Product details
Overview
DG417BDY-T1-E3 from Vishay Siliconix is a precision monolithic SPST CMOS analog switch optimized for bidirectional signal routing in high-accuracy, low-power systems. It delivers ±15 V analog signal range, 15 Ω on-resistance (RDS(on)), 110 ns turn-on time (tON), and operates across –40 °C to +85 °C - enabling use in battery-powered instrumentation and precision test equipment.
For engineers reviewing the DG417BDY-T1-E3 datasheet, DG417BDY-T1-E3 pinout, DG417BDY-T1-E3 application, or DG417BDY-T1-E3 equivalent, key selection criteria include guaranteed break-before-make timing (in DG419B variants), low charge injection (38 pC), sub-0.25 nA off-leakage, RoHS-compliant SOIC-8 packaging, and compatibility with TTL/CMOS logic levels.
Technical Context
The DG417BDY-T1-E3 implements a single-pole, single-throw (SPST) switch topology using Vishay's high-voltage silicon gate (HVSG) process, enabling ±15 V rail-to-rail analog signal handling and latchup immunity via epitaxial isolation. Its control logic is active-high: logic "1" (≥2.4 V) disables conduction, while logic "0" (≤0.8 V) enables the switch.
It features symmetrical on-resistance (<15 Ω typ.) and bidirectional conduction when enabled, with off-isolation exceeding –82 dB at 1 MHz and channel crosstalk below –88 dB (DG419B). Switching performance is characterized under RL = 300 Ω / CL = 35 pF loads, with tON/tOFF specified at 62/53 ns (typ.) under ±15 V dual-supply conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V - supports full rail-to-rail signal switching without clipping in dual-supply systems. |
| RDS(on) | 15 Ω (typ.) - ensures minimal signal attenuation and distortion in precision analog paths. |
| tON / tOFF | 110 ns / 89 ns (max) - enables fast multiplexing in data acquisition and sampling circuits. |
| Off-Leakage (IS(off)) | ±0.25 nA (max) - preserves accuracy in high-impedance sensor interfaces and sample-and-hold stages. |
| Charge Injection | 38 pC - limits voltage glitch on sampled nodes, critical for ADC front-end integrity. |
| Off Isolation (OIRR) | –82 dB @ 1 MHz - suppresses crosstalk between adjacent channels in multi-channel systems. |
| Supply Voltage Range | V+ = 20 V max, V− = –20 V max - accommodates wide industrial and military supply rails. |
Pinout & Package
Package: 8-pin narrow SOIC (JEDEC MS-012), body dimensions 4.90 mm × 3.90 mm × 1.50 mm, RoHS-compliant matte tin lead finish.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Active-low digital control input; logic "0" (≤0.8 V) enables switch conduction. |
| 2 | S | Source terminal - bidirectional analog path; connects to signal source or load. |
| 3 | D | Drain terminal - bidirectional analog path; completes switched signal path with S. |
| 4 | V− | Negative supply rail - must be connected to system ground or negative bias for dual-supply operation. |
| 5 | GND | Digital ground reference - decouples logic and analog return paths to minimize noise coupling. |
| 6 | V+ | Positive supply rail - powers analog switch core; supports up to +20 V. |
| 7 | VL | Logic supply voltage - accepts 2.4 V to V+; defines logic threshold and drives internal level shifters. |
| 8 | No Connect | Internally unused; must remain floating - no external connection permitted. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional analog conduction | Enables flexible signal routing in both directions with matched RDS(on), eliminating polarity constraints in AC-coupled or differential designs. |
| Low charge injection (38 pC) | Minimizes voltage step errors at switch output during state transitions - essential for precision sample-and-hold and multiplexed ADC applications. |
| TTL/CMOS logic compatibility | Accepts standard 0 V / 5 V logic levels directly, eliminating need for level-shifting circuitry in microcontroller- or FPGA-driven systems. |
| Epitaxial latchup immunity | Guarantees robust operation under transient overvoltage or ESD events without destructive latchup - critical for field-deployed instrumentation. |
| ±15 V analog range | Supports full-swing signals in industrial sensor interfaces, audio line drivers, and military radio front-ends without external clamping diodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617EUA+ | Higher RDS(on) (35 Ω max), wider temp range (–40 °C to +125 °C), same SOIC-8 package. | Better suited for automotive under-hood environments; less optimal for ultra-low-distortion instrumentation. | Select MAX4617EUA+ only if extended temperature operation is required and higher on-resistance is acceptable. |
| ADG1419BRMZ | Lower RDS(on) (1.3 Ω typ.), higher supply voltage limit (+36 V), but higher charge injection (120 pC). | Preferred for high-current analog routing; unsuitable where low glitch energy is mandatory (e.g., precision S/H). | Choose ADG1419BRMZ for low-loss power signal switching; avoid in metrology-grade sampling paths due to elevated charge injection. |
Compared with DG417BDY-T1-E3, MAX4617EUA+ trades lower leakage and tighter RDS(on) tolerance for higher on-resistance, while ADG1419BRMZ sacrifices charge injection performance for drastically reduced conduction loss - making DG417BDY-T1-E3 the balanced choice for general-purpose precision analog switching.

FAQ
What is the maximum supply voltage rating for DG417BDY-T1-E3?
The DG417BDY-T1-E3 supports V+ up to +20 V and V− down to –20 V, with absolute maximum ratings defined per the Vishay datasheet (Document Number: 72107). Operation beyond these limits risks permanent damage. For reliable long-term use, design within the recommended operating range of ±15 V analog signal swing and ensure VL remains between (GND – 0.3 V) and (V+ + 0.3 V). The DG417BDY-T1-E3 must never be subjected to continuous voltages exceeding these absolute maxima.
Is DG417BDY-T1-E3 pin-compatible with DG418BDY-T1-E3?
Yes, DG417BDY-T1-E3 and DG418BDY-T1-E3 share identical SOIC-8 pinouts and package dimensions, but implement opposite logic polarity: DG417BDY-T1-E3 enables on logic "0", while DG418BDY-T1-E3 enables on logic "1". No PCB redesign is needed for substitution, but firmware or logic-level translation must be verified. Both devices maintain identical RDS(on), leakage, and timing specs - making them functionally interchangeable with only control-signal inversion required.
Does DG417BDY-T1-E3 support single-supply operation?
Yes, DG417BDY-T1-E3 supports single-supply operation with V+ = 12 V and V− = 0 V, delivering 0 V to 12 V analog signal range. In this configuration, RDS(on) increases to 26 Ω (typ.), tON extends to 100 ns (typ.), and leakage remains within ±0.25 nA (max). GND and V− must be tied together, and VL should be set to 5 V. The DG417BDY-T1-E3 maintains full functionality but with degraded dynamic performance versus dual-supply mode.
What is the thermal derating behavior of DG417BDY-T1-E3 in SOIC-8 package?
The DG417BDY-T1-E3 in SOIC-8 package has a power dissipation limit of 400 mW at ≤70 °C ambient. Above 70 °C, it must be derated at 4 mW/°C - meaning maximum allowable power drops to 360 mW at 80 °C and 320 mW at 90 °C. This derating applies regardless of whether power is consumed in analog conduction or logic drive. Thermal design must ensure junction temperature stays below 150 °C, with board layout providing adequate copper area for heat spreading.
How does DG417BDY-T1-E3 handle analog signals exceeding the supply rails?
DG417BDY-T1-E3 includes internal clamp diodes that limit analog signals on S or D pins to V+ + 2 V and V− – 2 V. If forward current exceeds 30 mA, permanent damage may occur. Therefore, external series resistors must be used to limit diode current when overvoltage transients are expected. The DG417BDY-T1-E3 is not fault-protected - sustained overvoltage requires external protection circuitry, such as TVS diodes or current-limiting resistors, to remain within safe operating area.
