Product details
Overview
DG419BDY-T1-E3 from Vishay Siliconix is a precision monolithic SPDT CMOS analog switch designed for high-fidelity signal routing in dual-supply systems. It features ±15 V analog signal range, 15 Ω typical on-resistance, 110 ns turn-on time, break-before-make switching action, and operates over –40 °C to +85 °C - ideal for precision instrumentation and battery-powered test equipment.
For engineers reviewing the DG419BDY-T1-E3 datasheet, DG419BDY-T1-E3 pinout, DG419BDY-T1-E3 application, or DG419BDY-T1-E3 equivalent, key selection criteria include guaranteed break-before-make timing (tD = 16 ns typ), low charge injection (38 pC), sub-100 ns switching performance, and SOIC-8 package compatibility with standard PCB footprints.
Technical Context
The DG419BDY-T1-E3 implements a single-pole double-throw (SPDT) topology with two complementary switches (SW1 and SW2) controlled by one digital input. Its HVSG process enables ±15 V analog rail operation while maintaining low leakage (< ±0.75 nA off-state) and latchup immunity via epitaxial isolation.
Break-before-make timing is guaranteed by internal logic design and verified across temperature (–40 °C to +85 °C); transition time (tTRANS) is 60 ns typ at ±10 V signals with 300 Ω/35 pF load, and off-isolation exceeds –82 dB at 1 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V - supports full-rail bipolar signal switching without clipping in dual-supply precision systems |
| RDS(on) | 15 Ω typ - minimizes signal attenuation and gain error in low-impedance sensor or DAC output paths |
| tON/tOFF | 110 ns / 99 ns max - enables sub-microsecond channel selection for multiplexed data acquisition |
| Break-Before-Make Delay (tD) | 16 ns typ - prevents momentary shorting between S1 and S2, critical for fault-tolerant signal routing |
| Charge Injection | 38 pC - limits voltage glitch on high-impedance nodes (e.g., sample-and-hold capacitors) |
| Off Isolation (OIRR) | –82 dB at 1 MHz - suppresses crosstalk between active and inactive channels in dense analog layouts |
| Supply Current (I+, I–, IL) | < 1 µA max - enables ultra-low-power operation in portable and remote sensing applications |
Pinout & Package
Package: 8-pin narrow SOIC (SOIC-8, JEDEC MS-012), body dimensions 4.90 mm × 3.90 mm × 1.45 mm, lead pitch 1.27 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Digital control input | Active-high logic: IN = ≥2.4 V selects SW1 ON / SW2 OFF; IN = ≤0.8 V selects SW1 OFF / SW2 ON |
| 2 (S1) | SPDT common source 1 | First switch source terminal - bidirectional conduction path when SW1 is enabled |
| 3 (D) | SPDT common drain | Shared output node - connects to either S1 or S2 depending on IN state |
| 4 (S2) | SPDT common source 2 | Second switch source terminal - bidirectional conduction path when SW2 is enabled |
| 5 (V–) | Negative supply rail | Bias reference for analog channel - must be ≥ –20 V; clamps analog inputs below V– – 2 V |
| 6 (GND) | Digital ground reference | Logic return path; isolated from analog ground but tied to same potential in most designs |
| 7 (V+) | Positive supply rail | Bias reference for analog channel - must be ≤ +20 V; clamps analog inputs above V+ + 2 V |
| 8 (VL) | Logic supply voltage | Accepts 5 V TTL/CMOS levels; independent of V+/V– rails - enables mixed-voltage system interfacing |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed break-before-make | Ensures no overlap conduction between S1 and S2 - eliminates signal shorting during switching transients |
| Low on-resistance flatness | ≤25 Ω max over ±12.5 V signal swing - preserves linearity in audio and instrumentation amplifier interfaces |
| TTL/CMOS-compatible control | VL = 5 V logic interface with < ±0.5 µA input current - simplifies microcontroller or FPGA direct drive |
| High off-isolation & low crosstalk | OIRR > –82 dB and XTALK > –88 dB at 1 MHz - maintains channel separation in multi-channel DAQ systems |
| RoHS-compliant packaging | Lead-free terminations per Directive 2002/95/EC - meets environmental compliance for industrial and medical deployments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4619ESE+ | Higher RDS(on) (35 Ω typ), wider temp range (–40 °C to +125 °C), same SOIC-8 package | Better suited for automotive under-hood use; less suitable for low-distortion audio due to higher on-resistance | Select when extended temperature operation is required and 35 Ω on-resistance is acceptable |
| ADG1419BRMZ | Lower RDS(on) (2.6 Ω typ), higher supply voltage limit (+36 V), requires separate logic supply | Enables higher-voltage industrial signal conditioning; needs additional 3.3 V/5 V logic rail not needed by DG419BDY-T1-E3 | Select when ultra-low on-resistance or >±15 V analog range is mandatory, accepting added supply complexity |
Compared with MAX4619ESE+ and ADG1419BRMZ, the DG419BDY-T1-E3 delivers optimal balance of low distortion (15 Ω), guaranteed break-before-make, and single 5 V logic compatibility - making it preferred for portable precision instruments where board space, power, and signal integrity are jointly constrained.

FAQ
What is the guaranteed break-before-make timing specification for DG419BDY-T1-E3?
The DG419BDY-T1-E3 guarantees a break-before-make time delay (tD) of 16 ns typical at room temperature, with full characterization across –40 °C to +85 °C. This parameter is ensured by internal logic design and process control-not just typical behavior-and prevents simultaneous conduction between S1 and S2. The DG419BDY-T1-E3 datasheet specifies this value under RL = 300 Ω and CL = 35 pF conditions with ±10 V analog signals.
Does DG419BDY-T1-E3 support single-supply operation?
Yes, the DG419BDY-T1-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) increases to 26 Ω typical, tON extends to 100 ns typical, and leakage remains within spec. The DG419BDY-T1-E3 maintains full functionality including break-before-make and TTL/CMOS compatibility with VL = 5 V.
What is the maximum allowable analog input voltage beyond the supply rails for DG419BDY-T1-E3?
The DG419BDY-T1-E3 allows analog signals to exceed V+ or V– by up to 2 V, limited by internal clamp diodes. Specifically, any signal on S1, S2, or D pins may range from (V– – 2 V) to (V+ + 2 V), provided forward diode current stays below absolute maximum ratings (30 mA continuous). Exceeding these clamping limits risks permanent damage, as stated in the DG419BDY-T1-E3 Absolute Maximum Ratings table.
Is DG419BDY-T1-E3 pin-compatible with earlier DG419 variants like DG419DY?
Yes, the DG419BDY-T1-E3 is pin-compatible with all SOIC-8 variants in the DG419B family, including DG419DY and DG419DY-E3. The "-T1-E3" suffix denotes tape-and-reel packaging and lead-free termination, but electrical characteristics, pinout, and thermal profile remain identical to non-T1 versions. No PCB layout changes are required when upgrading to DG419BDY-T1-E3.
How does charge injection of DG419BDY-T1-E3 affect sample-and-hold accuracy?
The DG419BDY-T1-E3 exhibits 38 pC typical charge injection measured at the drain pin with CL = 10 nF. When used in a sample-and-hold circuit with a 10 nF hold capacitor, this injects a worst-case voltage glitch of 3.8 mV (Q/C), which corresponds to < 1 LSB error in a 12-bit system with 5 V full-scale range. The DG419BDY-T1-E3 datasheet confirms this value is characterized across ±15 V analog voltages and is stable over temperature.
