-T equivalent, this page delivers verified specifications, SOIC-16 package details, real-world switching performance metrics, logic polarity behavior (active-low control), and validated alternatives for analog signal path design.
Technical Context
The DG441DY-T implements four independent bilateral SPST switches using a high-voltage silicon-gate CMOS process with epitaxial isolation to prevent latch-up. Each channel supports bidirectional analog signals with low and flat ON-resistance variation across ±5V input range.
Its logic interface accepts standard TTL/CMOS voltage thresholds (≤0.8V low, ≥2.4V high), and its substrate-connected V+ pin enables stable operation under asymmetrical supply conditions up to 44V differential. Charge injection is minimized to ±1pC (typ), easing hold capacitor settling in precision sampling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ON Resistance (max) | 85Ω at +25°C, ±15V supplies - ensures minimal signal attenuation and gain error in precision resistor networks. |
| Turn-On Time (max) | 250ns with RL=1kΩ, CL=35pF - supports multiplexing of signals up to ~1MHz without significant timing skew. |
| Analog Signal Range | ±20V (max) - accommodates industrial sensor outputs and audio line-level signals without clipping. |
| Supply Range | Single: +5V to +34V; Dual: ±5V to ±22V - enables flexible integration into battery-powered and rail-to-rail systems. |
| Charge Injection | ±1pC (typ) - reduces droop and settling time in sample-and-hold applications using small hold capacitors. |
| OFF Isolation | 60dB at 1MHz - suppresses crosstalk between active and inactive channels in multi-channel data acquisition. |
| Logic Polarity | Active-low (INx = 0V → ON) - matches legacy DG201A drop-in replacement requirements and simplifies level-shifting. |
Pinout & Package
Package: 16-lead SOIC (M16.15), 3.9mm × 9.9mm body, 1.27mm pitch, RoHS-compliant Pb-free finish (annealed matte tin).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Active-low digital control inputs; drive each switch independently with TTL/CMOS logic levels. |
| 2, 7, 10, 15 | D1–D4 | Drain (output) terminals; bidirectional - function as either input or output depending on signal flow direction. |
| 3, 6, 11, 14 | S1–S4 | Source (input) terminals; matched to D pins for symmetrical AC performance and low THD. |
| 4 | V− | Negative supply rail; must be ≤ −25V relative to GND - sets lower bound of analog signal swing. |
| 5 | GND | Logic common reference; separate from analog return paths to minimize digital noise coupling. |
| 12 | NC | No internal connection - must remain unconnected; no pull-up/down or bypass required. |
| 13 | V+ | Positive supply and substrate connection; limits max analog voltage to ≤ +34V relative to GND. |
Key Features
| Feature | Design Value |
|---|---|
| Bilateral SPST architecture | Enables true bidirectional signal routing - critical for sensor excitation, transducer interfacing, and loop-back diagnostics. |
| Low charge injection (±1pC) | Minimizes voltage step on hold capacitors, reducing need for long settling delays in 12-bit+ data acquisition. |
| Drop-in DG201A/DG202 upgrade | Same pinout and logic behavior - allows direct PCB replacement without layout or firmware changes. |
| High-voltage silicon-gate process | Supports 44V max V+–V− differential and eliminates latch-up risk in noisy industrial environments. |
| TTL/CMOS-compatible inputs | Operates directly from microcontroller GPIOs or FPGA I/O banks without level-shifting circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | Quad SPST, 35Ω max rDS(ON), 100ns tON, but requires external V+ bias for >±15V operation; no V+ substrate pin. | Better speed/resistance for low-voltage (<±12V) precision instrumentation; less suitable for wide-supply industrial use. | Select MAX4617ESE+ when optimizing for bandwidth and ON-resistance below ±12V; retain DG441DY-T for 44V-rated systems. |
| ADG1412BRUZ | Quad SPST, 1.8Ω max rDS(ON), 100ns tON, but only rated to ±15V analog range and +125°C max junction temp. | Superior performance in high-accuracy, low-noise medical or lab equipment where supply rails are constrained. | Choose ADG1412BRUZ for ultra-low distortion and leakage in battery-powered portable instruments; DG441DY-T remains preferred for ruggedized field-deployed gear. |
Compared with MAX4617ESE+ and ADG1412BRUZ, the DG441DY-T trades some ON-resistance and speed for broader supply flexibility (up to ±22V), integrated substrate biasing, and proven reliability in high-voltage industrial ATE - making it the optimal choice where system-level voltage margin and drop-in compatibility are primary concerns.

FAQ
What is the logic polarity of the DG441DY-T?
The DG441DY-T uses active-low logic control: an input voltage ≤0.8V turns the corresponding switch ON, while ≥2.4V turns it OFF. This matches the DG201A pinout and simplifies replacement in existing designs without logic inversion. The DG441DY-T truth table confirms INx = 0V → Sx-Dx closed, and all four channels follow identical polarity behavior.
Can the DG441DY-T operate from a single 12V supply?
Yes, the DG441DY-T supports single-supply operation from +5V to +34V. At +12V, its analog signal range is 0V to +12V, rDS(ON) is ≤200Ω (max), and tON is ≤450ns. These values are specified in the datasheet's single-supply electrical characteristics table and validated across −40°C to +85°C, making it suitable for portable 12V systems like handheld test gear.
Does the DG441DY-T require external protection diodes for overvoltage?
No external protection diodes are required. Internal ESD clamps limit digital and analog pin voltages to (V−) −2V and (V+) +2V, and continuous current is limited to 30mA per terminal. The datasheet explicitly states that signals exceeding V+ or V− will be clamped by these internal diodes - a built-in feature confirmed in Absolute Maximum Ratings and Application Information sections.
How does the DG441DY-T handle bidirectional analog signals?
The DG441DY-T's SPST switches are fully bilateral: source (Sx) and drain (Dx) terminals are interchangeable with no performance penalty. Its rDS(ON) variation is low across ±5V analog input range, and OFF capacitance is symmetric (4pF each). This enables seamless use in transducer excitation, current-loop interfaces, and AC-coupled signal chains where signal direction may reverse dynamically.
Is the DG441DY-T RoHS compliant and lead-free?
Yes, the DG441DY-T is RoHS compliant and features Pb-free plus anneal construction: 100% matte tin termination, RoHS-compliant molding compound and die attach, and MSL classification meeting IPC/JEDEC J-STD-020 reflow standards. This is documented in the Ordering Information table and Notes section of the FN3281 datasheet, confirming full compliance for modern assembly processes.
