Product details
Overview
DG2617DN-T1-E4 from Vishay Siliconix is a low-voltage dual SPDT analog switch with integrated charge pump, designed for signal routing in portable battery-powered systems. It operates from 1.5 V to 3.6 V, delivers 4.2 Ω typical on-resistance at 2.7 V, achieves 39 ns turn-on time, and supports TTL/1.8 V logic compatibility - enabling high-fidelity audio/video switching in space-constrained handheld devices.
For engineers reviewing the DG2617DN-T1-E4 datasheet, DG2617DN-T1-E4 pinout, DG2617DN-T1-E4 application, or DG2617DN-T1-E4 equivalent, key selection criteria include its shutdown-enabled dual-SPDT configuration, guaranteed break-before-make timing, charge-pump–enabled low-voltage operation down to 1.5 V, and DFN-10 (3.0 × 3.0 mm) package for compact PCB layout.
Technical Context
The DG2617DN-T1-E4 implements a dual single-pole double-throw (SPDT) topology with independent control of two switches via SHDN/EN and IN logic inputs. Its internal charge-pump circuit sustains low RON across the full 1.5–3.6 V supply range without external biasing.
Break-before-make switching is guaranteed per design, preventing momentary shorting between NC and NO paths. The device uses Vishay's low-voltage CMOS process with epitaxial layer latch-up protection and supports ±150 mA continuous current per channel (NO/NC/COM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5 V to 3.6 V - enables direct interface with single-cell Li-ion or Li-poly batteries without level-shifting. |
| On-Resistance (RON) | 4.2 Ω typ. at V+ = 2.7 V, VCOM = 1.5 V - minimizes signal attenuation and distortion in audio path routing. |
| Turn-On Time (tON) | 39 ns max at V+ = 2.7 V - supports high-speed video signal switching up to ~10 MHz bandwidth. |
| Off-Isolation (OIRR) | −77 dB at 1 MHz - ensures >70 dB crosstalk suppression between active and inactive channels. |
| Charge Injection | 7 pC max - limits voltage glitch on sensitive ADC input or audio DAC output nodes. |
| Logic Compatibility | TTL/1.8 V - allows direct connection to baseband processors and application SoCs without external translators. |
| Shutdown Current | 0.1 µA typ. at V+ = 3.6 V - reduces system standby power in always-on mobile peripherals. |

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 |
|---|---|---|---|
| TMUX1574RTER | Higher 5.5 V max supply; no integrated charge pump; 5.2 Ω RON at 3.3 V. | Requires ≥2.5 V supply for low RON; unsuitable for 1.5–1.8 V battery-only operation. | Select when system uses 3.3 V rail and needs higher ESD rating (±4 kV HBM). |

FAQ
What is the minimum operating voltage for the DG2617DN-T1-E4?
The DG2617DN-T1-E4 operates down to 1.5 V thanks to its integrated charge-pump circuit, which maintains low on-resistance without requiring external high-voltage rails. This allows direct use with single-cell lithium batteries at end-of-discharge voltage, unlike standard analog switches that typically require ≥2.5 V. The DG2617DN-T1-E4 datasheet specifies guaranteed performance across the full 1.5 V to 3.6 V range.
Does the DG2617DN-T1-E4 support break-before-make switching?
Yes, break-before-make timing is guaranteed by design in the DG2617DN-T1-E4 - meaning the NC and NO paths are never simultaneously connected during logic transitions. This prevents momentary shorts that could damage downstream components like audio amplifiers or ADC inputs. The specification sheet confirms this behavior is ensured across the full −40 °C to +85 °C operating range without production testing.
How does the charge pump in the DG2617DN-T1-E4 function?
The DG2617DN-T1-E4 integrates an on-chip charge pump that generates an internal boosted voltage to drive the gate of the analog switch transistors, enabling low RON even at 1.5 V supply. When SHDN/EN = LOW, the charge pump is active; when SHDN/EN = HIGH, it disables to reduce quiescent current to 0.1 µA. No external capacitors or control signals are required - the functionality is fully self-contained within the DG2617DN-T1-E4 die.
What is the thermal pad connection requirement for the DG2617DN-T1-E4 DFN-10 package?
The DG2617DN-T1-E4 DFN-10 package includes an exposed thermal pad (pin #3 is GND, but the underside slug is electrically connected to GND). Vishay recommends soldering the pad directly to a PCB thermal plane using a 3×3 array of solder paste dots to ensure mechanical stability and optimal thermal dissipation. Manual iron soldering is not advised due to the leadless construction and risk of insufficient interconnection at the copper lip.
Can the DG2617DN-T1-E4 handle bidirectional analog signals?
Yes, the DG2617DN-T1-E4 supports fully bidirectional analog signal routing - its CMOS switch architecture imposes no polarity restrictions on signals applied to COM, NO, or NC terminals. Signals can swing from GND to V+ (0 V to 3.6 V), and the device maintains symmetrical RON, leakage, and capacitance characteristics regardless of direction. This makes the DG2617DN-T1-E4 suitable for both audio line-level switching and bidirectional I²C bus multiplexing.
