Product details
Overview
DG2517EDN-T1-GE4 from Vishay Siliconix is a dual SPDT analog switch IC designed for high-bandwidth signal routing in portable and interface applications. It operates from 1.8 V to 5.5 V, delivers 3 Ω on-resistance at 4.2 V, achieves 242 MHz –3 dB bandwidth, and supports +1.6 V logic compatibility - enabling USB/UART and audio/video switching in battery-powered systems.
For engineers reviewing the DG2517EDN-T1-GE4 datasheet, DG2517EDN-T1-GE4 pinout, DG2517EDN-T1-GE4 application, or DG2517EDN-T1-GE4 equivalent, key selection criteria include on-resistance matching (0.2 Ω), off-isolation (–51 dB at 10 MHz), charge injection (2 pC), and DFN-10 package thermal performance (1191 mW power dissipation).
Technical Context
The DG2517EDN-T1-GE4 integrates two independent SPDT switches in a single monolithic CMOS die, each with break-before-make switching action and rail-to-rail analog signal handling (0 V to V+). Its sub-micron process enables low RON flatness (1.1 Ω) and tight channel-to-channel RON match (0.3 Ω max) across temperature and supply voltage.
Control logic accepts 1.6 V–compatible inputs over the full 1.8–5.5 V supply range, with input leakage <1 µA and input capacitance of 4 pF. Dynamic performance includes 12 ns typical turn-on time (V+ = 4.2 V) and 242 MHz small-signal bandwidth into 50 Ω/5 pF load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5.5 V - supports single-supply operation in Li-ion and USB-powered systems without level-shifting. |
| On-Resistance (RON) | 3 Ω at V+ = 4.2 V - minimizes signal attenuation and distortion in audio/video paths. |
| –3 dB Bandwidth | 242 MHz - enables clean switching of USB 1.1 (12 Mbps) and high-speed UART signals. |
| Off-Isolation | –51 dB at 10 MHz - suppresses crosstalk between active and inactive channels in multiplexed interfaces. |
| Charge Injection | 2 pC - reduces glitch-induced DC offset in precision ADC/DAC signal paths. |
| Logic Compatibility | +1.6 V input threshold - ensures reliable control from 1.8 V GPIOs without external translators. |
| RON Matching | 0.3 Ω max - maintains balanced gain and phase in differential or stereo signal routing. |
Pinout & Package
Package: DFN-10 (3 mm × 3 mm, 0.9 mm height), lead (Pb)-free with nickel-palladium-gold terminations (E4 suffix), JEDEC MO-187 compliant, MSL 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | COM1 | Common analog terminal for first SPDT switch - connects to source signal or system node requiring routing. |
| 2 | NC1 | Normally closed terminal for first SPDT - internally connected to COM1 when IN1 = logic low. |
| 3 | V+ | Positive supply rail - powers analog and digital sections; decoupling required within 1 cm. |
| 4 | NC2 | Normally closed terminal for second SPDT - independently controlled by IN2. |
| 5 | COM2 | Common analog terminal for second SPDT - isolated from COM1; supports dual independent signal paths. |
| 6 | IN2 | Digital control input for second switch - active-high; drives internal CMOS transmission gate. |
| 7 | NO2 | Normally open terminal for second SPDT - connects to COM2 only when IN2 = logic high. |
| 8 | GND | Analog/digital ground reference - must be low-impedance and tied to system ground plane. |
| 9 | NO1 | Normally open terminal for first SPDT - provides alternate path for COM1 when IN1 = logic high. |
| 10 | IN1 | Digital control input for first switch - active-high; compatible with 1.6 V logic thresholds. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports full 0 V to V+ swing - preserves dynamic range in audio, video, and sensor interfaces. |
| Break-before-make switching | Prevents momentary shorting between NC and NO paths - avoids signal glitches during state transitions. |
| Low power supply current | 1.0 µA max - enables always-on signal routing in ultra-low-power portable devices. |

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 |
|---|---|---|---|
| MAX4680EUB+T | Higher RON (4.5 Ω), lower bandwidth (150 MHz), MSOP-10 only - no DFN option. | Less suitable for USB 1.1 due to bandwidth limitation; requires larger PCB area. | Choose if MSOP-10 footprint is fixed and 150 MHz bandwidth suffices. |
| ADG732BRUZ | 32-channel, not dual SPDT; 4 Ω RON, 200 MHz bandwidth, TSSOP-38 - significantly larger and more complex. | Over-specified for simple dual-path routing; higher cost and layout overhead. | Choose only if scalable multi-channel expansion is required beyond two SPDTs. |
Compared with MAX4680EUB+T and ADG732BRUZ, the DG2517EDN-T1-GE4 offers optimal balance of bandwidth (242 MHz), low RON (3 Ω), DFN-10 compactness, and 1.6 V logic compatibility - making it the most direct fit for space-constrained, high-speed interface switching where dual independent SPDT functionality is required.

FAQ
What is the maximum analog signal voltage range supported by the DG2517EDN-T1-GE4?
The DG2517EDN-T1-GE4 supports rail-to-rail analog signals from 0 V to V+, where V+ ranges from 1.8 V to 5.5 V. Absolute maximum analog voltage is (V+ + 0.3 V) per pin, clamped by internal diodes. For example, at V+ = 5 V, the safe analog range is 0 V to 5.3 V referenced to GND - ensuring full-swing operation in USB and audio applications without external biasing.
Does the DG2517EDN-T1-GE4 support break-before-make switching, and how is it implemented?
Yes, the DG2517EDN-T1-GE4 implements true break-before-make switching with a guaranteed minimum 1 ns break interval (td). This is achieved via internal timing control that forces both NC and NO paths to disconnect before the new path closes - preventing momentary shorts during logic transitions. The behavior is verified across –40 °C to +85 °C and all supply voltages, making DG2517EDN-T1-GE4 suitable for glitch-sensitive analog routing.
What is the thermal performance of the DG2517EDN-T1-GE4 in its DFN-10 package?
The DG2517EDN-T1-GE4 in DFN-10 has a maximum power dissipation of 1191 mW at +70 °C ambient, derating linearly at 14.9 mW/°C above that. Its thermal resistance θJA is approximately 105 °C/W, enabling operation up to +85 °C ambient with modest PCB copper area (≥1 cm² exposed pad). This makes DG2517EDN-T1-GE4 viable for thermally constrained handheld designs without forced airflow.
Can the DG2517EDN-T1-GE4 be used with 1.8 V microcontroller GPIOs without level shifters?
Yes, the DG2517EDN-T1-GE4 features +1.6 V logic-compatible inputs, meaning it reliably recognizes logic high at ≥1.4 V (typical) and logic low at ≤0.5 V (typical) across the full 1.8–5.5 V supply range. When powered from 1.8 V, its VINH min is 1.4 V - fully compatible with standard 1.8 V CMOS outputs, eliminating need for external level translation circuitry in DG2517EDN-T1-GE4-based designs.
How does the DG2517EDN-T1-GE4 handle ESD and overvoltage on analog pins?
The DG2517EDN-T1-GE4 includes integrated ESD protection diodes on all analog pins (COM, NC, NO), clamping signals to V+ + 0.3 V and GND – 0.3 V. These diodes safely shunt transients up to ±2 kV HBM without latch-up. However, forward diode current must be limited to ±50 mA continuous or ±200 mA pulsed (1 ms, 10% duty cycle) - requiring external series resistors if driving from high-current sources.
