Product details
Overview
DG419BDJ-E3 from Vishay Siliconix is a precision monolithic SPDT CMOS analog switch designed for high-performance signal routing in dual-supply systems. It features ±15 V analog signal range, 15 Ω on-resistance, 110 ns turn-on time, break-before-make switching, and operates over –40 °C to +85 °C - ideal for precision instrumentation and battery-powered test equipment.
For engineers reviewing the DG419BDJ-E3 datasheet, DG419BDJ-E3 pinout, DG419BDJ-E3 application, or DG419BDJ-E3 equivalent, this page delivers verified electrical specs, SOIC-8 package details, functional truth table, real-world use cases in military radios and sample-and-hold circuits, and two validated alternative parts with documented technical differences.
Technical Context
The DG419BDJ-E3 implements a single-pole double-throw (SPDT) topology with guaranteed break-before-make timing (tD = 16 ns typical), preventing signal shorting during state transitions. Its HVSG process enables ±20 V absolute maximum supply ratings and latchup immunity via epitaxial isolation.
It supports dual-supply operation (V+ = +15 V, V− = −15 V) and TTL/CMOS-compatible digital control (VIN low ≤ 0.8 V, high ≥ 2.4 V), with symmetrical bidirectional conduction and rail-to-rail analog signal blocking when off.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V - supports full-range bipolar signal switching without clipping in precision measurement paths |
| On-Resistance (RDS(on)) | 15 Ω typical - minimizes voltage drop and gain error in low-level analog signal paths |
| Turn-On Time (tON) | 110 ns max - enables fast multiplexing in data acquisition systems up to ~1 MHz effective rate |
| Break-Before-Make Delay (tD) | 16 ns typical - ensures no transient short between S1 and S2, critical for signal integrity in guidance systems |
| Off Isolation (OIRR) | –82 dB at 1 MHz - suppresses crosstalk between channels in multi-signal test fixtures |
| Charge Injection | 38 pC - limits voltage glitch in sample-and-hold amplifiers, reducing settling error |
| Supply Current (I+, I−) | 1 µA max - enables ultra-low-power operation in portable instrumentation with extended battery life |
Pinout & Package
DG419BDJ-E3 is housed in an 8-pin narrow SOIC (SOIC-8) package per JEDEC MS-012, with 1.27 mm pitch, 4.90 mm × 3.90 mm body, and 1.75 mm max height - compatible with standard automated PCB assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Digital control input | Active-high logic: '1' (≥2.4 V) connects S1 to D; '0' (≤0.8 V) connects S2 to D |
| 2 (S1) | SPDT source terminal 1 | First analog input path; bidirectional conduction when selected |
| 3 (S2) | SPDT source terminal 2 | Second analog input path; electrically isolated from S1 when unselected |
| 4 (V−) | Negative supply rail | Bias reference for analog channel; must be connected to system ground or negative rail |
| 5 (GND) | Logic ground | Reference for digital control inputs; tied to V− in dual-supply mode or system GND in single-supply |
| 6 (V+) | Positive supply rail | Bias reference for analog channel; supports up to +20 V absolute max |
| 7 (VL) | Logic supply voltage | Independent 5 V logic rail; decouples digital switching noise from analog section |
| 8 (D) | SPDT drain/common output | Single analog output node; routes either S1 or S2 based on IN state |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed 16 ns minimum delay prevents momentary short between S1 and S2 - essential for fault-tolerant signal routing |
| Rail-to-rail analog capability | ±15 V signal range with full on/off blocking up to supply rails - preserves dynamic range in precision ADC front-ends |
| Low charge injection (38 pC) | Minimizes hold-step error in sample-and-hold circuits, enabling <16-bit accuracy without additional correction |
| High off-isolation (–82 dB) | Reduces signal coupling between channels in multi-channel test equipment, improving measurement fidelity |
| HVSG process technology | Enables 20 V absolute max supply rating and latchup immunity - suitable for harsh industrial and military environments |

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), no guaranteed break-before-make, 12 V max supply | Limited to lower-voltage, lower-precision systems; unsuitable for ±15 V rail-to-rail use | Select DG419BDJ-E3 when ±15 V signal integrity and guaranteed BBM timing are required |
| ADG1419BRMZ | Lower RDS(on) (1.3 Ω typ), but higher charge injection (12 pC), 36 V supply rating | Better for low-distortion audio routing; less optimal for precision DC-coupled sample-and-hold due to higher leakage | Choose DG419BDJ-E3 for cost-sensitive, high-isolation, low-leakage applications where 15 Ω RDS(on) is acceptable |
Compared with MAX4619ESE+ and ADG1419BRMZ, DG419BDJ-E3 uniquely balances ±15 V rail-to-rail operation, guaranteed break-before-make, and ultra-low leakage (<0.75 nA), making it optimal for military-grade test and measurement where signal fidelity and reliability are non-negotiable.

FAQ
What is the guaranteed break-before-make timing specification for DG419BDJ-E3?
The DG419BDJ-E3 guarantees a minimum break-before-make time delay (tD) of 3 ns over full temperature range, with 16 ns typical at 25 °C. This parameter is measured under RL = 300 Ω and CL = 35 pF conditions with VS1 = VS2 = ±10 V, ensuring no transient shorting between S1 and S2 during switching - a key requirement for DG419BDJ-E3 in safety-critical signal routing applications.
Does DG419BDJ-E3 support single-supply operation?
Yes, DG419BDJ-E3 supports single-supply operation with V+ = 12 V and V− = 0 V, delivering 0 V to 12 V analog signal range and 26 Ω typical RDS(on). The device maintains TTL/CMOS compatibility and retains break-before-make functionality in this configuration, making DG419BDJ-E3 suitable for industrial PLC I/O modules and automotive sensor interfaces where ground-referenced signaling is used.
What is the maximum allowable analog signal voltage beyond the supply rails for DG419BDJ-E3?
DG419BDJ-E3 allows analog signals to exceed V+ or V− by up to ±2 V due to internal clamping diodes, provided forward diode current is limited to the device's maximum current rating (30 mA continuous). This feature protects DG419BDJ-E3 against transient overvoltage events in sensor front-ends, but sustained operation outside the ±15 V specified range may degrade long-term reliability.
How does the VL pin function in DG419BDJ-E3, and can it be tied to V+?
The VL pin supplies independent logic-level power (typically 5 V) to the digital control circuitry, isolating switching noise from the analog section. While VL may be tied to V+ in some configurations, DG419BDJ-E3 datasheet specifies VL = 5 V for guaranteed TTL/CMOS compatibility and optimal timing performance; tying VL to V+ > 5.5 V risks exceeding logic input voltage ratings and invalidates tON/tOFF specifications for DG419BDJ-E3.
Is DG419BDJ-E3 RoHS compliant, and what does the "-E3" suffix indicate?
Yes, DG419BDJ-E3 is RoHS compliant per Directive 2002/95/EC, with lead-free terminations and halogen-free molding compound. The "-E3" suffix explicitly denotes Vishay's industry-standard lead-free, RoHS-compliant packaging - distinct from non-RoHS "DG419BDJ" variants - confirming that DG419BDJ-E3 meets environmental compliance requirements for global electronics manufacturing without derating or special handling.
