Product details
Overview
DG441LEDQ-T1-GE3 from Vishay Siliconix is a quad SPST analog switch with normally closed (NC) configuration, designed for precision signal routing in data acquisition and sample-and-hold circuits. It delivers 16 Ω typical on-resistance, 18 ns typical turn-on time, <10 pA typical leakage, and operates from +3 V to +16 V single supply or ±3 V to ±8 V dual supply - enabling use in medical instrumentation and battery-powered test equipment.
For engineers reviewing the DG441LEDQ-T1-GE3 datasheet, DG441LEDQ-T1-GE3 pinout, DG441LEDQ-T1-GE3 application, or DG441LEDQ-T1-GE3 equivalent, key selection criteria include NC logic behavior, low charge injection (<8 pC), TSSOP-16 package compatibility, and guaranteed -40 °C to +85 °C operation per D-suffix qualification.
Technical Context
The DG441LEDQ-T1-GE3 implements four independent bidirectional analog switches with complementary CMOS/TTL-compatible control inputs and internal level-shifting circuitry. Each channel features matched RDS(on) (≤0.5 Ω max mismatch), symmetrical conduction in both directions when on, and rail-to-rail analog signal handling up to supply limits.
Its architecture minimizes switching transients via low parasitic capacitance (CD(ON) = 15 pF, CS(OFF) = 5 pF) and tightly controlled charge injection (6.6 pC typ.), making it suitable for high-fidelity sampling where glitch energy and settling error must be constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RDS(on)) | 16 Ω typical at +12 V single supply - ensures minimal signal attenuation and gain error in precision amplifier front-ends. |
| Turn-on time (tON) | 18 ns typical at +12 V - supports sampling rates up to ~30 MHz in high-speed data acquisition systems. |
| Charge injection | 6.6 pC typical - limits voltage step error in sample-and-hold capacitors, critical for 12-bit+ ADC accuracy. |
| Analog signal range | 0 V to +12 V (single supply) or ±5 V (dual supply) - enables full-rail signal switching without clipping. |
| Leakage current (IS(off)) | <1 nA maximum at +25 °C - preserves long hold-time integrity in ultra-low-power metering applications. |
| Off isolation (OIRR) | 68.4 dB at 1 MHz - suppresses crosstalk between adjacent channels in multi-channel sensor multiplexing. |
| Supply voltage range | +3 V to +16 V single or ±3 V to ±8 V dual - supports flexible power architecture across portable and industrial designs. |
Pinout & Package
Package: 16-pin TSSOP (JEDEC MS-012, body dimensions 5.00 × 4.40 × 1.20 mm, lead pitch 0.65 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 | Digital control input (active-low for NC function) | Logic "0" ≤ 0.8 V turns corresponding switch ON; "1" ≥ 2.4 V turns it OFF - direct interface with microcontroller GPIOs. |
| S1–S4 | Source terminal (analog input) | Bidirectional analog node - connects to signal source (e.g., sensor output or DAC) with no polarity restriction. |
| D1–D4 | Drain terminal (analog output) | Bidirectional analog node - routes switched signal to ADC input or amplifier stage with matched impedance. |
| V+ | Positive supply rail | Accepts +3 V to +16 V (single) or +3 V to +8 V (dual) - powers internal switch core and level shifter. |
| V− | Negative supply rail | Accepts 0 V (single) or −3 V to −8 V (dual) - enables true bipolar signal handling and reduces distortion. |
| GND | Ground reference | Common return for digital logic and analog substrate - requires low-impedance PCB connection to minimize noise coupling. |
| NC (Pin 9) | No-connect terminal | Internally unconnected - must remain floating; not usable as thermal pad or ground tie. |
Key Features
| Feature | Design Value |
|---|---|
| Normally closed (NC) topology | Ensures fail-safe signal path continuity during power loss or control failure - critical in safety-critical monitoring circuits. |
| Low on-resistance match (ΔRDS(on) ≤ 0.5 Ω) | Minimizes gain mismatch across channels in programmable-gain amplifiers and multi-sensor calibration systems. |
| TTL/CMOS-compatible inputs | Eliminates need for external level shifters when interfacing with 3.3 V or 5 V microcontrollers and FPGAs. |
| Rail-to-rail analog switching | Supports full dynamic range utilization of 12-bit and higher-resolution ADCs without signal compression. |
| ESD robustness (2500 V HBM) | Reduces risk of field failure during handling and assembly - meets industrial-grade reliability requirements. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | NO configuration only; 35 Ω RDS(on); 25 ns tON; SOIC-16 only | Lacks NC functionality - requires external pull-down for default-on behavior | Select when NO logic suffices and SOIC footprint is preferred over TSSOP. |
| ADG1412YRUZ | NC/NO configurable per channel; 1.8 Ω RDS(on); 125 ns tON; ±15 V rating | Higher on-resistance match (0.2 Ω), but slower switching - better for DC-precision, worse for >1 MHz sampling | Choose for ultra-low distortion in audio or precision DC measurement where speed is secondary. |
Compared with MAX4617ESE+ and ADG1412YRUZ, the DG441LEDQ-T1-GE3 uniquely balances NC fail-safe operation, 16 Ω on-resistance, and 18 ns speed in a compact TSSOP-16 package - making it optimal for space-constrained, medium-speed instrumentation requiring inherent signal continuity.

FAQ
What is the logic behavior of DG441LEDQ-T1-GE3?
The DG441LEDQ-T1-GE3 is a normally closed (NC) quad SPST switch: a logic low (≤0.8 V) on IN1–IN4 turns the corresponding switch ON, while a logic high (≥2.4 V) turns it OFF. This fail-safe behavior ensures analog continuity during power loss or controller reset - a key requirement in medical and safety-critical systems where uninterrupted signal path is mandatory. DG441LEDQ-T1-GE3 maintains this NC function across its full operating temperature range (-40 °C to +85 °C).
Can DG441LEDQ-T1-GE3 operate from a single 3.3 V supply?
Yes, DG441LEDQ-T1-GE3 supports single-supply operation from +3 V to +16 V, including 3.3 V. At +3.3 V, RDS(on) increases to 71 Ω (typ.) and tON rises to 141 ns (typ.), but leakage remains <1 nA and charge injection drops to 2 pC - making it viable for low-power, low-speed applications like sensor polling in IoT edge nodes. DG441LEDQ-T1-GE3 retains full functionality and specified timing margins within this range.
How does DG441LEDQ-T1-GE3 handle analog signals exceeding supply rails?
DG441LEDQ-T1-GE3 includes internal clamping diodes that limit analog signals on Sx or Dx pins to V+ + 0.3 V and V− − 0.3 V. Exceeding these levels risks forward-biasing the diodes and exceeding the 30 mA absolute maximum continuous current rating. To protect the device, external series resistors must limit diode current - for example, a 1 kΩ resistor limits fault current to <10 mA if VANALOG reaches +20 V with V+ = +12 V. DG441LEDQ-T1-GE3 is not rated for overvoltage tolerance beyond its absolute maximum ratings.
What is the thermal derating for DG441LEDQ-T1-GE3 in TSSOP-16 package?
In its 16-pin TSSOP package, DG441LEDQ-T1-GE3 has a power dissipation limit of 450 mW at +25 °C, derating linearly by 7 mW/°C above +75 °C. At +105 °C ambient, maximum allowable power drops to 450 mW − (30 °C × 7 mW/°C) = 240 mW. This derating applies regardless of supply configuration (single or dual). DG441LEDQ-T1-GE3 thermal performance assumes standard JEDEC 2-layer board layout with recommended minimum pads per Vishay document 63550.
Is DG441LEDQ-T1-GE3 RoHS-compliant and lead-free?
Yes, DG441LEDQ-T1-GE3 is RoHS-compliant and lead-free, as indicated by the "-GE3" suffix per Vishay's material categorization standard (document 99912). The device uses matte tin (Sn) termination finish and conforms to EU Directive 2011/65/EU. No exemptions apply, and all homogeneous materials meet the 0.1 wt% threshold for restricted substances. DG441LEDQ-T1-GE3 is qualified for lead-free reflow soldering per JEDEC J-STD-020.
