Product details
Overview
DG2515DQ-T1-E3 from Vishay Siliconix is a dual SPDT analog switch IC designed for high-fidelity 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, 235 MHz −3 dB bandwidth, −51 dB off-isolation at 10 MHz, and supports +1.6 V logic compatibility - enabling USB/UART and audio/video switching in space-constrained designs.
For engineers reviewing the DG2515DQ-T1-E3 datasheet, DG2515DQ-T1-E3 pinout, DG2515DQ-T1-E3 application, or DG2515DQ-T1-E3 equivalent, key selection criteria include rail-to-rail analog swing, low charge injection (49 pC at 5 V), tight RON matching (0.3 Ω max), sub-70 ns switching times, and MSOP-10 footprint compatibility with PCB layout constraints for high-density portable systems.
Technical Context
The DG2515DQ-T1-E3 implements a CMOS-based dual SPDT architecture with break-before-make switching action and internal ESD protection. Its sub-micron process enables full rail analog signal handling (0 V to V+) while maintaining low power supply current (≤1 µA) across −40 °C to +85 °C.
Control logic uses single-polarity digital inputs compatible with 1.6 V thresholds at 3 V supply and 2.0 V at 5 V supply. Channel isolation is achieved via optimized gate oxide design, delivering −71 dB off-isolation at 1 MHz and −51 dB at 10 MHz with 17 pF off-capacitance per NC/NO terminal.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPDT analog switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMUX6219RTER | Higher RON (4.5 Ω typ), wider supply (±5 V dual or 12 V single), lower bandwidth (150 MHz), integrated fault protection. | Better suited for industrial sensor multiplexing with overvoltage tolerance; not optimized for USB 2.0 or audio THD. | Select TMUX6219RTER when ±5 V operation or fault protection is required; DG2515DQ-T1-E3 remains preferred for battery-powered USB/audio where low RON and bandwidth are critical. |
| ADG732BRUZ | 32-channel, serial-controlled, higher RON (4.0 Ω), lower bandwidth (100 MHz), SPI interface, larger TSSOP-48 package. | Targets high-channel-count data acquisition, not compact dual-path routing; requires microcontroller coordination. | Choose ADG732BRUZ for scalable multichannel systems needing SPI configuration; DG2515DQ-T1-E3 offers simpler parallel control and smaller footprint for dual-path needs. |
Compared with TMUX6219RTER and ADG732BRUZ, the DG2515DQ-T1-E3 provides superior bandwidth and lower on-resistance in a compact MSOP-10 package - making it optimal for space-constrained, high-speed dual-path applications like USB 2.0 and portable audio, where minimal signal degradation and simple GPIO control are essential.

FAQ
What is the maximum analog signal voltage range supported by the DG2515DQ-T1-E3?
The DG2515DQ-T1-E3 supports a full rail analog signal range from 0 V to V+, where V+ can be set between 1.8 V and 5.5 V. This means that with a 5 V supply, the device passes signals from 0 V to 5 V without clipping or distortion - a key enabler for USB 2.0 differential pair routing and line-level audio applications where headroom preservation is critical. Absolute maximum analog voltage is limited to V+ + 0.3 V per internal clamp diode rating.
Does the DG2515DQ-T1-E3 support break-before-make switching, and why does it matter?
Yes, the DG2515DQ-T1-E3 implements guaranteed break-before-make switching with >1 ns dead time between NC and NO path transitions. This prevents momentary short-circuits during state changes - essential in applications like USB port selection or audio source switching where simultaneous connection of two signal sources could cause latch-up, signal corruption, or damage to downstream receivers. The timing is process-verified and does not require external timing control.
How does the DG2515DQ-T1-E3 achieve 1.6 V logic compatibility across its full 1.8–5.5 V supply range?
The DG2515DQ-T1-E3 uses adaptive input threshold circuitry that scales VINH and VINL relative to V+. At 3 V supply, VINH is guaranteed ≥1.4 V; at 5 V supply, VINH rises to ≥2.0 V - ensuring reliable recognition of 1.6 V–2.0 V logic outputs from modern low-voltage MCUs and PMICs without level shifters. This feature directly enables direct GPIO control from 1.8 V SoCs in battery-powered devices.
What is the significance of the "-E3" suffix in DG2515DQ-T1-E3?
Per Vishay documentation, the "-E3" suffix indicates 100 % matte tin device terminations, confirming RoHS compliance and lead-free construction. This designation reflects Vishay's standardized marking for analog switches built with environmentally compliant finishes, validated for solderability and long-term intermetallic stability under JEDEC J-STD-020 reflow profiles - critical for automotive and medical-grade manufacturing traceability.
Can the DG2515DQ-T1-E3 be used in place of the DG2516DQ-T1-E3, and what is the functional difference?
No - DG2515DQ-T1-E3 and DG2516DQ-T1-E3 have inverted logic polarity: DG2515 connects NC to COM when IN = low (standard SPDT), while DG2516 connects NO to COM when IN = low (inverted SPDT). Pinouts are identical, but truth tables differ. Substituting one for the other without adjusting control logic will reverse switching behavior - potentially causing signal path misrouting or system failure. Always verify logic sense in schematic capture.
