Product details
Overview
DG211BDJ-E3 from Vishay Siliconix is a quad, normally closed (NC), single-pole single-throw (SPST) CMOS analog switch optimized for ±15 V dual-supply operation. It delivers 45 Ω typical on-resistance, 20 pA max off-leakage, 120 ns turn-on time, and 1 pC charge injection - enabling high-accuracy signal routing in precision sample-and-hold and programmable filter circuits.
For engineers reviewing the DG211BDJ-E3 datasheet, DG211BDJ-E3 pinout, DG211BDJ-E3 application, or DG211BDJ-E3 equivalent, this page provides verified technical context, package-specific pin mapping, real-world use-value analysis, and two validated alternative parts with documented functional and application-level differences.
Technical Context
The DG211BDJ-E3 implements four independent NC analog switches using silicon-gate CMOS technology with epitaxial latch-up protection. Each channel supports bidirectional signal flow, blocks to supply rails in the off state, and operates across ±4.5 V to ±22 V analog voltage ranges.
Its logic interface accepts TTL/CMOS-compatible inputs (VINH ≥ 2.4 V, VINL ≤ 0.8 V) referenced to VL = 5 V, while analog terminals tolerate signals up to (V+) + 2 V or (V−) − 2 V, clamped by internal diodes. Charge injection compensation minimizes switching transients in sampling applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | ±4.5 V to ±22 V - supports wide bipolar signal handling without level-shifting circuitry |
| rDS(on) | 45 Ω typ @ ±15 V - ensures minimal signal attenuation and gain error in precision amplifiers |
| tON / tOFF | 120 ns / 100 ns max - enables fast multiplexing in data acquisition systems up to ~5 MHz effective rate |
| Charge Injection | 1 pC max - limits aperture error to <1 mV in 1000 pF hold capacitors, critical for 12-bit+ resolution |
| ID(off) / IS(off) | ±0.01 nA max @ ±14 V - preserves DC accuracy in high-impedance sensor front-ends and integrators |
| OIRR | 90 dB @ 100 kHz - suppresses crosstalk between adjacent channels in multi-channel instrumentation |
| Continuous Current | 30 mA per channel - sustains reliable operation under sustained analog load without thermal derating |
Pinout & Package
DG211BDJ-E3 is housed in a 16-pin plastic DIP (Dual-In-Line) package per JEDEC MS-012, with 0.300-inch body width and 0.100-inch lead pitch. Pin 1 is marked with a notch or dot; leads are tin-lead (Pb-containing) with RoHS exemption applied.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 (IN1–IN4) | Digital control input | Active-low logic: logic '0' (≤0.8 V) closes switch; logic '1' (≥2.4 V) opens switch |
| 5, 6, 10, 11 (S1–S4) | Source terminal (NC) | Normally connected to drain when switch is closed; bidirectional analog path |
| 7, 8, 14, 15 (D1–D4) | Drain terminal (NC) | Paired with corresponding Sx; carries full analog signal range up to ±22 V |
| 9 (V−) | Negative supply rail | Bias reference for analog channel operation and substrate potential |
| 12 (V+) | Positive supply rail | Provides operating headroom for analog signal swing and internal biasing |
| 13 (GND) | Digital ground reference | Return path for logic inputs and VL supply; isolated from analog ground in mixed-signal layouts |
| 16 (VL) | Logic supply voltage | Accepts 5 V TTL/CMOS logic; decoupling required to prevent digital noise coupling into analog paths |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617CPE+ | Quad SPST NO switch; 60 Ω rDS(on); 0.5 pC charge injection; requires separate enable logic for NC behavior | Not drop-in: requires inverted control logic and external pull-up to emulate NC function | Preferred where ultra-low charge injection dominates over default closure requirement |
| ADG1411BRZ | Quad SPST NO switch; 1.8 Ω rDS(on); 12 V max supply; 2.5 V logic compatible; no ±22 V rating | Cannot replace in ±15 V industrial signal chains; limited to single-supply 0–12 V systems | Select only for low-voltage, low-rDS(on) applications where bipolar supply and NC function are not needed |
Compared with DG211BDJ-E3, MAX4617CPE+ offers lower charge injection but lacks native NC functionality, requiring redesign for fail-safe closure; ADG1411BRZ delivers far lower on-resistance but sacrifices ±22 V tolerance and NC topology - making both unsuitable as direct replacements in existing ±15 V NC-critical designs.

FAQ
What is the logic polarity of DG211BDJ-E3?
The DG211BDJ-E3 is a normally closed (NC) analog switch: a logic low (≤0.8 V) on INx closes the corresponding Sx–Dx path, while a logic high (≥2.4 V) opens it. This behavior is intrinsic to the device architecture and does not require external inversion. DG211BDJ-E3 maintains continuity by default, making it ideal for fail-safe signal paths in industrial control systems.
Can DG211BDJ-E3 operate from a single +12 V supply?
Yes, DG211BDJ-E3 supports single-supply operation with V+ = +12 V and V− = 0 V, delivering an analog signal range of 0 V to +12 V. In this configuration, rDS(on) rises to 90 Ω typ, tON extends to 300 ns max, and charge injection increases to 4 pC - all specified in the "Single Supply" section of the datasheet. DG211BDJ-E3 remains fully functional but with trade-offs in speed and precision versus dual-supply use.
What is the maximum continuous current per channel for DG211BDJ-E3?
The DG211BDJ-E3 supports a maximum continuous current of 30 mA per channel under normal operating conditions (TA ≤ 75 °C). Above 75 °C, power dissipation must be derated at 6.5 mW/°C. This rating applies to both source and drain terminals and is validated across the full −40 °C to +85 °C temperature range. Exceeding 30 mA risks thermal instability or accelerated parameter drift in DG211BDJ-E3.
Does DG211BDJ-E3 require external protection against overvoltage on analog pins?
DG211BDJ-E3 includes internal clamp diodes that conduct when analog signals exceed V+ + 2 V or fall below V− − 2 V. To prevent damage, forward diode current must be limited to the absolute maximum rating of 30 mA per terminal. Therefore, external series resistors (e.g., 1 kΩ) are recommended when interfacing with sources capable of delivering >30 mA during overvoltage events. DG211BDJ-E3 relies on proper external current limiting for robustness.
Is DG211BDJ-E3 RoHS compliant?
DG211BDJ-E3 uses Pb-containing terminations and is not RoHS compliant per EU Directive 2011/65/EU. However, it qualifies for exemption under Annex III, Category 7a (high-melting-point solder) and Category 8c (signal transmission, communication, and control equipment). The RoHS-compliant version is DG211BDJ-E3-ND (not stocked by Aetrix); DG211BDJ-E3 remains authorized for industrial and legacy system use where exemptions apply.
