Product details
Overview
DG2733EDN-T1-GE4 from Vishay Siliconix is a low-voltage dual SPDT analog switch IC designed for high-fidelity signal routing in portable systems. It operates from 1.65 V to 5.5 V single supply, delivers 0.3 Ω typical on-resistance at 5 V, guarantees break-before-make switching, and features an enable (EN) pin for system-level power control - used in audio/video multiplexing and battery-powered instrumentation.
For engineers reviewing the DG2733EDN-T1-GE4 datasheet, DG2733EDN-T1-GE4 pinout, DG2733EDN-T1-GE4 application, or DG2733EDN-T1-GE4 equivalent, key selection criteria include its 55 ns turn-on time at 2.7 V, ±300 mA continuous current rating per channel, EN-controlled dual-switch activation, and DFN-10 package compatibility with space-constrained PCB layouts.
Technical Context
The DG2733EDN-T1-GE4 integrates two independent SPDT switches sharing a common enable input (EN), unlike the DG2535E's dual independent control pins. Its CMOS architecture ensures bidirectional conduction within rail-to-rail analog voltage range and guarantees break-before-make timing of ≤15 ns.
It uses Vishay's sub-micron low-voltage process, delivering >400 mA latch-up immunity per JESD78A and 5 kV HBM ESD protection. Logic inputs are 1.65 V compatible across full 1.65–5.5 V supply range, enabling direct interfacing with 1.8 V/2.5 V/3.3 V MCUs without level shifting.
Key Specifications

| Supply Range | 1.65 V to 5.5 V single supply - supports Li-ion, USB, and low-power MCU rails without external regulators |
| On-Resistance (RDS(on)) | 0.3 Ω typ. at V+ = 5 V - minimizes signal attenuation and distortion in audio and sensor paths |
| Turn-On Time (tON) | 55 ns at 2.7 V - enables fast channel switching in data acquisition and ATE applications |
| Break-Before-Make | Guaranteed ≤15 ns - prevents momentary shorting during signal path transitions |
| Leakage Current (off) | ±100 nA max at +85 °C - preserves signal integrity in high-impedance sensor front-ends |
| Logic Compatibility | 1.65 V input threshold - interoperable with 1.8 V I/O domains without level shifters |
| ESD Rating | 5000 V HBM - enhances robustness in handheld and field-deployable equipment |
Pinout & Package
DG2733EDN-T1-GE4 is housed in a lead-free, thermally enhanced 10-lead DFN package (3 mm × 3 mm, 0.5 mm pitch) with exposed thermal pad. The package supports reflow soldering and provides low thermal resistance for sustained 300 mA channel operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NO2) | Normally Open terminal of Switch 2 | Signal output path activated when IN = 1 and EN = 1; clamped to V+ if overvoltage occurs |
| 2 (COM2) | Common terminal of Switch 2 | Bidirectional analog node connecting to NO2 or NC2 based on logic state; supports rail-to-rail signal swing |
| 3 (EN) | Enable input | High-active logic control: device disabled (all switches open) when EN = 0, regardless of IN state |
| 4 (NC2) | Normally Closed terminal of Switch 2 | Default signal path when IN = 0 and EN = 1; internally disconnected when EN = 0 |
| 5 (GND) | Ground reference | Return path for logic and analog signals; must be low-impedance for noise-sensitive applications |
| 6 (NC1) | Normally Closed terminal of Switch 1 | Default path for Switch 1; isolated when EN = 0 or IN = 1 |
| 7 (IN) | Control input for both switches | Single logic input toggles both SPDTs simultaneously - simplifies MCU GPIO usage |
| 8 (COM1) | Common terminal of Switch 1 | Primary analog interface point for Switch 1; matched RDS(on) and capacitance to COM2 |
| 9 (NO1) | Normally Open terminal of Switch 1 | Activated path for Switch 1 when IN = 1 and EN = 1; identical electrical specs to NO2 |
| 10 (V+) | Positive supply | Power rail for analog and digital circuitry; decoupling capacitor required within 1 cm for stable switching |
Key Features
| Feature | Design Value |
|---|---|
| Enable-controlled dual switching | Single EN pin globally enables/disables both SPDTs - reduces MCU pin count and eliminates race conditions |
| Rail-to-rail analog operation | Signals swing from GND to V+ without clipping - preserves dynamic range in audio and sensor interfaces |
| Matched on-resistance | ΔRON ≤ 0.08 Ω between channels - critical for balanced differential signal routing and precision instrumentation |
| Low charge injection | Typical <1 pC - prevents voltage glitches in sample-and-hold and ADC front-end circuits |
| High off-isolation | −70 dB at 100 kHz - suppresses crosstalk between active and inactive signal paths in multi-channel systems |

FAQ
What is the maximum analog signal voltage range supported by the DG2733EDN-T1-GE4?
The DG2733EDN-T1-GE4 supports analog signals from GND to V+, i.e., rail-to-rail operation. With V+ ranging from 1.65 V to 5.5 V, the analog input/output range dynamically tracks the supply rail. Signals exceeding V+ + 0.3 V or falling below −0.3 V relative to GND are clamped by internal diodes - so the absolute maximum analog voltage is limited to (V+ + 0.3 V) per the Absolute Maximum Ratings table in the DG2733EDN-T1-GE4 datasheet.
Does the DG2733EDN-T1-GE4 require external pull-up or pull-down resistors on the EN or IN pins?
No, the DG2733EDN-T1-GE4 does not require external biasing on EN or IN. Its CMOS inputs have leakage current ≤±1 μA across temperature, and logic thresholds are defined at 1.65 V (min high) and 0.4 V (max low) for 3 V supply - ensuring clean switching with direct MCU GPIO drive. However, floating inputs must be avoided: EN should be tied high or low via MCU output or hard-wired resistor to prevent unintended enable/disable states in the DG2733EDN-T1-GE4.
Can the DG2733EDN-T1-GE4 be used to switch differential analog signals such as those from an RS-422 receiver?
Yes, the DG2733EDN-T1-GE4 can route differential pairs if both lines are switched through matched channels (e.g., COM1/NO1 for one polarity, COM2/NO2 for the other). Its matched on-resistance (ΔRON ≤ 0.08 Ω) and symmetrical capacitance (CNO(on) = CNC(on) = 120 pF) preserve phase balance. However, it is not a dedicated differential switch - common-mode voltage must remain within GND to V+, and slew rate limitations apply above 120 MHz. For high-speed differential protocols, verify eye diagram integrity using the DG2733EDN-T1-GE4's 120 MHz bandwidth and 55 ns tON.
What thermal considerations apply to the DG2733EDN-T1-GE4 in continuous 300 mA operation?
At 300 mA per channel and 0.3 Ω RDS(on), power dissipation is ~27 mW per switch (I²R). The DFN-10 package has a θJA of ~120 °C/W (typical); thus, junction rise is ~3.2 °C above ambient. Derating begins above +70 °C ambient (4 mW/°C), so at +85 °C ambient, max continuous current drops to ~240 mA. Use the exposed thermal pad per Vishay's layout guidelines - minimum 4×4 mm 2-oz copper pour with ≥4 thermal vias - to maintain safe operation of the DG2733EDN-T1-GE4 under sustained load.
Is the DG2733EDN-T1-GE4 compatible with 1.8 V logic microcontrollers without level translation?
Yes, the DG2733EDN-T1-GE4 is fully compatible with 1.8 V logic. Its input high threshold is guaranteed ≥1.65 V at V+ = 3 V and ≥1.8 V at V+ = 5 V, while input low is ≤0.4 V (V+ = 3 V) or ≤0.6 V (V+ = 5 V). A 1.8 V MCU outputting 0 V / 1.8 V meets these specs directly: 1.8 V > 1.65 V satisfies VINH, and 0 V < 0.4 V satisfies VINL - enabling seamless, translation-free control of the DG2733EDN-T1-GE4 in mixed-voltage systems.
