Product details
Overview
DG417BDQ-T1-E3 from Vishay Siliconix is a precision monolithic single-pole single-throw (SPST) CMOS analog switch optimized for high-fidelity signal routing in low-power, battery-operated instrumentation. It delivers ±15 V analog signal range, 15 Ω typical on-resistance at ±15 V supplies, 110 ns turn-on time, and operates across –40 °C to +85 °C - enabling use in portable precision test equipment and military-grade guidance interfaces.
For engineers reviewing the DG417BDQ-T1-E3 datasheet, DG417BDQ-T1-E3 pinout, DG417BDQ-T1-E3 application, or DG417BDQ-T1-E3 equivalent, key selection criteria include guaranteed break-before-make timing (for DG419B only), leakage performance below 0.25 nA off-state, MSOP-8 footprint compatibility, and HVSG process–enabled latchup immunity in dual-supply configurations.
Technical Context
The DG417BDQ-T1-E3 implements a single SPST switch channel using Vishay's high-voltage silicon gate (HVSG) process, supporting symmetric ±15 V analog rail operation with bidirectional conduction and rail-to-rail blocking. Its control logic responds to TTL/CMOS-compatible inputs (0 V ≤ VIN(L) ≤ 0.8 V, 2.4 V ≤ VIN(H) ≤ VL), with internal level-shifting enabling robust switching under mixed-supply conditions.
Designed for precision analog signal integrity, it features 38 pC charge injection, –82 dB off-isolation at 1 MHz, and <12 pF off-capacitance - minimizing transient errors and crosstalk in sample-and-hold and multiplexed data acquisition systems where signal fidelity and settling time are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V - supports full-rail analog signals without clipping in dual-supply precision circuits |
| RDS(on) | 15 Ω typ. - ensures minimal voltage drop and signal distortion at ±15 V supply |
| tON | 110 ns max. - enables fast channel switching in time-critical sampling and sequencing applications |
| IS(off) | ±0.25 nA max. - guarantees ultra-low leakage for high-impedance sensor front-ends and long-hold intervals |
| Charge Injection | 38 pC - limits voltage glitch amplitude in sample-and-hold capacitors (e.g., 10 nF cap → ~3.8 mV step) |
| Off Isolation (OIRR) | –82 dB at 1 MHz - suppresses coupling between active and inactive channels in multi-channel systems |
| Supply Voltage Range | V+ = 20 V, V− = –20 V - provides 5 V headroom for transient protection and rail margining |
Pinout & Package
DG417BDQ-T1-E3 is housed in an 8-pin MSOP package (JEDEC MO-187, variation AA/BA), measuring 3.0 mm × 3.0 mm × 1.1 mm with 0.65 mm lead pitch. The exposed pad variant is not specified; thermal dissipation relies on PCB copper area under the body per Vishay's recommended layout guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (S) | Source terminal | Analog input/output node; bidirectional conduction path when switch is ON |
| 2 (D) | Drain terminal | Analog output/input node; electrically equivalent to S when ON; blocks up to V+/V− when OFF |
| 3 (V−) | Negative supply rail | Bias reference for analog channel; must be connected to system negative rail or ground |
| 4 (GND) | Digital ground reference | Return path for logic control current; separate from analog ground in mixed-signal layouts |
| 5 (IN) | Digital control input | Active-high logic: IN = HIGH → switch ON; compatible with 3.3 V/5 V CMOS/TTL drivers |
| 6 (V+) | Positive supply rail | Bias reference for analog channel; supports up to +20 V for transient margin |
| 7 (VL) | Logic supply voltage | Independent 2.7–5.5 V rail for control interface; decoupling required near pin |
| 8 (NC) | No connect | Internally unconnected; must remain floating - no external tie or pull-up/down |
Key Features
| Feature | Design Value |
|---|---|
| High-Voltage Silicon Gate (HVSG) Process | Enables ±15 V analog operation with latchup immunity via epitaxial isolation layer |
| Ultra-Low Off-Leakage | ≤ ±0.25 nA at ±15.5 V - preserves accuracy in high-Z sensor and integrator circuits |
| Low Charge Injection | 38 pC - reduces hold-step error in 12-bit+ sample-and-hold designs with ≥10 nF capacitors |
| TTL/CMOS-Compatible Control | Accepts 0.8 V / 2.4 V logic thresholds with <0.5 µA input current - simplifies microcontroller interfacing |
| Small MSOP-8 Footprint | 3.0 mm × 3.0 mm area - saves board space in portable and densely packed instrumentation modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617EUA+ | Higher RDS(on) (35 Ω typ.), lower supply voltage (±12 V max), same MSOP-8 package | Less suitable for ±15 V signal chains; better for cost-sensitive 3.3 V–5 V systems | Select if operating exclusively within 0–12 V unipolar or ±12 V bipolar rails and lower BOM cost is prioritized |
| ADG1419BRMZ | Lower RDS(on) (1.3 Ω typ.), higher supply rating (±16.5 V), larger 10-lead MSOP package | Requires PCB redesign due to different pinout and footprint; superior for ultra-low-distortion audio routing | Choose when sub-2 Ω on-resistance and <10 pC charge injection are mandatory, and layout revision is feasible |
Compared with MAX4617EUA+ and ADG1419BRMZ, DG417BDQ-T1-E3 offers the optimal balance of ±15 V capability, 15 Ω RDS(on), and compact MSOP-8 packaging for portable precision instruments where rail compliance and board space are jointly constrained.

FAQ
What is the maximum analog signal voltage range supported by DG417BDQ-T1-E3?
DG417BDQ-T1-E3 supports an analog signal range of ±15 V when operated with V+ = +15 V and V− = −15 V. This is guaranteed per the datasheet specification VANALOG = −15 V to +15 V under full temperature range (−40 °C to +85 °C). Exceeding these levels risks clamping by internal diodes and potential damage if forward current exceeds 30 mA.
Is DG417BDQ-T1-E3 pin-compatible with DG417BDY-T1-E3 or DG417BDJ-E3?
No, DG417BDQ-T1-E3 is not pin-compatible with DG417BDY-T1-E3 (SOIC-8) or DG417BDJ-E3 (MiniDIP). While all three share identical pin functions and logic behavior, the MSOP-8 package of DG417BDQ-T1-E3 has a 0.65 mm lead pitch and 3.0 mm × 3.0 mm body, whereas SOIC-8 uses 1.27 mm pitch and MiniDIP uses 2.54 mm pitch - requiring distinct PCB footprints and layout revisions.
Does DG417BDQ-T1-E3 feature break-before-make switching?
No, DG417BDQ-T1-E3 does not implement break-before-make (BBM) switching. BBM is guaranteed only for the DG419B SPDT variant per the datasheet. DG417B is a single-pole single-throw (SPST) switch with simple ON/OFF control; simultaneous conduction during transition is possible, making it unsuitable for power rail switching where shoot-through must be avoided.
What is the typical charge injection value for DG417BDQ-T1-E3, and how does it affect circuit design?
DG417BDQ-T1-E3 specifies 38 pC typical charge injection measured at the drain pin with CL = 10 nF. In sample-and-hold applications, this injects a voltage step ΔV = Q/C - e.g., 3.8 mV into a 10 nF hold capacitor. Designers must size the hold capacitor sufficiently large or add correction circuitry to keep this error within ADC LSB requirements for 12-bit+ systems.
Can DG417BDQ-T1-E3 operate with unipolar supplies such as V+ = 12 V and V− = 0 V?
Yes, DG417BDQ-T1-E3 supports unipolar operation with V+ = 12 V and V− = 0 V. In this configuration, the analog signal range is 0 V to 12 V, RDS(on) increases to 26 Ω typ., and tON rises to 100 ns. All logic interface requirements (VL, IN thresholds) remain unchanged, enabling flexible integration into mixed-supply systems.
