Product details
Overview
DG2519EDN-T1-GE4 from Vishay Siliconix is a monolithic CMOS dual SPDT analog switch optimized for low-voltage, high-bandwidth signal routing. It operates from 1.8 V to 5.5 V, delivers 2.5 Ω typical on-resistance at 5 V, -63 dB off-isolation at 1 MHz, and 217 MHz -3 dB bandwidth-enabling high-fidelity audio/video switching in portable electronics.
For engineers reviewing the DG2519EDN-T1-GE4 datasheet, DG2519EDN-T1-GE4 pinout, DG2519EDN-T1-GE4 application, or DG2519EDN-T1-GE4 equivalent, key selection criteria include guaranteed break-before-make timing (min 2 ns), low charge injection (-14 pC), matched on-resistance (≤0.5 Ω max ΔRDS(on)), and DFN-10 package compatibility with space-constrained PCB layouts.
Technical Context
The DG2519EDN-T1-GE4 integrates two independent SPDT switches with CMOS control logic, each supporting bidirectional analog signal conduction up to the supply rail. Its epitaxial layer prevents latch-up, and internal clamping diodes protect terminals against overvoltage transients beyond V+.
Break-before-make operation is guaranteed across temperature (-40 °C to +85 °C) and supply voltage (1.8–5.5 V). Dynamic performance includes 14 ns max turn-on time, 35 ns max turn-off time, and <15 ps propagation delay-critical for low-jitter signal path integrity in multi-channel audio routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | 1.8 V to 5.5 V single supply - enables direct interface with 1.8 V, 3.3 V, and 5 V logic and analog systems without level shifting. |
| On-Resistance (RDS(on)) | 2.5 Ω typical at V+ = 5 V - minimizes signal attenuation and distortion in audio line-level and video baseband paths. |
| Off-Isolation / Crosstalk | -63 dB at 1 MHz - suppresses channel-to-channel interference in multi-source audio/video multiplexing. |
| Bandwidth (-3 dB) | 217 MHz - supports composite video (NTSC/PAL), USB 2.0 data lines, and wideband instrumentation signals. |
| Charge Injection | -14 pC - reduces glitch-induced DC offset in precision ADC front-ends and sample-and-hold circuits. |
| Switching Speed | tON ≤ 43 ns, tOFF ≤ 35 ns - ensures fast channel selection in real-time audio mixing and ATE test sequencing. |
| Leakage Current | ≤ 2 nA max off-state leakage - preserves signal integrity in high-impedance sensor interfaces and battery-powered standby modes. |
Pinout & Package
DFN-10 (3 mm × 3 mm, 0.5 mm pitch) with exposed thermal pad. Compact footprint supports high-density portable PCBs while enabling efficient heat dissipation during sustained switching.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 10 | V+ | Positive supply rail - must be decoupled locally; powers analog core and digital control logic. |
| 2, 9 | COM1 / COM2 | Common analog terminals - bidirectional signal ports connecting to source or load in each SPDT path. |
| 3, 8 | NC1 / NC2 | Normally closed switch terminals - conduct to COM when EN = 0; isolated when EN = 1. |
| 4, 7 | NO1 / NO2 | Normally open switch terminals - conduct to COM when EN = 1; isolated when EN = 0. |
| 5 | GND | Analog/digital ground reference - shared return for supply and signal paths; requires low-impedance connection. |
| 6 | EN | Global enable input - active-high TTL/CMOS-compatible control for simultaneous dual-switch operation. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed break-before-make | Ensures no momentary short between NC and NO paths during switching - eliminates signal glitches in audio crosspoints. |
| Low on-resistance flatness | ≤1.5 Ω variation across full analog voltage range - maintains consistent gain and THD in variable-amplitude signals. |
| High off-isolation at 10 MHz | -22 dB - mitigates RF coupling in mixed-signal handheld devices with cellular/Wi-Fi coexistence. |
| ESD robustness | 7.5 kV HBM - withstands handling and system-level ESD events without latch-up or parameter shift. |
| Low power supply current | ≤1 μA max - extends battery life in always-on headset detection and audio jack insertion sensing circuits. |

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 |
|---|---|---|---|
| TMUX6219RTER | Higher RON (4.5 Ω typ), wider supply (±5 V dual / 10 V single), no break-before-make guarantee | Better suited for bipolar signal conditioning; less suitable for low-voltage portable audio due to higher RON and larger package | Select TMUX6219RTER only if dual-supply operation or higher voltage tolerance (>5.5 V) is required. |
| ADG732BRUZ | 32-channel, not dual SPDT; 4 Ω RON; SPI interface instead of parallel EN control | Designed for high-channel-count ATE and automated test systems-not drop-in replacement for discrete dual-path routing | Choose ADG732BRUZ only when scalable channel count and serial configuration outweigh compact dual-SPDT simplicity. |
Compared with TMUX6219RTER and ADG732BRUZ, the DG2519EDN-T1-GE4 uniquely balances ultra-low on-resistance, guaranteed break-before-make timing, and DFN-10 footprint-making it optimal for space-constrained, battery-sensitive dual-path audio/video routing where deterministic switching behavior is mandatory.

FAQ
What is the maximum analog signal voltage range supported by the DG2519EDN-T1-GE4?
The DG2519EDN-T1-GE4 supports analog signals from 0 V to V+, where V+ ranges from 1.8 V to 5.5 V. This rail-to-rail capability allows full-swing signal handling without clipping-critical for audio line-level signals and video baseband routing. Absolute maximum analog voltage is limited to (V+ + 0.3 V) due to internal clamping diodes, as specified in the absolute maximum ratings table.
Does the DG2519EDN-T1-GE4 require external pull-up or pull-down resistors on its EN pin?
No, the DG2519EDN-T1-GE4 does not require external pull-up or pull-down resistors on the EN pin. Its digital inputs exhibit ≤1 μA leakage across -40 °C to +85 °C, and the input thresholds (VINH ≥ 2 V, VINL ≤ 0.5 V at V+ = 5 V) are compatible with standard CMOS logic families. Internal design ensures stable logic states without external biasing under normal operating conditions.
Can the DG2519EDN-T1-GE4 be used in bidirectional USB 2.0 data switching applications?
The DG2519EDN-T1-GE4 supports bidirectional signal routing with 217 MHz bandwidth and low capacitance (24 pF on, 7 pF off), making it technically viable for USB 2.0 data lines (480 Mbps, ~240 MHz fundamental). However, it is not USB-certified, lacks differential pair matching, and has no integrated ESD protection beyond 7.5 kV HBM-so it should only be used in non-compliant, internally routed signal paths where full USB 2.0 electrical compliance is not required.
What thermal considerations apply to the DG2519EDN-T1-GE4 in continuous operation?
The DG2519EDN-T1-GE4 in DFN-10 package has a thermal resistance θJA of 14.9 mW/°C above 70 °C ambient, with maximum power dissipation rated at 1191 mW. For continuous operation, maintain junction temperature below 150 °C by ensuring adequate PCB copper area under the exposed pad and limiting total channel current to ≤50 mA per terminal. Derating begins at 70 °C ambient per datasheet note 4d.
How does the DG2519EDN-T1-GE4 ensure signal integrity during fast switching transitions?
The DG2519EDN-T1-GE4 ensures signal integrity via guaranteed break-before-make timing (min 2 ns), low charge injection (-14 pC), and matched on-resistance (≤0.5 Ω ΔRDS(on)). These features minimize transient glitches, DC offset steps, and gain mismatch-preserving waveform fidelity in audio crosspoints and precision data acquisition. The 217 MHz bandwidth further ensures minimal phase distortion up to video frequencies.
