Product details
Overview
DG419BDQ-T1-E3 from Vishay Siliconix is a precision monolithic SPDT CMOS analog switch in MSOP-8 package, designed for break-before-make signal routing in ±15 V dual-supply systems. It delivers 15 Ω on-resistance, 110 ns turn-on time, and <±0.75 nA off-leakage at ±15.5 V, enabling high-fidelity switching in battery-powered instrumentation and military radios.
For engineers reviewing the DG419BDQ-T1-E3 datasheet, DG419BDQ-T1-E3 pinout, DG419BDQ-T1-E3 application, or DG419BDQ-T1-E3 equivalent, this page provides verified electrical specs, validated MSOP-8 terminal mapping, real-world use cases in precision test equipment and guidance systems, and two confirmed alternative parts with documented functional differences.
Technical Context
The DG419BDQ-T1-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.
Each channel supports bidirectional conduction with symmetrical on-resistance (RDS(on) = 15 Ω typ. at ±15 V), 88 dB off-isolation (OIRR), and −88 dB crosstalk (XTALK) at 1 MHz - critical for low-distortion sample-and-hold and multiplexed sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V - supports full-rail switching of bipolar signals without clipping in precision measurement front-ends |
| RDS(on) | 15 Ω typical - minimizes voltage drop and gain error in low-impedance signal paths |
| tON/tOFF | 110 ns / 88 ns - enables fast multiplexing in data acquisition systems up to ~5 MHz effective throughput |
| Off-Leakage (IS(off)) | ±0.75 nA max at ±15.5 V - ensures sub-μV offset drift in high-impedance integrator or amplifier inputs |
| Charge Injection | 38 pC - limits step-induced error in sample-and-hold circuits with ≤10 nF hold capacitors |
| OIRR / XTALK | −82 dB / −88 dB at 1 MHz - suppresses coupling between channels in multi-signal routing applications |
| Supply Voltage Range | V+ = 20 V, V− = −20 V - accommodates overvoltage transients in industrial control I/O modules |
Pinout & Package
Package: MSOP-8 (JEDEC MO-187, variation AA/BA), 3.00 mm × 4.90 mm footprint, 0.65 mm pitch, 1.10 mm max height - optimized for space-constrained portable instrumentation PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Digital control input | Active-high logic: "1" ≥ 2.4 V disables SW1/enables SW2; "0" ≤ 0.8 V enables SW1/disables SW2 |
| 2 (S1) | SPDT source 1 | Common analog input node for first switch path; bidirectional conduction when enabled |
| 3 (D) | SPDT drain (common output) | Shared analog output terminal; connects to S1 or S2 depending on IN logic state |
| 4 (S2) | SPDT source 2 | Second analog input node; isolated from D when SW2 is off (break-before-make enforced) |
| 5 (V−) | Negative supply rail | Bias reference for analog channel operation; must be ≤ −2 V below GND for full ±15 V range |
| 6 (GND) | Digital ground reference | Return path for logic supply (VL) and digital control current; separate from analog ground in mixed-signal layouts |
| 7 (V+) | Positive supply rail | Bias reference for analog channel operation; must be ≥ +2 V above GND for full ±15 V range |
| 8 (VL) | Logic supply voltage | Accepts 5 V TTL/CMOS levels; decoupling required to prevent digital noise coupling into analog paths |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed 16 ns minimum delay between SW1 turn-off and SW2 turn-on prevents momentary shorting in critical signal routing |
| Low on-resistance flatness | ≤2 Ω variation across ±12.5 V analog range - maintains linearity in precision attenuator or gain-switching circuits |
| TTL/CMOS logic compatibility | Direct interface with 5 V microcontrollers and FPGAs without level-shifting, reducing BOM count and layout complexity |
| Epitaxial latchup immunity | Rated for continuous operation in harsh environments (e.g., military radios) without destructive latchup under transient stress |
| RoHS-compliant MSOP-8 | Lead-free terminations meet Directive 2002/95/EC; 0.65 mm pitch enables high-density routing on 4-layer PCBs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4619EUA+ | Higher RDS(on) (35 Ω typ.), wider supply range (±20 V), but no guaranteed break-before-make | Acceptable where timing-critical signal shorting is mitigated by external control sequencing | Select when higher voltage tolerance is prioritized over deterministic switching sequence |
| ADG1419BRMZ | Lower charge injection (12 pC), lower leakage (±0.1 nA), but requires 12 V logic supply for full performance | Better suited for ultra-low-error sample-and-hold; incompatible with 5 V-only control systems | Choose for metrology-grade applications where 5 V logic interface is not required |
Compared with MAX4619EUA+ and ADG1419BRMZ, the DG419BDQ-T1-E3 uniquely guarantees break-before-make timing while maintaining 5 V logic compatibility and 15 Ω on-resistance - making it optimal for cost-sensitive, space-constrained designs requiring deterministic SPDT behavior without external timing control.

FAQ
What is the guaranteed break-before-make time for DG419BDQ-T1-E3?
The DG419BDQ-T1-E3 guarantees a minimum break-before-make time delay (tD) of 16 ns under standard test conditions (RL = 300 Ω, CL = 35 pF, VS1 = VS2 = ±10 V). This parameter is production-tested and ensures no overlap between SW1 turn-off and SW2 turn-on, preventing signal shorting in critical routing paths. The DG419BDQ-T1-E3 datasheet specifies this value at room temperature with ±15 V supplies.
Does DG419BDQ-T1-E3 support unipolar 0 V to 12 V analog signals?
Yes, DG419BDQ-T1-E3 supports unipolar 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 (vs. 15 Ω in ±15 V mode), and tON rises to 100 ns. The DG419BDQ-T1-E3 maintains full functionality including break-before-make timing and TTL/CMOS logic compatibility with VL = 5 V.
What is the maximum allowable logic supply voltage (VL) for DG419BDQ-T1-E3?
The DG419BDQ-T1-E3 specifies VL as (GND − 0.3 V) to (V+) + 0.3 V per Absolute Maximum Ratings. For standard ±15 V operation, VL may range from −0.3 V to +15.3 V. However, functional operation requires VL = 5 V for TTL/CMOS compatibility, and the DG419BDQ-T1-E3 truth table and timing specs are characterized only at VL = 5 V.
Can DG419BDQ-T1-E3 be used with V+ = +15 V and V− = −5 V?
No - DG419BDQ-T1-E3 requires symmetrical dual supplies for guaranteed break-before-make timing and specified RDS(on). The datasheet characterizes performance only at ±15 V, ±13.5 V, and ±12 V. Operation at asymmetric rails (e.g., +15 V/−5 V) falls outside qualified conditions and may degrade tD, increase leakage, or cause undefined switching behavior. The DG419BDQ-T1-E3 is not rated for such configurations.
Is the MSOP-8 package of DG419BDQ-T1-E3 RoHS compliant?
Yes, DG419BDQ-T1-E3 carries the "-E3" suffix indicating lead-free, RoHS-compliant terminations per Directive 2002/95/EC. The MSOP-8 package uses matte tin plating over copper alloy leads, with no exemptions applied. This compliance is verified in Vishay's official documentation (Document Number: 72107, Rev. D) and confirmed on the DG419BDQ-T1-E3 product page at vishay.com.
