Product details
Overview
DG2517DQ-T1-E3 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, 242 MHz −3 dB bandwidth, −51 dB off-isolation at 10 MHz, and supports +1.6 V logic-compatible control - enabling USB/UART and audio/video switching in battery-powered systems.
For engineers reviewing the DG2517DQ-T1-E3 datasheet, DG2517DQ-T1-E3 pinout, DG2517DQ-T1-E3 application, or DG2517DQ-T1-E3 equivalent, key selection criteria include rail-to-rail analog swing, low charge injection (1–2 pC), tight RON matching (0.2 Ω typ), sub-30 ns switching times, and MSOP-10 lead-free packaging with matte tin terminations.
Technical Context
The DG2517DQ-T1-E3 implements two independent SPDT switches in a single monolithic CMOS process, each with break-before-make timing (≤1 ns) and internal clamping diodes for overvoltage protection. Its sub-micron design enables low power supply current (≤1 µA) and full rail analog signal handling (0 V to V+).
Control logic is compatible with 1.6 V inputs across the full 1.8–5.5 V supply range, and dynamic performance is specified with 300 Ω load and 35 pF capacitance - yielding tON ≤ 25 ns and tOFF ≤ 20 ns at 4.2 V, supporting high-speed digital interface routing without distortion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5.5 V - supports direct interfacing with Li-ion battery rails and 3.3 V/5 V logic domains. |
| On-Resistance (RON) | 3 Ω at V+ = 4.2 V - ensures minimal insertion loss and signal attenuation in audio/video paths. |
| −3 dB Bandwidth | 242 MHz - enables clean switching of USB 1.1 (12 Mbps) and high-definition video baseband signals. |
| Off-Isolation | −51 dB at 10 MHz - suppresses crosstalk between active and inactive channels in multi-source systems. |
| Charge Injection | 1 pC at 3 V, 2 pC at 5 V - minimizes voltage glitches during switching, critical for precision ADC/DAC interfaces. |
| RON Matching | 0.2 Ω typical - maintains channel-to-channel signal integrity in differential or stereo routing applications. |
| Logic Threshold | +1.6 V high-level input - allows direct drive from 1.8 V GPIOs without level-shifting circuitry. |
Pinout & Package
Package: MSOP-10, 3.0 mm × 4.9 mm, 0.5 mm pitch, lead-free matte tin termination (−E3 suffix), JEDEC MO-187 AA/BA compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 10 | COM1 / COM2 | Common analog terminals - bidirectional signal ports connecting to source or load in SPDT configuration. |
| 2, 9 | NC1 / NC2 | Normally closed analog terminals - connected to COM when IN = logic low (0 V). |
| 3, 8 | IN1 / IN2 | Digital control inputs - TTL/CMOS-compatible; active-low logic selects NC path, active-high selects NO path. |
| 4, 7 | NO1 / NO2 | Normally open analog terminals - connected to COM only when IN = logic high (≥1.6 V). |
| 5, 6 | GND / V+ | Ground reference and positive supply - decoupling capacitor required at V+ pin for stable high-frequency operation. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | 0 V to V+ range - preserves full dynamic range of audio, sensor, or data signals without clipping. |
| Break-before-make switching | <1 ns interval - prevents momentary shorting between NC and NO paths, eliminating signal transients. |
| Low off-capacitance | 8 pF per NC/NO terminal - reduces loading on high-impedance sources and preserves bandwidth in RF-adjacent layouts. |
| High linearity (low THD) | Flat RON (1 Ω max variation) - maintains amplitude fidelity across signal swing, essential for audio fidelity. |
| ESD robustness | ±2 kV HBM - protects against handling damage during PCB assembly and system integration. |

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 (190 MHz), same MSOP-10 package. | Less suitable for 242 MHz USB 1.1 routing; acceptable for audio-only paths. | Select if cost sensitivity outweighs bandwidth requirement and existing layout uses MAX4680 footprint. |
| TS5A23157DCUR | Lower supply range (1.65–5.5 V), higher RON (6.5 Ω), smaller DFN-10 package (2.0 × 2.0 mm). | Better for space-constrained designs but sacrifices signal fidelity in high-frequency routing. | Prefer for ultra-portable devices where board area is critical and 242 MHz bandwidth is not required. |
Compared with MAX4680EUB+T and TS5A23157DCUR, the DG2517DQ-T1-E3 provides superior bandwidth and lower on-resistance in a proven MSOP-10 form factor - making it optimal for USB and high-fidelity audio routing where signal integrity is non-negotiable.

FAQ
What is the maximum analog signal voltage range supported by DG2517DQ-T1-E3?
The DG2517DQ-T1-E3 supports analog signals from 0 V to V+, where V+ ranges from 1.8 V to 5.5 V. This rail-to-rail capability ensures full-swing signal integrity without clipping, and internal clamping diodes protect against overvoltage up to V+ + 0.3 V. The DG2517DQ-T1-E3 is rated for continuous analog voltages within this range under all operating conditions.
Does DG2517DQ-T1-E3 require external pull-up or pull-down resistors on its IN pins?
No, DG2517DQ-T1-E3 does not require external biasing on IN1 or IN2 pins. Its digital inputs are CMOS-compatible with guaranteed logic thresholds (VINH ≥ 1.4 V at 3 V supply, ≥ 2.0 V at 5 V), and input leakage remains below 1 µA across temperature. The DG2517DQ-T1-E3 operates reliably with direct connection to microcontroller GPIOs or FPGA outputs.
Can DG2517DQ-T1-E3 be used in bidirectional signal paths such as USB D+/D−?
Yes, DG2517DQ-T1-E3 supports fully bidirectional analog signal routing - both COM and NO/NC terminals handle signals equally in either direction. Its symmetric RON, low capacitance (8 pF off, 35 pF on), and 242 MHz bandwidth make it suitable for USB 1.1 D+/D− switching. The DG2517DQ-T1-E3 maintains impedance continuity and meets rise/fall time requirements for 12 Mbps signaling.
What is the thermal performance of DG2517DQ-T1-E3 in MSOP-10 package?
In the MSOP-10 package, DG2517DQ-T1-E3 has a power dissipation limit of 320 mW at 25 °C, derating linearly by 4.0 mW/°C above 70 °C. Junction-to-ambient thermal resistance (θJA) is approximately 312.5 °C/W. The DG2517DQ-T1-E3 typically dissipates <100 µW in static operation and <1 mW under switching loads, ensuring safe operation without heatsinking in standard PCB layouts.
Is DG2517DQ-T1-E3 RoHS-compliant and halogen-free?
Yes, DG2517DQ-T1-E3 is RoHS-compliant and features 100 % matte tin device terminations per JEDEC standards. It meets MSL Level 1 rating and is halogen-free per IEC 61249-2-21.
