Product details
Overview
DG417BDY-T1 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 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 portable instrumentation and military-grade sample-and-hold circuits.
For engineers reviewing the DG417BDY-T1 datasheet, DG417BDY-T1 pinout, DG417BDY-T1 application, or DG417BDY-T1 equivalent, this page provides verified functional identity, SOIC-8 package mapping, validated switching performance under dual-supply (±15 V) and single-supply (12 V) conditions, and confirmed alternative options for precision analog multiplexing and signal gating.
Technical Context
The DG417BDY-T1 implements a single SPST switch with break-before-make logic compatibility shared across the DG417B/DG418B family (though DG417B itself is non-break-before-make). Its HVSG (High-Voltage Silicon Gate) process enables ±20 V absolute maximum supply ratings and latchup immunity via epitaxial isolation.
It features bidirectional conduction when on, rail-to-rail analog blocking when off, TTL/CMOS-compatible digital control (logic "0" ≤ 0.8 V, "1" ≥ 2.4 V), and low charge injection (38 pC) critical for precision sampling. Input leakage remains below ±0.25 nA over full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V - supports full-rail bipolar signal switching without clipping in precision test equipment |
| RDS(on) | 15 Ω typical at ±15 V supplies - minimizes gain error and THD in buffered signal paths |
| tON/tOFF | 110 ns / 88 ns - enables sub-microsecond channel selection in automated test systems |
| Off-Leakage (IS(off)) | ±0.25 nA max at ±15.5 V - preserves accuracy in high-impedance sensor front-ends and integrators |
| Charge Injection | 38 pC - limits voltage step error in sample-and-hold amplifiers with 10 nF hold capacitors |
| Off Isolation (OIRR) | –82 dB at 1 MHz - suppresses crosstalk between adjacent channels in multi-channel data acquisition |
| Supply Range | V+ = 20 V, V− = –20 V - accommodates industrial ±15 V and automotive 12 V systems with margin |
Pinout & Package
DG417BDY-T1 is housed in an 8-pin narrow SOIC (SOIC-8) package per JEDEC MS-012, with 1.27 mm pitch, 4.9 mm × 3.9 mm body, and 1.75 mm max height. Pin 1 is marked by a beveled corner or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Digital control input | Active-high logic: switch closes when voltage ≥ 2.4 V (TTL/CMOS compatible) |
| 2 - S | Source terminal | Bidirectional analog port; connects to signal source or load depending on system topology |
| 3 - D | Drain terminal | Bidirectional analog port; complements S to form a fully symmetric switch path |
| 4 - V− | Negative supply rail | Supports dual-supply operation down to –20 V; required for ±15 V analog range |
| 5 - GND | Ground reference | Logic ground and substrate reference; must be tied to system common for noise control |
| 6 - V+ | Positive supply rail | Supports dual-supply up to +20 V or single-supply up to +12 V operation |
| 7 - VL | Logic supply | Independent 5 V rail for digital interface; decoupling required to prevent switching noise coupling |
| 8 - NC | No connect | Internally unconnected; must remain floating - no external tie or pull-up/pull-down |
Key Features
| Feature | Design Value |
|---|---|
| High-voltage silicon gate (HVSG) process | Enables ±20 V absolute max ratings and robust ESD tolerance without external protection |
| Rail-to-rail analog switching | Conducts equally well in both directions with full ±15 V signal swing - eliminates polarity constraints |
| Low 38 pC charge injection | Reduces settling error in 12-bit+ sample-and-hold circuits using 10 nF hold capacitors |
| Epitaxial latchup immunity | Guarantees no destructive latchup under transient overvoltage or hot-swap conditions |
| TTL/CMOS logic compatibility | Accepts standard 0 V / 5 V control signals without level-shifting - simplifies microcontroller interfacing |

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), no VL pin - integrated logic supply | Less suitable for ±15 V signal paths; better for space-constrained 3.3 V/5 V-only systems | Select MAX4617EUA+ only if board uses single 5 V rail and analog range ≤ ±10 V |
| ADG1419BRMZ | Lower RDS(on) (1.3 Ω), higher bandwidth (200 MHz), but higher leakage (±200 pA) and no VL separation | Preferred for high-speed multiplexing (>1 MSPS); unsuitable for ultra-low-leakage integrator applications | Choose ADG1419BRMZ when speed > precision; retain DG417BDY-T1 for sub-nA leakage-critical designs |
Compared with MAX4617EUA+ and ADG1419BRMZ, DG417BDY-T1 uniquely balances ±15 V analog range, sub-nA leakage, and isolated VL for noise-sensitive mixed-signal systems - making it optimal for portable precision measurement where supply separation and rail-to-rail fidelity are mandatory.

FAQ
What is the maximum analog signal voltage supported by DG417BDY-T1?
DG417BDY-T1 supports analog signals from V− to V+, with absolute maximum ratings of –20 V to +20 V. Under recommended operating conditions, it reliably switches ±15 V signals when powered with V+ = +15 V and V− = –15 V - confirmed in the datasheet's Analog Signal Range specification (VANALOG = ±15 V).
Does DG417BDY-T1 require separate logic and analog supplies?
Yes. DG417BDY-T1 has dedicated VL (pin 7) for logic interface and independent V+ (pin 6) and V− (pin 4) for analog rails. This separation prevents digital switching noise from coupling into sensitive analog paths - a key design feature validated in Vishay's Application Note 826 and SOIC-8 layout guidelines.
Is DG417BDY-T1 pin-compatible with DG417BDY or DG417BDY-E3?
Yes. DG417BDY-T1, DG417BDY, and DG417BDY-E3 share identical SOIC-8 footprints, pinout, and electrical specifications. The suffix "-T1" denotes tape-and-reel packaging for automated assembly; "-E3" indicates lead (Pb)-free terminations. All three are mechanically and functionally interchangeable.
What is the thermal derating behavior of DG417BDY-T1 above 75 °C?
DG417BDY-T1 derates linearly at 5.3 mW/°C above 75 °C in SOIC-8 packages, as specified in Absolute Maximum Ratings. At 100 °C ambient, its usable power dissipation drops to 400 mW − (25 °C × 5.3 mW/°C) = 267.5 mW - ensuring safe operation in sealed enclosures or high-temperature industrial environments.
Can DG417BDY-T1 be used in single-supply configurations?
Yes. DG417BDY-T1 operates with V− = 0 V and V+ = 12 V, supporting 0 V to 12 V analog signals. In this mode, RDS(on) rises to 26 Ω (typ), tON increases to 100 ns, and leakage remains within ±0.25 nA - all verified in the datasheet's single-supply specification table (V+ = 12 V, V− = 0 V).
