Product details
Overview
DG2733DN-T1-E4 from Vishay Siliconix is a low-voltage, dual SPDT analog switch with 0.29 Ω typical on-resistance at 4.3 V supply, 79 ns turn-on time, and enable-controlled operation. It functions as a bidirectional signal routing device in portable audio systems, supporting rail-to-rail analog signal switching up to the supply voltage with guaranteed break-before-make timing.
For engineers reviewing the DG2733DN-T1-E4 datasheet, DG2733DN-T1-E4 pinout, DG2733DN-T1-E4 application, or DG2733DN-T1-E4 equivalent, key selection criteria include its 1.6 V logic compatibility, sub-0.5 Ω on-resistance across 1.6–4.3 V supply range, EN-pin activation, and DFN-10 package suitability for space-constrained battery-powered designs.
Technical Context
The DG2733DN-T1-E4 implements dual independent SPDT switches using sub-micron CMOS process, with a dedicated EN pin enabling synchronous control of both channels under high-logic assertion. Its internal architecture guarantees break-before-make timing (≤10 ns) and supports bidirectional analog signal flow without polarity restriction.
It operates over 1.6–4.3 V single supply, maintains TTL/1.6-V logic compatibility, and delivers <10 pA off-leakage at 85°C. Latch-up immunity exceeds 300 mA per JESD78, and all I/O pins tolerate overvoltage clamping to V+ + 0.3 V via integrated diodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | 1.6 V to 4.3 V single supply - enables direct one-cell Li-ion battery operation without regulation |
| On-Resistance (rON) | 0.29 Ω typ @ 4.3 V - minimizes signal attenuation and power loss in audio path routing |
| Turn-On Time (tON) | 79 ns typ @ 4.3 V - supports fast channel switching in headset detection and audio multiplexing |
| Off-Leakage Current | ±20 nA max @ 4.3 V - ensures minimal DC error in precision sensor or microphone bias networks |
| Enable Propagation Delay | EN input controls both switches simultaneously - eliminates sequencing complexity in dual-path systems |
| Logic Compatibility | 1.6-V input threshold - interfaces directly with low-voltage DSPs and ARM Cortex-M MCUs |
| Break-Before-Make | Guaranteed ≤10 ns - prevents momentary short-circuit during signal re-routing |
Pinout & Package
Package: 10-pin DFN (3 mm × 3 mm, 0.5 mm pitch), lead (Pb)-free with nickel-palladium-gold termination (-E4 suffix), MSL 1, JEDEC-compliant reflow profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 8 | NO1, COM1, NC1, NO2, COM2, NC2, IN1, IN2 | Switch terminals and digital control inputs for two independent SPDT channels |
| 9 | GND | Ground reference for analog and digital domains - must be low-impedance connection |
| 10 | V+ | Single positive supply rail - powers analog switch core and level-shifting logic |
| - | EN | Enable control is implemented via Pin 1 (IN1) and Pin 2 (IN2) logic combination per truth table; no dedicated EN pin - DG2733 uses dual-control with EN function encoded in logic states |
Key Features
| Feature | Design Value |
|---|---|
| Low on-resistance matching | ΔrON ≤ 0.06 Ω - ensures consistent gain and phase response between dual audio paths |
| Rail-to-rail analog signal handling | Supports VCOM, VNO, VNC from 0 V to V+ - enables full-swing audio and sensor signal routing |
| Charge injection | 9 pC typ - limits glitch amplitude in DC-coupled microphone or sensor front-ends |
| Off-isolation | –75 dB @ 100 kHz - suppresses crosstalk between active and inactive audio channels |
| Latch-up immunity | >300 mA per JESD78 - withstands transient overcurrent events in handheld ESD-prone environments |

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 |
|---|---|---|---|
| MAX4683ETA+ | Higher rON (0.6 Ω @ 3 V), no EN pin, MSOP-8 package | Lacks enable control; requires external logic for synchronized dual-channel operation | Prefer DG2733DN-T1-E4 when EN functionality and lower on-resistance are required in DFN footprint |
| TS5A23157DCUR | 0.55 Ω rON @ 3.3 V, 1.65–5.5 V supply, 10-pin VSSOP | Wider supply range but higher on-resistance and larger package; no guaranteed break-before-make | Choose DG2733DN-T1-E4 for battery-powered audio where <0.3 Ω rON and BBM timing are critical |
Compared with MAX4683ETA+ and TS5A23157DCUR, DG2733DN-T1-E4 offers the lowest on-resistance in its voltage class, integrated enable logic for dual-channel coordination, and guaranteed break-before-make - making it optimal for high-fidelity, low-noise portable audio routing where signal integrity and layout density are prioritized.

FAQ
What is the maximum supply voltage rating for DG2733DN-T1-E4?
The absolute maximum supply voltage for DG2733DN-T1-E4 is 5.0 V referenced to GND, though functional operation is specified only up to 4.3 V. Operating beyond 4.3 V may degrade on-resistance performance and increase leakage; sustained use above 4.3 V voids parametric guarantees and risks reliability. Always refer to the Absolute Maximum Ratings table in the official Vishay datasheet (Document Number 73484) for derating guidance.
Does DG2733DN-T1-E4 have a dedicated enable pin?
No, DG2733DN-T1-E4 does not have a physical EN pin. Instead, its enable functionality is implemented through logic-level control of the two digital inputs (IN1 and IN2), as defined in the truth table: when both IN1 and IN2 are high (logic 1), both switches are enabled (ON); any other combination disables both channels. This architecture simplifies PCB routing by eliminating a separate enable net while maintaining synchronized dual-channel control.
What is the on-resistance matching between channels in DG2733DN-T1-E4?
DG2733DN-T1-E4 specifies ΔrON ≤ 0.06 Ω (typical 0.03 Ω) across VCOM = 0.9–2.5 V and V+ = 4.3 V, measured at 100 mA load. This tight matching ensures minimal gain and phase skew between the two SPDT channels - critical for stereo audio routing, differential sensor multiplexing, and matched signal path applications where channel balance directly impacts system accuracy.
Can DG2733DN-T1-E4 operate from a single 1.8 V supply?
Yes, DG2733DN-T1-E4 is fully operational at 1.8 V supply, with verified specifications including 1.2 Ω max on-resistance, 140 ns max turn-on time, and guaranteed break-before-make. Its 1.6 V logic-compatible inputs allow direct interfacing with 1.8 V microcontrollers and baseband processors without level shifting - making DG2733DN-T1-E4 suitable for ultra-low-power IoT and wearables where supply headroom is constrained.
Is DG2733DN-T1-E4 RoHS compliant and lead-free?
Yes, DG2733DN-T1-E4 is RoHS compliant and lead-free, with nickel-palladium-gold (NiPdAu) termination on its DFN-10 package, indicated by the "-E4" suffix. It meets all JEDEC standards for reflow soldering and moisture sensitivity level (MSL) 1, and has been qualified per JESD78 for >300 mA latch-up immunity - confirming robustness in automated assembly and field operation.
