Product details
Overview
DG2519EDQ-T1-GE3 from Vishay Siliconix is a monolithic CMOS dual single-pole double-throw (SPDT) analog switch optimized for low-voltage, high-bandwidth signal routing. It delivers 2.5 Ω on-resistance at 5 V, -63 dB off-isolation and crosstalk at 1 MHz, and 217 MHz -3 dB bandwidth, enabling high-fidelity audio/video switching in portable electronics.
For engineers reviewing the DG2519EDQ-T1-GE3 datasheet, DG2519EDQ-T1-GE3 pinout, DG2519EDQ-T1-GE3 application, or DG2519EDQ-T1-GE3 equivalent, key selection criteria include guaranteed break-before-make timing, low charge injection (-14 pC), on-resistance matching (≤0.5 Ω), and MSOP-10 package compatibility with space-constrained PCB layouts.
Technical Context
The DG2519EDQ-T1-GE3 integrates two independent SPDT switches with separate digital control inputs (IN1/IN2 and EN), each supporting bidirectional analog conduction and rail-to-rail signal blocking. Its epitaxial CMOS process prevents latch-up and ensures stable RON flatness (≤1.5 Ω) across the full analog voltage range (0 to V+).
Dynamic performance is defined by fast switching (tON = 14 ns max at 5 V), precise break-before-make timing (2–13 ns), and minimal charge injection (-14 pC), making it suitable for precision sampling and low-distortion signal path management in mixed-signal systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5.5 V single supply - supports direct interface with 1.8 V, 2.7 V, 3.3 V, and 5 V logic and analog rails |
| On-Resistance (RON) | 2.5 Ω typical at V+ = 5 V - enables low insertion loss and minimal signal attenuation in audio/video paths |
| Off-Isolation / Crosstalk | -63 dB at 1 MHz - suppresses inter-channel interference in multi-source routing applications |
| Bandwidth (-3 dB) | 217 MHz - preserves signal integrity for HD video and high-speed data acquisition |
| Charge Injection | -14 pC - reduces glitch-induced error in sample-and-hold and ADC front-end circuits |
| Break-Before-Make Time | 2 ns minimum - prevents momentary shorting between NC and NO paths during state transitions |
| Leakage Current (max) | 2 nA at V+ = 5.5 V - maintains signal fidelity in high-impedance sensor and medical monitoring interfaces |
Pinout & Package
Package: MSOP-10 (3.0 mm × 4.9 mm, 0.5 mm pitch), thermally enhanced with exposed pad per JEDEC MO-187 AA/BA.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 10 | COM1 / COM2 | Common analog terminals - bidirectional signal ports for each SPDT switch |
| 2, 4 | NC1 / NC2 | Normally closed analog terminals - conduct to COM when respective IN = 0 and EN = 1 |
| 3, 7 | NO1 / NO2 | Normally open analog terminals - conduct to COM when respective IN = 1 and EN = 1 |
| 5, 8 | GND / V+ | Ground reference and positive supply - decoupling required at V+ pin for dynamic performance |
| 6 | EN | Global enable input - disables both SPDTs when low, overriding individual IN states |
| 9 | IN | Shared logic input - controls switching state of both SPDTs simultaneously (per truth table) |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog operation | Supports 0 V to V+ signal swing without clipping - essential for unipolar sensor and audio signals |
| Guaranteed break-before-make | Prevents signal shorting during transition - critical for protecting downstream amplifiers and ADCs |
| Low on-resistance matching | ΔRON ≤ 0.5 Ω - ensures channel-to-channel gain consistency in stereo or differential routing |
| ESD robustness | 7.5 kV HBM - withstands handling and board-level ESD events without functional degradation |
| Latch-up immunity | JESD78-compliant 300 mA - eliminates risk of destructive latch-up under overvoltage transients |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMUX6219RSVR | Higher RON (4.2 Ω @ 5 V), lower bandwidth (150 MHz), no guaranteed break-before-make | Less suitable for high-fidelity audio; acceptable for general-purpose multiplexing where timing overlap is tolerable | Select DG2519EDQ-T1-GE3 when break-before-make timing, sub-3 Ω RON, or >200 MHz bandwidth is required |
| ADG726BRUZ | Wider supply range (1.8–5.5 V), but higher charge injection (-25 pC) and no MSOP-10 package option | Acceptable for DC-coupled industrial I/O, but not optimal for precision sampling or portable audio | Choose DG2519EDQ-T1-GE3 for portable designs needing MSOP-10 footprint and <15 pC charge injection |
Compared with TMUX6219RSVR and ADG726BRUZ, the DG2519EDQ-T1-GE3 provides superior timing control (guaranteed BBM), lower on-resistance, and higher bandwidth-making it the preferred choice for high-fidelity portable signal routing where channel integrity and transient suppression are critical.

FAQ
What is the maximum supply voltage rating for DG2519EDQ-T1-GE3?
The DG2519EDQ-T1-GE3 has an absolute maximum supply voltage (V+) of +6 V, with recommended operating range from 1.8 V to 5.5 V. Operation above 5.5 V risks permanent damage, and the device is fully characterized and guaranteed only within the 1.8–5.5 V range per its datasheet specifications. The DG2519EDQ-T1-GE3 must be used with appropriate decoupling and voltage regulation to remain within this window.
Does DG2519EDQ-T1-GE3 support bidirectional analog signal flow?
Yes, the DG2519EDQ-T1-GE3 supports fully bidirectional analog conduction on all COM/NC/NO paths - meaning signals pass with equal performance regardless of direction. This is inherent to its CMOS transmission-gate architecture and confirmed by symmetric RON, leakage, and capacitance specs for both forward and reverse configurations. The DG2519EDQ-T1-GE3 requires no polarity-aware layout or external biasing.
Is DG2519EDQ-T1-GE3 pin-compatible with DG2519EDN-T1-GE4?
No, DG2519EDQ-T1-GE3 (MSOP-10) and DG2519EDN-T1-GE4 (DFN-10) share identical electrical functionality and pin functions but differ in physical package, land pattern, thermal pad configuration, and mechanical dimensions. They are not mechanically interchangeable - PCB redesign is required to substitute one for the other. The DG2519EDQ-T1-GE3 uses a gull-wing leaded MSOP package, while DG2519EDN-T1-GE4 uses a leadless DFN with bottom thermal pad.
What is the guaranteed break-before-make time for DG2519EDQ-T1-GE3?
The DG2519EDQ-T1-GE3 guarantees a minimum break-before-make (BBM) time of 2 ns over the full -40 °C to +85 °C temperature range and 1.8–5.5 V supply range. This is verified per the truth table and dynamic test conditions in the official Vishay datasheet (Document #78595). The DG2519EDQ-T1-GE3 ensures no overlap between NC and NO conduction paths, preventing signal shorting during switching transitions.
Can DG2519EDQ-T1-GE3 operate from a 1.8 V supply with full performance?
Yes, the DG2519EDQ-T1-GE3 is fully specified and guaranteed down to 1.8 V supply, including RON (≤13 Ω), leakage (<5 nA), and switching speed (tON ≤ 50 ns). However, bandwidth drops to ~100 MHz and isolation degrades slightly versus 5 V operation. All logic thresholds scale with V+, so 1.8 V supplies require compatible 0.4 V / 1.5 V input levels. The DG2519EDQ-T1-GE3 maintains functional integrity and specification compliance across its entire 1.8–5.5 V range.
