Product details
Overview
DG202BDJ-E3 from Vishay Siliconix is a quad single-pole single-throw (SPST) normally open analog switch IC designed for precision signal routing in bipolar ±15 V or single +12 V supply systems. It delivers 45 Ω on-resistance, 120 ns turn-on time, 1 pC charge injection, ±22 V analog signal range, and 20 pA leakage current - enabling high-fidelity switching in sample-and-hold circuits and programmable filter designs.
For engineers reviewing the DG202BDJ-E3 datasheet, DG202BDJ-E3 pinout, DG202BDJ-E3 application, or DG202BDJ-E3 equivalent, key selection criteria include verified bi-directional analog conduction, guaranteed 30 mA continuous channel current, RoHS-compliant TSSOP-16 packaging, and compatibility with TTL/CMOS logic levels across -40 °C to +85 °C operation.
Technical Context
The DG202BDJ-E3 implements four independent SPST switches using Vishay's proprietary silicon gate CMOS process, delivering improved RDS(on), lower leakage, and faster switching versus legacy DG202. Each channel supports true bi-directional signal flow when on and blocks signals beyond supply rails when off.
Its internal charge injection compensation minimizes transients during switching, while an epitaxial layer prevents latch-up. The device operates from dual ±4.5 V to ±22 V or single +4.5 V to +25 V supplies, with logic thresholds fixed at ≤0.8 V (low) and ≥2.4 V (high) for robust digital interface reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | ±4.5 V to ±22 V dual or +4.5 V to +25 V single - enables wide dynamic range signal handling without level-shifting |
| RDS(on) | 45 Ω typical at ±15 V - ensures minimal signal attenuation and voltage drop in precision analog paths |
| tON/tOFF | 120 ns / 65 ns typical - supports high-speed multiplexing up to ~5 MHz without significant timing skew |
| Charge Injection | 1 pC typical - reduces sampling error in precision sample-and-hold and data acquisition systems |
| Leakage Current | ±20 pA max at ±14 V - preserves DC accuracy in high-impedance sensor and instrumentation front-ends |
| Analog Signal Range | ±15 V full range at ±15 V supply - accommodates industrial-grade signal amplitudes without clipping |
| Logic Compatibility | TTL/CMOS with VINH ≥2.4 V, VINL ≤0.8 V - eliminates need for external level translators in mixed-signal systems |
Pinout & Package
DG202BDJ-E3 is housed in a 16-pin narrow SOIC package (JEDEC MS-012), measuring 9.9 mm × 3.9 mm × 1.5 mm, with 1.27 mm pitch and gull-wing leads suitable for automated PCB assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | Input (IN1–IN4) | Digital control inputs - active-high logic turns corresponding switch ON (normally open configuration) |
| 2, 6, 10, 14 | Source (S1–S4) | Analog input terminals - bidirectional conduction path when switch is ON |
| 3, 7, 11, 15 | Drain (D1–D4) | Analog output terminals - connected to Sx when INx = high; isolated otherwise |
| 4 | V+ | Positive supply rail - must be ≥+4.5 V for stable operation; supports up to +22 V |
| 8 | GND | Ground reference - common return for digital logic and analog signal paths |
| 12 | V- | Negative supply rail - required for bipolar operation; supports down to -22 V |
| 16 | NC | No connect - internally unconnected; must remain floating or grounded per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Bi-directional analog switching | True bidirectional conduction in ON state allows flexible signal routing in either direction without polarity constraints |
| Low glitch energy | 1 pC charge injection minimizes transient voltage spikes during switching - critical for low-error sampling |
| High voltage tolerance | ±22 V supply rating and ±15 V analog signal range support industrial and test equipment signal levels |
| Latch-up immunity | Epitaxial layer construction prevents destructive latch-up under overvoltage or ESD stress conditions |
| Extended temperature operation | Rated for -40 °C to +85 °C ambient - validated for use in industrial embedded and portable instrumentation |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | Single-supply only (+2.7 V to +12 V); 60 Ω RDS(on); 25 pA leakage; SOIC-16 | Limited to unipolar systems; higher leakage affects DC-coupled precision use | Select when cost-sensitive unipolar applications dominate and ±15 V signal range is unnecessary |
| ADG1419BRUZ | Quad SPST; ±15 V supply; 1.3 Ω RDS(on); 1 nA leakage; TSSOP-16 | Lower on-resistance but higher leakage; requires tighter layout for thermal stability | Choose for ultra-low distortion audio or high-current analog paths where 45 Ω is insufficient |
Compared with MAX4617ESE+ and ADG1419BRUZ, DG202BDJ-E3 uniquely balances ±22 V operation, 45 Ω on-resistance, and 20 pA leakage in a mature, production-proven SOIC package - making it optimal for industrial instrumentation requiring both wide voltage range and DC precision.

FAQ
What is the maximum analog signal voltage supported by DG202BDJ-E3?
DG202BDJ-E3 supports analog signals up to ±15 V when operated from ±15 V supplies, and maintains full functionality across its rated supply range of ±4.5 V to ±22 V. Signals exceeding V+ or V− are clamped by internal diodes, with forward current limited to absolute maximum ratings - confirming its suitability for industrial-grade signal conditioning where ±12 V or ±15 V rails are standard.
Is DG202BDJ-E3 pin-compatible with the older DG202 or DG202A?
Yes, DG202BDJ-E3 is a direct replacement for DG202 and DG202A in 16-pin SOIC packages, retaining identical pinout, electrical specifications, and functional behavior. The "B" suffix denotes process and performance improvements including lower RDS(on), reduced leakage, and faster switching - all implemented without altering mechanical or logical interface compatibility.
Can DG202BDJ-E3 operate from a single +12 V supply?
Yes, DG202BDJ-E3 supports single-supply operation from +4.5 V to +25 V. At +12 V, it delivers 90 Ω typical RDS(on), 120 ns tON, and maintains full analog signal range from 0 V to +12 V - enabling simplified power architecture in portable instruments and embedded controllers where dual-rail supplies are impractical.
What is the thermal derating behavior of DG202BDJ-E3 above 75 °C?
DG202BDJ-E3 has a thermal derating factor of 7.6 mW/°C above 75 °C for its 16-pin narrow SOIC package. With a maximum power dissipation of 640 mW at 75 °C, this means usable power drops linearly to ~560 mW at 85 °C - a critical parameter for sustained operation in enclosed industrial enclosures or high-density PCB layouts where ambient temperature exceeds 75 °C.
Does DG202BDJ-E3 require external pull-up or pull-down resistors on its digital inputs?
No, DG202BDJ-E3 does not require external biasing on its digital inputs. Its TTL/CMOS-compatible logic thresholds (VINH ≥2.4 V, VINL ≤0.8 V) and low input current (<±1 µA) allow direct connection to microcontroller GPIOs, FPGA outputs, or logic gates without additional components - simplifying design and reducing bill-of-materials count in space-constrained applications.
