Product details
Overview
DG3535DB-T5-E1 from Vishay Siliconix is a low-voltage dual SPDT analog switch in MICRO FOOT 10-bump package, featuring 0.25 Ω on-resistance at 2.7 V, -69 dB off-isolation at 100 kHz, and 1.6 V logic compatibility-designed for audio routing in battery-powered cellular handsets and headset switching.
For engineers reviewing the DG3535DB-T5-E1 datasheet, DG3535DB-T5-E1 pinout, DG3535DB-T5-E1 application, or DG3535DB-T5-E1 equivalent, key selection criteria include guaranteed RON matching (<0.05 Ω), break-before-make timing (1–6 ns), charge injection (21 pC), and ESD robustness (>2 kV HBM).
Technical Context
The DG3535DB-T5-E1 integrates two independent SPDT switches fabricated on high-density low-voltage CMOS with built-in epitaxial latchup protection. Each channel supports bidirectional analog conduction in the ON state and guarantees break-before-make operation to prevent signal shorting during transition.
Its digital control interface accepts 0.5 V/1.4 V logic thresholds across -40 °C to +85 °C, enabling direct interfacing with low-voltage DSPs and microcontrollers. Off-isolation and crosstalk are both -69 dB at 100 kHz, with channel-on capacitance of 406 pF and off-capacitance of 145 pF per NO/NC terminal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 0.25 Ω at 2.7 V - enables <1 mV voltage drop at 100 mA, preserving signal integrity in low-level audio paths |
| RON Matching | ≤0.05 Ω at 2.7 V - ensures matched gain/attenuation between dual channels for stereo or differential signal routing |
| Off-Isolation (OIRR) | -69 dB at 100 kHz - suppresses leakage between inactive paths in multi-source audio/video switching |
| Charge Injection | 21 pC - limits glitch amplitude in precision DC-coupled signal paths when switching |
| Logic Thresholds | VINH = 1.4 V, VINL = 0.5 V - compatible with 1.8 V I/O domains without level-shifting circuitry |
| ESD Protection | >2000 V HBM - withstands handling and board-level electrostatic events in portable device assembly |
| Supply Range | 1.8 V to 6 V - supports single-supply operation from Li-ion battery (3.0–4.2 V) or regulated 3.3 V rails |
Pinout & Package
MICRO FOOT 10-bump (4 × 3 mm, 0.5 mm pitch, 238 µm bump height) package with Pb-free SnAgCu terminations. Land pattern requires non-solder-mask-defined copper pads and 0.1 mm solder mask expansion beyond pad diameter.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1, IN2 | Digital control inputs | Active-high logic inputs controlling respective SPDT switch states; TTL/CMOS compatible |
| COM1, COM2 | Analog common terminals | Bidirectional current paths connecting to either NO or NC based on IN state |
| NO1, NO2 | Normally-open analog outputs | Connected to COMx only when corresponding INx = 1; 406 pF on-capacitance affects high-frequency bandwidth |
| NC1, NC2 | Normally-closed analog outputs | Connected to COMx only when corresponding INx = 0; same RON and capacitance as NO pins |
| V+ | Positive supply rail | Accepts 1.8–6 V; powers internal switch matrix and level translators; decoupling required near pin |
| GND | Ground reference | Return path for analog signals and digital logic; must be low-impedance for noise-sensitive audio routing |
Key Features
| Feature | Design Value |
|---|---|
| Sub-ohm RON with flatness | 0.25 Ω typical at 2.7 V, ≤0.2 Ω variation over full analog range - minimizes insertion loss in headphone and mic paths |
| Guaranteed break-before-make | 1–6 ns minimum dead time - prevents momentary shorting between NO and NC during switching transitions |
| Low-voltage logic interface | 1.6 V compatible input thresholds - eliminates need for external level shifters when driving from 1.8 V processors |
| High off-isolation & crosstalk rejection | -69 dB at 100 kHz - isolates active audio channels from idle sources, reducing audible crosstalk in multi-input systems |
| Integrated ESD protection | >2000 V HBM on all analog and digital pins - meets IEC 61000-4-2 Level 2 for handheld device front-end robustness |

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 |
|---|---|---|---|
| MAX4685EUB+ | Higher RON (0.5 Ω typ at 3 V), larger 10-pin µMAX package (3 × 3 mm), no guaranteed break-before-make | Lower isolation (-55 dB), higher supply current (10 µA), less suitable for ultra-low-noise audio | Preferred where cost sensitivity outweighs audio performance; requires PCB layout change |
| ADG736BRMZ-REEL | 0.4 Ω RON at 3 V, MSOP-10 package, -65 dB OIRR, 12 pC charge injection | Wider supply range (1.8–5.5 V), lower leakage (±10 pA), but no ESD rating published | Selected when lower charge injection is critical and external ESD protection is implemented |
Compared with DG3535DB-T5-E1, MAX4685EUB+ trades audio fidelity for broader availability and ADG736BRMZ-REEL prioritizes charge injection reduction over integrated ESD robustness-neither offers identical RON flatness or guaranteed break-before-make timing.

FAQ
What is the maximum analog signal voltage range supported by the DG3535DB-T5-E1?
The DG3535DB-T5-E1 supports analog signals from 0 V to V+, where V+ ranges from 1.8 V to 6 V. Signals exceeding V+ on NO, NC, or COM pins are clamped by internal diodes; forward diode current must be limited to rated maximums. This allows safe operation with audio signals up to 3.3 V peak-to-peak when powered from a 3.3 V rail, as confirmed in the Absolute Maximum Ratings table.
Does the DG3535DB-T5-E1 require external pull-up or pull-down resistors on its IN1 and IN2 control pins?
No, the DG3535DB-T5-E1 does not require external biasing on IN1 or IN2. Its input structure draws ≤1 µA at VIN = 0 V or V+, and logic thresholds (VINH = 1.4 V, VINL = 0.5 V) are internally defined. Direct connection to 1.8 V or 3.3 V GPIOs is supported without pull resistors, as verified in the Digital Control section of the datasheet.
How is the "-E1" suffix in DG3535DB-T5-E1 defined per Vishay documentation?
The "-E1" suffix in DG3535DB-T5-E1 denotes lead (Pb)-free terminations using tin/silver/copper (SnAgCu) alloy, per RoHS Directive 2002/95/EC compliance. It specifically identifies MICRO FOOT packages with this termination finish, as stated in the Ordering Information and Package sections of Document Number 72961.
Can the DG3535DB-T5-E1 be used in bidirectional analog signal paths?
Yes, the DG3535DB-T5-E1 supports fully bidirectional analog conduction in the ON state: current flows equally from COM to NO/NC or vice versa. This is explicitly stated in the DESCRIPTION section ("all switching elements conduct equally in both directions") and validated by symmetric RON, CON, and leakage specifications for NO and NC terminals.
What thermal derating applies to the DG3535DB-T5-E1 above 70 °C?
The DG3535DB-T5-E1 requires thermal derating above 70 °C: power dissipation must be reduced by 5.7 mW/°C. Its maximum rated power dissipation is 457 mW at ≤70 °C in the MICRO FOOT 10-bump package. This linear derating ensures junction temperature remains within safe limits under sustained load, as specified in Note d of the Absolute Maximum Ratings table.
