Product details
Overview
DG3537DB-T5-E1 from Vishay Siliconix is a dual SPST analog switch designed for high-fidelity audio, video, and USB signal routing in portable electronics. It operates from 1.8 V to 5.5 V, delivers 3 Ω on-resistance at 2.7 V, supports 360 MHz −3 dB bandwidth, features 0.2 Ω channel-to-channel RON matching, and uses a lead-free MICRO FOOT® 8-bump (3 × 3 mm) package.
For engineers reviewing the DG3537DB-T5-E1 datasheet, DG3537DB-T5-E1 pinout, DG3537DB-T5-E1 application, or DG3537DB-T5-E1 equivalent, this page provides verified electrical parameters, functional pin mapping, real-world use cases in media devices, and validated alternative parts for design flexibility and supply continuity.
Technical Context
The DG3537DB-T5-E1 implements two independent single-pole single-throw (SPST) switches with complementary logic control: IN1/IN2 drive NO1/NO2 to ON when low, and NC1/NC2 remain OFF; logic high reverses states. Its sub-micron process enables rail-to-rail analog signal swing (0 V to V+), low charge injection (1 pC), and full 1.6 V logic compatibility across the entire 1.8–5.5 V supply range.
Dynamic performance includes 11–46 ns turn-on time (V+ = 4.2 V), −78.5 dB off-isolation at 1 MHz, and −113 dB crosstalk - optimized for low-distortion switching in high-speed data and audio paths where signal integrity and minimal timing skew between channels are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5.5 V single rail - enables direct interface with Li-ion battery systems and low-voltage logic without level shifters |
| On-Resistance (RON) | 3 Ω typ. at 2.7 V - ensures minimal insertion loss and voltage drop in audio and USB 2.0 signal paths |
| −3 dB Bandwidth | 360 MHz - supports full-speed USB 2.0 (480 Mbps) and composite video switching without attenuation |
| RON Matching | 0.2 Ω max. between channels - preserves amplitude balance in stereo audio or differential signaling applications |
| Charge Injection | 1 pC - reduces glitch-induced DC offset in precision ADC/DAC multiplexing and sample-hold circuits |
| Off-Isolation @ 1 MHz | −78.5 dB - prevents signal bleed-through between active and inactive channels in multi-source routing |
| Logic Compatibility | 1.6 V input threshold - guarantees reliable switching with 1.8 V CMOS outputs without external pull-ups |
Pinout & Package
MICRO FOOT® 8-bump chip-scale package (3 mm × 3 mm, 0.5 mm pitch, 238 µm bump height); Pb-free Sn/Ag/Cu terminations; bottom-side die attach with laser-marked top-side identification ('3537' + traceability code).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1 | Digital control input for Channel 1 | Active-low logic: drives NO1 ON / NC1 OFF when low; complements IN2 for dual independent switching |
| IN2 | Digital control input for Channel 2 | Active-low logic: drives NO2 ON / NC2 OFF when low; isolated from IN1 for asynchronous operation |
| COM1 | Analog common terminal, Channel 1 | Primary signal path node - connects to source in SPST configuration; supports full rail swing (0 V to V+) |
| COM2 | Analog common terminal, Channel 2 | Independent analog path - electrically isolated from COM1; enables true dual-channel signal routing |
| NO1 | Normally-open terminal, Channel 1 | Closes to COM1 when IN1 = low; open-circuit leakage < ±20 nA ensures signal integrity during OFF state |
| NO2 | Normally-open terminal, Channel 2 | Closes to COM2 when IN2 = low; matched RON and capacitance to NO1 for balanced channel performance |
| GND | Ground reference | Common return for digital logic and analog substrate; must be low-impedance to minimize noise coupling |
| V+ | Positive supply rail | Single power input for analog and digital sections; decoupling capacitor required within 1 cm of V+/GND pins |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports 0 V to V+ input/output swing - eliminates clipping in audio codecs and video DAC outputs |
| Low 1 pC charge injection | Minimizes transient glitches in precision sampling circuits - critical for 16-bit+ ADC front-end multiplexing |
| 0.2 Ω RON matching | Ensures amplitude consistency between left/right audio channels or differential data pairs |
| 360 MHz −3 dB bandwidth | Preserves edge integrity for USB 2.0 data packets and NTSC/PAL video signals without filtering |
| 1.6 V logic-compatible inputs | Directly interfaces with 1.8 V I/O domains - removes need for external level translators in modern SoC designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4680EUB+ | Higher RON (4.5 Ω typ. at 3 V), lower bandwidth (200 MHz), same MICRO FOOT 8-bump footprint | Less suitable for USB 2.0; acceptable for audio-only routing where bandwidth margin is relaxed | Select MAX4680EUB+ only if supply voltage is fixed at 3.3 V and bandwidth demand ≤ 200 MHz |
| ADG721BRMZ-REEL7 | Lower RON (2.5 Ω typ. at 3 V), higher bandwidth (375 MHz), MSOP-8 package (3 × 3 mm body, but leads require PCB rework) | Requires layout change due to gull-wing leads; better for high-precision audio where RON flatness < 0.5 Ω is mandatory | Choose ADG721BRMZ-REEL7 only when upgrading from DG3537DB-T5-E1 and board space allows MSOP-8 rework |
Compared with MAX4680EUB+ and ADG721BRMZ-REEL7, the DG3537DB-T5-E1 uniquely balances 3 Ω RON, 360 MHz bandwidth, and MICRO FOOT chip-scale packaging - making it optimal for space-constrained, multi-standard portable devices where both USB 2.0 and wideband audio coexist on one PCB.

FAQ
What is the maximum supply voltage rating for DG3537DB-T5-E1?
The absolute maximum supply voltage (V+ to GND) for DG3537DB-T5-E1 is +6.0 V, but operational specifications are guaranteed only from 1.8 V to 5.5 V. Exceeding 5.5 V may cause permanent damage or parametric shift, and operation above 6.0 V violates absolute maximum ratings per Document Number 73320. Always maintain V+ within 1.8–5.5 V for compliant functionality of DG3537DB-T5-E1.
Does DG3537DB-T5-E1 support rail-to-rail analog signal switching?
Yes, DG3537DB-T5-E1 supports full rail-to-rail analog signal switching: its analog terminals (COM, NO, NC) operate from 0 V to V+ across the entire 1.8–5.5 V supply range. This capability is confirmed in the "Analog Signal Range" specification (0 V to V+) and functional block diagram, enabling undistorted passage of audio, video, and USB signals without clipping - a core design feature of DG3537DB-T5-E1.
What is the logic polarity of the control inputs on DG3537DB-T5-E1?
The control inputs (IN1 and IN2) of DG3537DB-T5-E1 are active-low: applying logic low (≤ 0.5 V at V+ = 3 V) closes the NO switch (connects NO to COM) and opens the NC path; logic high (≥ 1.4 V at V+ = 3 V) reverses the state. This complementary behavior is defined in the Truth Table and functional diagrams, and applies identically to both channels of DG3537DB-T5-E1.
Is DG3537DB-T5-E1 RoHS-compliant and halogen-free?
Yes, DG3537DB-T5-E1 is RoHS-compliant per Directive 2011/65/EU and halogen-free per JEDEC JS709A. The "-E1" suffix explicitly denotes lead-free Sn/Ag/Cu bump terminations, and Vishay documentation (Document Number 73320 and 91000) certifies compliance. These environmental attributes are integral to DG3537DB-T5-E1's qualification for consumer electronics markets requiring strict material restrictions.
Can DG3537DB-T5-E1 be used in USB 2.0 applications?
Yes, DG3537DB-T5-E1 is qualified for USB 2.0 data switching: its 360 MHz −3 dB bandwidth exceeds the 240 MHz fundamental frequency of 480 Mbps signaling, and measured crosstalk (−113 dB) and off-isolation (−78.5 dB at 1 MHz) meet signal integrity requirements for full-speed USB. Verified performance in USB paths is cited in Applications and supported by dynamic test circuits - confirming DG3537DB-T5-E1's suitability for this use case.
