Product details
Overview
DG2618DN-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 supply, delivers 4.2 Ω typical on-resistance at 2.7 V, achieves 39 ns turn-on time, and features guaranteed break-before-make switching - enabling high-fidelity audio/video path selection in space-constrained handheld devices.
For engineers reviewing the DG2618DN-T1-E4 datasheet, DG2618DN-T1-E4 pinout, DG2618DN-T1-E4 application, or DG2618DN-T1-E4 equivalent, key selection criteria include its shutdown-enabled control logic (SHDN/EN), charge-pump-assisted low-voltage operation, DFN-10 (3.0 × 3.0 mm) package footprint, and ±150 mA continuous channel current rating.
Technical Context
The DG2618DN-T1-E4 implements a dual SPDT topology with independent COM/NO/NC paths per channel and a dedicated SHDN/EN input that forces both switches into high-impedance off-state when asserted high. Its internal charge pump enables stable RON performance down to 1.5 V supply while maintaining TTL/1.8 V logic compatibility.
Break-before-make timing is guaranteed by design across -40 °C to +85 °C, and latch-up immunity is ensured via epitaxial layer construction. The device supports full analog signal swing from ground to V+, with clamping diodes limiting overvoltage on NC/NO/COM terminals to V+ + 0.3 V.
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 and Li-polymer batteries without level-shifting. |
| On-Resistance (RON) | 4.2 Ω typ. at V+ = 2.7 V, VCOM = 1.5 V - ensures minimal signal attenuation and distortion in audio routing paths. |
| Turn-On Time (tON) | 39 ns max at V+ = 2.7 V - supports fast switching in multi-source video/audio multiplexing applications. |
| Channel Leakage Current | ±10 nA max at V+ = 3.6 V - preserves signal integrity in high-impedance sensor or microphone bias networks. |
| Charge Injection | 7 pC max - minimizes voltage glitch during switching, critical for precision ADC/DAC interface routing. |
| Off-Isolation (OIRR) | -77 dB at 1 MHz - suppresses crosstalk between active and inactive signal paths in shared PCB traces. |

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 supply range (1.08 V to 4.5 V); lower RON (0.7 Ω typ. at 3.3 V); no integrated charge pump. | Requires external 1.8 V or higher supply; better suited for high-speed data lines but lacks 1.5 V native operation. | Select when lowest possible RON and wider voltage margin are prioritized over ultra-low-voltage autonomy. |
| ADG732BRUZ | 32-channel, single-pole single-throw (SPST); no charge pump; 3.5 Ω RON at 3 V; requires external logic for SPDT emulation. | Not pin-compatible; demands additional control logic and PCB area for dual SPDT function replication. | Choose only if system requires >2 channels and can accommodate added complexity for scalability. |
Compared with TMUX1574RTER and ADG732BRUZ, the DG2618DN-T1-E4 uniquely combines native 1.5 V operation, integrated charge pump, guaranteed break-before-make, and true dual SPDT functionality in a 3.0 × 3.0 mm DFN - making it optimal for space- and battery-constrained portable audio/video routing where supply headroom is minimal.

FAQ
What is the minimum operating voltage for DG2618DN-T1-E4?
The DG2618DN-T1-E4 operates down to 1.5 V thanks to its integrated charge pump circuit, which boosts internal gate drive voltage to maintain low on-resistance even at sub-1.8 V supply levels. This capability is confirmed in the Absolute Maximum Ratings and Specifications tables of Vishay document 74411, where RON = 5.3 Ω (max) is specified at V+ = 1.5 V. Below 1.5 V, the DG2618DN-T1-E4 will not function reliably.
Does DG2618DN-T1-E4 support break-before-make switching?
Yes, break-before-make timing is guaranteed by design for the DG2618DN-T1-E4 across its full operating temperature range (-40 °C to +85 °C), as explicitly stated in the product description and verified in the test circuit diagrams (Figure 2). This prevents signal shorting during state transitions, which is critical for audio routing and sensor multiplexing applications where transient shorts could cause audible artifacts or measurement errors.
What is the maximum continuous current rating per channel of DG2618DN-T1-E4?
The DG2618DN-T1-E4 supports ±150 mA continuous current through each NO or NC terminal, as specified in the Absolute Maximum Ratings table (page 2 of document 74411). This rating applies under derated conditions above 70 °C (14.9 mW/°C), and assumes proper PCB thermal management via the exposed DFN-10 thermal pad. Exceeding this current may cause permanent damage or parametric shift.
How does the SHDN/EN pin function on DG2618DN-T1-E4?
The SHDN/EN pin on DG2618DN-T1-E4 is an active-high enable input: when pulled high (≥V+), both switch channels enter high-impedance shutdown mode with RSHDN = 15 Ω (typ.) and leakage <±2 nA. When low (≤0.4 V at V+ = 1.5 V), normal IN1/IN2 control resumes. This behavior is defined in the DG2618 truth table and distinguishes it from DG2616 (no SHDN) and DG2617 (SHDN active-low).
Is DG2618DN-T1-E4 RoHS-compliant and lead-free?
Yes, DG2618DN-T1-E4 is 100 % RoHS-compliant and manufactured with lead (Pb)-free device terminations, as confirmed in the product description on page 1 of Vishay document 74411 and the ordering information table. The DFN-10 package uses matte tin plating over copper, and compliance is verified per EU Directive 2011/65/EU and amendments.
