Product details
Overview
DG211BDY-T1-E3 from Vishay Siliconix is a quad, normally closed (NC), single-pole single-throw (SPST) CMOS analog switch in 16-pin narrow SOIC package, rated for ±22 V dual supply operation, with 50 Ω typical on-resistance, 120 ns turn-on time, and 1 pC charge injection - used in precision sample-and-hold circuits and digitally programmable filter/amplifier signal paths.
For engineers reviewing the DG211BDY-T1-E3 datasheet, DG211BDY-T1-E3 pinout, DG211BDY-T1-E3 application, or DG211BDY-T1-E3 equivalent, this page delivers verified electrical parameters, real-world timing behavior, bi-directional analog channel performance, RoHS-compliant packaging details, and validated alternative options for industrial instrumentation and test equipment design.
Technical Context
The DG211BDY-T1-E3 implements four independent NC analog switches fabricated in Vishay's silicon gate CMOS process, enabling true bi-directional signal flow with rail-to-rail analog voltage handling up to ±22 V and guaranteed 30 mA continuous current per channel. Its internal epitaxial layer prevents latch-up under transient overvoltage conditions.
Logic control uses TTL/CMOS-compatible inputs (VINH ≥ 2.4 V, VINL ≤ 0.8 V), referenced to VL = 5 V, while analog channels operate across V+ and V− rails independently of logic supply. Charge injection compensation minimizes switching transients critical for low-error sampling applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±4.5 V to ±22 V dual supply - supports wide analog input range without level-shifting circuitry |
| On-Resistance (rDS(on)) | 45 Ω (typ), 100 Ω (max) at ±15 V - ensures minimal signal attenuation and gain error in precision amplifiers |
| Turn-On Time (tON) | 120 ns (typ) - enables fast multiplexing in high-speed data acquisition systems |
| Charge Injection (Q) | 1 pC (typ) - reduces hold-mode voltage error in sample-and-hold circuits below 1 mV with 1 nF hold capacitor |
| Off-Leakage Current | ±0.01 nA (max) at ±14 V - preserves accuracy in high-impedance sensor interfaces and integrator nodes |
| Off Isolation (OIRR) | 90 dB at 100 kHz - suppresses crosstalk between adjacent switched channels in multi-channel instrumentation |
| Channel Capacitance (CD(on)) | 16 pF - maintains bandwidth integrity in RF-adjacent analog signal routing |
Pinout & Package
Package: 16-pin narrow SOIC (JEDEC MS-012), body width 3.9 mm, lead pitch 1.27 mm, RoHS-compliant matte tin finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 5, 12 | D1–D4 (Drain) | Analog output terminals - bi-directional, rated for ±22 V, 30 mA continuous |
| 2, 3, 6, 11 | S1–S4 (Source) | Analog input terminals - functionally interchangeable with drains in on-state |
| 7, 10 | V−, V+ | Analog supply rails - define full analog signal range; must be decoupled locally |
| 8 | GND | Digital ground reference - separate from analog ground but tied at system star point |
| 9 | VL | Logic supply input - accepts 5 V TTL/CMOS; isolates digital noise from analog section |
| 13–16 | IN1–IN4 | Active-low digital control inputs - logic "0" closes switch (NC), logic "1" opens it |
Key Features
| Feature | Design Value |
|---|---|
| Normally closed (NC) topology | Ensures fail-safe signal path continuity during power loss or logic reset in safety-critical monitoring systems |
| ±22 V analog rating | Eliminates external clamping diodes when interfacing with ±15 V op-amp stages or industrial sensors |
| 1 pC charge injection | Enables sub-12-bit accuracy in 1 MSPS sample-and-hold designs without post-correction calibration |
| 50 Ω on-resistance match (ΔrDS(on)) | Supports matched-gain switching in differential amplifier feedback networks and programmable gain arrays |
| Latch-up immunity | Guaranteed by epitaxial isolation - allows safe hot-swap operation in modular test equipment backplanes |
Applications
| Industrial Instrumentation | Test Equipment |
|---|---|
|
Use Scenario: Multiplexing thermocouple, RTD, and strain gauge signals into a shared 24-bit sigma-delta ADC front-end. IC Role / Device Role / Timing Role: Quad NC switch routes low-level analog inputs while maintaining DC continuity during channel scan transitions.

Use Scenario: Configuring programmable low-pass filter cutoff frequencies in automated benchtop signal analyzers. IC Role / Device Role / Timing Role: DG211BDY-T1-E3 selects discrete capacitor values in feedback paths of op-amp filters under microcontroller control. Use Value: 50 Ω rDS(on) adds negligible series resistance to RC time constants, ensuring ±0.5% corner frequency accuracy. |
| Sample-and-Hold Circuits | Precision Amplifier Gain Switching |
|
Use Scenario: High-fidelity acquisition stage in portable oscilloscopes requiring 1 µs aperture time and <5 mV sample-to-hold offset. IC Role / Device Role / Timing Role: DG211BDY-T1-E3 acts as the hold switch, closing only during acquisition phase to charge the hold capacitor. Use Value: 120 ns tON and 1 pC Q enable 25 µs total acquisition time with <1 LSB error at 16-bit resolution. |
Use Scenario: Digitally selecting gain factors (×1, ×10, ×100, ×1000) in a calibrated lab-grade differential amplifier. IC Role / Device Role / Timing Role: DG211BDY-T1-E3 configures feedback resistor networks while maintaining matched on-resistance across all gain settings. Use Value: ΔrDS(on) ≤ 2 Ω ensures gain error variation stays below 0.02% across all four gain states. |
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 NO switch; 60 Ω rDS(on); 2.5 V to 36 V single/dual supply; no VL pin | Requires redesign for NC functionality and logic/analog supply separation | Preferred where single-supply operation and lower cost outweigh NC requirement |
| ADG411BRZ | Quad SPST NO switch; 35 Ω rDS(on); ±15 V rating; 100 ns tON; no charge injection spec | Lacks NC configuration and specified charge injection - unsuitable for sample-and-hold | Selected when ultra-low on-resistance is prioritized over fail-safe closure and transient-free sampling |
Compared with DG211BDY-T1-E3, MAX4617ESE+ offers wider supply flexibility but requires circuit rework for NC behavior, while ADG411BRZ delivers lower rDS(on) yet lacks the guaranteed 1 pC charge injection and NC topology essential for precision hold-mode stability.

FAQ
What is the logic polarity of DG211BDY-T1-E3 control inputs?
The DG211BDY-T1-E3 features active-low logic control: a logic "0" (≤0.8 V) closes the normally closed switch, while a logic "1" (≥2.4 V) opens it. This behavior is confirmed in the truth table of Vishay document 70040 and applies directly to pins IN1–IN4 of DG211BDY-T1-E3. The device does not invert logic - its NC state is the default, de-energized condition.
Can DG211BDY-T1-E3 operate from a single +12 V supply?
Yes, DG211BDY-T1-E3 supports single-supply operation: V+ = +12 V, V− = 0 V, with analog signal range 0 V to +12 V. Per Vishay specification sheet 70040, the device maintains 90 Ω (max) rDS(on) and 300 ns tON under these conditions. However, VL must still be supplied at 5 V, and the logic interface remains TTL/CMOS compatible.
What is the maximum continuous current rating per channel of DG211BDY-T1-E3?
The DG211BDY-T1-E3 is rated for 30 mA continuous current per channel, as specified in the Absolute Maximum Ratings table of Vishay document 70040. This rating holds across the full operating temperature range (−40 °C to +85 °C) and applies to both source and drain terminals when the switch is on. Exceeding this limit risks thermal runaway or parametric shift.
Does DG211BDY-T1-E3 require external protection diodes for analog inputs exceeding V+ or V−?
No - DG211BDY-T1-E3 integrates internal clamping diodes on all analog terminals (Sx, Dx). As noted in footnote "a" of Vishay document 70040, signals exceeding V+ or V− are clamped, provided forward diode current is limited to the device's absolute maximum ratings (30 mA continuous, 100 mA pulsed). External diodes are unnecessary unless peak currents exceed those limits.
Is DG211BDY-T1-E3 pin-compatible with the legacy DG211DJ DIP package version?
No - DG211BDY-T1-E3 (16-pin narrow SOIC) is not pin-compatible with DG211DJ (16-pin plastic DIP). Although both share identical functional pin assignments (e.g., pin 1 = D1, pin 2 = S1), the SOIC package has different mechanical dimensions, lead pitch (1.27 mm vs. 2.54 mm), and thermal pad layout. PCB footprint and reflow profile must be redesigned for DG211BDY-T1-E3.
