Product details
Overview
DG2517DN-T1-E4 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 space-constrained DFN-10 layouts.
For engineers reviewing the DG2517DN-T1-E4 datasheet, DG2517DN-T1-E4 pinout, DG2517DN-T1-E4 application, or DG2517DN-T1-E4 equivalent, key selection criteria include its rail-to-rail analog signal swing, low 1 Ω RON flatness, −51 dB off-isolation at 10 MHz, and Pb-free nickel-palladium-gold termination qualified per JEDEC reflow standards.
Technical Context
The DG2517DN-T1-E4 integrates two independent SPDT switches in a single monolithic CMOS die, each with break-before-make timing (≤1 ns) and matched on-resistance (ΔRON ≤ 0.4 Ω). Its sub-micron process enables full rail signal handling (0 V to V+) while maintaining low charge injection (2 pC) and low input capacitance (4 pF).
Control logic accepts 1.6 V–compatible inputs across the full 1.8–5.5 V supply range, eliminating level-shifting in mixed-voltage systems. Dynamic performance is characterized with 300 Ω load and 35 pF capacitance, yielding typical tON/tOFF of 12/8 ns at 4.2 V - optimized for high-speed digital interface and audio path switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | 1.8 V to 5.5 V - supports direct interfacing with Li-ion battery rails and 3.3 V/5 V logic without regulators |
| RON (max) | 4.3 Ω at 5 V - ensures minimal voltage drop and signal attenuation in 50 Ω–300 Ω impedance paths |
| −3 dB Bandwidth | 242 MHz - preserves integrity of USB 1.1 (12 Mbps), UART up to 10 Mbps, and composite video signals |
| Off-Isolation | −51 dB at 10 MHz - suppresses crosstalk between active and inactive channels in multi-signal routing |
| Logic Threshold | VINH = 2.0 V, VINL = 0.8 V at 5 V - guarantees reliable switching with 1.8 V–3.3 V microcontroller GPIOs |
| Charge Injection | 2 pC - limits glitch-induced DC offset in precision ADC/DAC signal paths and audio line drivers |
| Package | DFN-10 (3 mm × 3 mm, 0.9 mm height) - enables compact PCB layout with exposed thermal pad for power dissipation up to 1191 mW |
Pinout & Package
DFN-10 package with exposed thermal pad (pin 10), 0.5 mm pitch, JEDEC MO-187-compliant footprint. Pin 1 marked by index area; no internal die paddle connection required for electrical operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (COM1) | Analog common terminal, Switch 1 | Primary signal path junction - connects to source in SPDT configuration; must be routed with controlled impedance |
| 2 (NC1) | Normally closed terminal, Switch 1 | Connected to COM1 when IN1 = 0; used for default-path routing or fail-safe signal continuity |
| 3 (V+) | Positive supply | Single power rail for analog and digital sections; bypassing with 100 nF ceramic capacitor near pin is mandatory |
| 4 (NC2) | Normally closed terminal, Switch 2 | Independent of Switch 1; enables dual-channel isolation without shared control logic |
| 5 (COM2) | Analog common terminal, Switch 2 | Second independent signal path; supports differential or separate signal routing (e.g., stereo audio L/R) |
| 6 (IN2) | Digital control input, Switch 2 | Inverted logic: low = NC2 connected, high = NO2 connected; compatible with 1.6 V–5.5 V logic families |
| 7 (NO2) | Normally open terminal, Switch 2 | Activated when IN2 = high; provides alternate path for dynamic signal reconfiguration |
| 8 (GND) | Analog/digital ground | Common reference for all analog signals and logic inputs; must connect directly to PCB ground plane |
| 9 (NO1) | Normally open terminal, Switch 1 | Activated when IN1 = high; pairs with COM1/NC1 to form first SPDT switch |
| 10 (IN1) | Digital control input, Switch 1 | Independent TTL/CMOS-compatible control; allows asynchronous switching of two signal paths |
Key Features
| Feature | Design Value |
|---|---|

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 (12 Ω), lower bandwidth (100 MHz), MSOP-10 only | Less suitable for USB 1.1 or >5 MHz video; better for general-purpose low-speed muxing | Choose when board space allows larger MSOP and bandwidth requirements are relaxed |
| ADG732BRUZ | 32-channel, serial-controlled, 4 Ω RON, 200 MHz bandwidth, TSSOP-38 | Requires SPI interface and firmware overhead; not pin-compatible for simple GPIO control | Prefer when system already uses SPI peripherals and needs scalable channel count |
Compared with MAX4680EUB+T and ADG732BRUZ, the DG2517DN-T1-E4 offers superior bandwidth and lower on-resistance in a compact DFN-10 package, making it optimal for space-constrained, high-speed interface routing where parallel GPIO control is available.

FAQ
What is the maximum analog signal voltage range supported by the DG2517DN-T1-E4?
The DG2517DN-T1-E4 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 utilization of the supply voltage range without clamping or external biasing - critical for preserving dynamic range in audio and video applications. Absolute maximum analog voltage is V+ + 0.3 V, but operation beyond V+ risks diode conduction and signal distortion. The DG2517DN-T1-E4 maintains specified RON flatness and bandwidth across this entire range.
Does the DG2517DN-T1-E4 require external pull-up or pull-down resistors on its digital control inputs?
No, the DG2517DN-T1-E4 does not require external pull-up or pull-down resistors on IN1 or IN2. Its digital inputs are CMOS-compatible with guaranteed VINH = 2.0 V and VINL = 0.8 V at V+ = 5 V, and operate reliably down to 1.6 V logic thresholds across the full 1.8–5.5 V supply range. Input leakage is ≤1 µA, so microcontroller GPIOs can drive the pins directly. External resistors are unnecessary unless system-level noise immunity or default-state assurance is required beyond the IC's native specifications.
How does the DG2517DN-T1-E4 handle power supply sequencing when V+ ramps up?
The DG2517DN-T1-E4 features robust power supply sequencing tolerance: digital inputs remain inactive (high-impedance) until V+ reaches ~1.2 V, and analog switching functionality stabilizes once V+ exceeds 1.8 V. During ramp-up, all switches default to the NC (normally closed) state per truth table behavior, preventing undefined signal paths. No special power sequencing is required - V+ may ramp before or after control signals. The DG2517DN-T1-E4 draws <1 µA quiescent current during ramp-up, minimizing inrush impact.
Can the DG2517DN-T1-E4 be used to switch differential USB 2.0 signals?
No, the DG2517DN-T1-E4 is not suitable for USB 2.0 (480 Mbps) differential signaling. Its 242 MHz −3 dB bandwidth and 35 pF channel-on capacitance limit usable data rates to USB 1.1 (12 Mbps) and lower-frequency interfaces. USB 2.0 requires >500 MHz bandwidth, <1 pF capacitance mismatch, and strict differential impedance control - capabilities beyond the DG2517DN-T1-E4's design. For USB 2.0, dedicated high-speed analog switches like the TS3USB221A are recommended. The DG2517DN-T1-E4 remains appropriate for USB 1.1, UART, and audio.
What thermal considerations apply to the DG2517DN-T1-E4 in continuous operation?
The DG2517DN-T1-E4 has a maximum power dissipation of 1191 mW in DFN-10 package, with thermal derating of 14.9 mW/°C above 70 °C ambient. In continuous operation at 5 V with 10 mA per channel, power dissipation is ~0.5 mW - well within safe limits. However, PCB layout must include the exposed thermal pad (pin 10) soldered to a minimum 100 mm² copper pour for effective heat transfer. Junction-to-ambient thermal resistance (θJA) is 105 °C/W with proper layout; without thermal pad connection, θJA rises significantly, risking thermal shutdown at elevated ambient temperatures.
