Product details
Overview
DG211BDY-E3 from Vishay Siliconix is a quad, normally closed (NC), single-pole single-throw (SPST) CMOS analog switch optimized for precision signal routing in ±15 V dual-supply systems. It delivers 45 Ω typical on-resistance, 20 pA max off-leakage at ±14 V, 120 ns turn-on time, ±22 V supply rating, and 1 pC charge injection - enabling high-fidelity sample-and-hold and low-distortion multiplexing in test equipment and instrumentation.
For engineers reviewing the DG211BDY-E3 datasheet, DG211BDY-E3 pinout, DG211BDY-E3 application, or DG211BDY-E3 equivalent, key selection criteria include its NC logic behavior, bi-directional analog signal handling up to ±15 V, TSSOP-16 package footprint, and compatibility with TTL/CMOS control levels - critical for maintaining signal integrity in automated test and data acquisition systems.
Technical Context
The DG211BDY-E3 implements four independent NC analog switches using silicon-gate CMOS technology, with epitaxial layer latch-up protection and internal clamping diodes limiting analog inputs to V+ ±2 V. Its charge-injection-compensated architecture minimizes switching transients during sampling.
Each channel operates bidirectionally with true off-isolation to supply rails, supports single-supply (up to +25 V) or dual-supply (±22 V) operation, and maintains rDS(on) matching ≤2 Ω across channels - essential for matched gain/attenuation paths in programmable filter and amplifier designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V (full rail-to-rail operation with ±15 V supplies; enables unclipped signal handling in industrial instrumentation) |
| Drain-Source On-Resistance | 45 Ω typ (low insertion loss; preserves amplitude accuracy in precision measurement front-ends) |
| Off-Leakage Current | ±0.01 nA max at ±14 V (sub-picoampere leakage prevents voltage droop in high-impedance sample-and-hold capacitors) |
| Turn-On Time | 120 ns (supports >1 MHz sampling rates in automated test equipment) |
| Charge Injection | 1 pC (minimizes hold-mode voltage error in precision S/H circuits; <5 mV offset with 1 nF capacitor) |
| Off Isolation | 90 dB at 100 kHz (prevents crosstalk between adjacent channels in multi-channel data loggers) |
| Supply Voltage Range | ±4.5 V to ±22 V (supports wide dynamic range signal conditioning without level-shifting) |
Pinout & Package
Package: 16-lead TSSOP (JEDEC MO-153, 5.0 mm × 4.4 mm × 1.2 mm), RoHS-compliant, Pb-free terminations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 (IN1–IN4) | Digital control input | TTL/CMOS-compatible logic; "0" = ON (closed) for DG211B; drives internal gate bias |
| 2, 5, 11, 14 (S1–S4) | Source terminal | Analog input/output node; bidirectional; connects to signal source in S/H or filter applications |
| 3, 6, 12, 15 (D1–D4) | Drain terminal | Analog input/output node; bidirectional; connects to load, op-amp input, or capacitor in precision circuits |
| 7 (V−) | Negative supply rail | Bias reference for analog path; must be connected to system negative rail (e.g., −15 V) |
| 8 (GND) | Digital ground | Logic reference; isolated from analog ground in mixed-signal layouts to reduce noise coupling |
| 9 (VL) | Logic supply | Accepts 5 V TTL/CMOS logic; decoupled separately from V+/V− to prevent digital switching noise injection |
| 16 (V+) | Positive supply rail | Bias reference for analog path; must be connected to system positive rail (e.g., +15 V) |
Key Features
| Feature | Design Value |
|---|---|
| Normally closed (NC) topology | Ensures fail-safe signal continuity during power loss or logic fault - critical in safety-monitored instrumentation |
| Epitaxial latch-up protection | Guarantees immunity to destructive latch-up under transient overvoltage or ESD events in industrial environments |
| Bi-directional analog conduction | Enables flexible signal routing (e.g., shared ADC input or DAC output) without polarity constraints |

Use Scenario: Routing RF IF signals or baseband audio/data streams between transceiver ICs and antenna switches or codec interfaces in multi-band radios. IC Role / Device Role / Timing Role: DG211BDY-E3 functions as a low-distortion analog switch in signal path selection, handling DC–100 kHz band-limited waveforms. Use Value: 120 ns switching time allows <1 µs channel reconfiguration; ±22 V rating accommodates headroom for envelope detection or AGC control voltages. |
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); 0.5 pC charge injection; ±20 V rating | Requires active-high logic for closure; lacks NC default state | Select when normally open behavior and lower charge injection are prioritized over fail-safe continuity |
| ADG1411BRUZ | Quad SPST NO switch; 1.8 Ω rDS(on); 0.2 pC charge injection; ±15 V rating; higher supply current | Superior on-resistance but limited to ±15 V; requires separate logic supply | Select for ultra-low distortion in audio or high-speed DAQ where NC functionality is not required |
Compared with MAX4617ESE+ and ADG1411BRUZ, DG211BDY-E3 uniquely provides normally closed operation with ±22 V tolerance and industry-proven latch-up immunity - making it preferred for industrial S/H, programmable filters, and safety-critical signal routing where default continuity and ruggedness outweigh marginal on-resistance gains.

FAQ
What is the logic behavior of DG211BDY-E3?
DG211BDY-E3 is a normally closed (NC) analog switch: logic low (≤0.8 V) on INx pins closes the switch (Sx–Dx path conductive), while logic high (≥2.4 V) opens it. This fail-safe behavior ensures signal continuity during power loss or controller reset - a key requirement in industrial S/H and safety-critical routing applications where uninterrupted analog path integrity is mandatory.
Does DG211BDY-E3 support single-supply operation?
Yes, DG211BDY-E3 supports single-supply operation from +4.5 V to +25 V (V− tied to GND). In this configuration, the analog signal range is 0 V to V+, e.g., 0–12 V with +12 V supply. The device maintains 90 Ω max rDS(on) and 4 pC max charge injection under single-supply conditions - validated per the "SPECIFICATIONS for Single Supply" table in Vishay Document 70040.
What is the maximum continuous current per channel for DG211BDY-E3?
The maximum continuous current per channel is 30 mA, as specified in the Absolute Maximum Ratings table. This rating applies across the full operating temperature range (−40 °C to +85 °C) and is derated linearly above +75 °C at 7.6 mW/°C. Exceeding this current risks thermal overstress and accelerated parameter drift, particularly in high-temperature industrial enclosures.
How does DG211BDY-E3 achieve low charge injection?
DG211BDY-E3 uses an improved charge injection compensation design in its silicon-gate CMOS process, balancing gate-to-drain/source capacitance asymmetries. This results in 1 pC typical charge injection (measured with CL = 1000 pF, Vgen = 0 V), directly reducing voltage step errors in sample-and-hold circuits - a critical spec confirmed in Figure 5 and Table "Dynamic Characteristics" of the DG211B/DG212B datasheet.
Is DG211BDY-E3 pin-compatible with the legacy DG211 series?
Yes, DG211BDY-E3 is pin-compatible with the original DG211 (e.g., DG211DJ, DG211DY) in all packages - including TSSOP-16. It retains identical pinout, electrical interface, and mechanical footprint while delivering improved specs: lower rDS(on), lower leakage, faster switching, and enhanced latch-up immunity - enabling drop-in replacement in existing designs without PCB or firmware changes.
