Product details
Overview
DG2735DN-T1-E4 from Vishay Siliconix is a low-voltage, dual SPDT analog switch in miniQFN-10L package, featuring 0.6 Ω on-resistance at 2.7 V, 55 ns turn-on time, and 1.65 V to 4.3 V single-supply operation. It provides break-before-make switching for audio signal routing in portable battery-powered systems.
For engineers reviewing the DG2735DN-T1-E4 datasheet, DG2735DN-T1-E4 pinout, DG2735DN-T1-E4 application, or DG2735DN-T1-E4 equivalent, key selection criteria include logic-compatible control (1.65 V VIH), ultra-low RON flatness (0.15 Ω), ±250 mA continuous channel current, and latch-up immunity >300 mA per JESD78.
Technical Context
The DG2735DN-T1-E4 implements two independent SPDT switches with separate IN1/IN2 digital control inputs-no enable pin-ensuring fully asynchronous operation of each switch path. Its sub-micron CMOS process enables rail-to-rail analog conduction and guaranteed break-before-make timing (1–5 ns).
It operates across 1.65 V to 4.3 V supply with TTL/1.65 V logic compatibility, supporting direct interface to Li-ion single-cell systems (2.7–4.2 V). All analog terminals (COM, NO, NC) tolerate signals up to V+ + 0.3 V, clamped by internal diodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 4.3 V - supports direct one-cell Li-ion battery power without regulation |
| On-Resistance (RON) | 0.6 Ω at 2.7 V - minimizes signal attenuation and THD in audio paths |
| Turn-On Time (tON) | 55 ns at 2.7 V - enables fast channel switching in multi-source audio routing |
| Break-Before-Make Time | 1–5 ns - prevents momentary shorting between NO and NC paths during transition |
| Off-Isolation (OIRR) | −70 dB at 100 kHz - ensures high crosstalk suppression between inactive channels |
| Latch-Up Immunity | >300 mA per JESD78 - guarantees robust operation under transient overcurrent conditions |
| Logic Compatibility | VIH = 1.65 V min - interfaces directly with 1.8 V and 2.5 V MCU GPIOs without level shifters |
Pinout & Package
Package: miniQFN-10L (1.8 mm × 1.4 mm × 0.55 mm, 0.4 mm pitch), Pb-free NiPdAu terminations, MSL 1 per JEDEC J-STD-020.
| Pin | Circuit Role | Design Meaning |

| 3 | NO1 | Normally open terminal of first SPDT switch; connects to COM1 when IN1 = high |
| 4 | COM1 | Common analog terminal of first SPDT switch; bidirectional signal path |
| 5 | NC1 | Normally closed terminal of first SPDT switch; connects to COM1 when IN1 = low |
| 6 | GND | Analog/digital ground reference; must be low-impedance for signal integrity |
| 7 | NC2 | Normally closed terminal of second SPDT switch; connects to COM2 when IN2 = low |
| 8 | COM2 | Common analog terminal of second SPDT switch; bidirectional signal path |
| 9 | NO2 | Normally open terminal of second SPDT switch; connects to COM2 when IN2 = high |
| 10 | IN2 | Digital control input for second SPDT switch (active-high) |
Key Features
| Feature | Design Value |

| Guaranteed break-before-make | 1–5 ns minimum interval - eliminates signal coupling during switching in multiplexer applications |
| Low dynamic charge injection | Typical <1 pC - reduces glitch-induced pop/click in headset switching |
| High off-isolation & low crosstalk | −70 dB OIRR and −70 dB XALK at 100 kHz - maintains channel separation in multi-input audio systems |
| 1.65 V logic-compatible inputs | VIH = 1.65 V min - enables direct connection to low-voltage DSPs and microcontrollers without level translation |

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 |
|---|---|---|---|
| Texas Instruments TS5A23157DBVR | RON = 0.9 Ω at 3 V; tON = 45 ns; no guaranteed BBM; 1.65–5.5 V supply | Higher RON increases THD in high-fidelity audio; lacks BBM guarantee for critical signal isolation | Acceptable where cost sensitivity outweighs audio fidelity or BBM requirement |
| Analog Devices ADG774ACRMZ-REEL7 | RON = 2.5 Ω at 3 V; tON = 12 ns; 2.7–5.5 V supply; requires external level shifters below 2.7 V | Higher RON degrades SNR in low-level audio; incompatible with 1.8 V logic without translation | Suitable only in 3.3 V systems where speed > fidelity; not drop-in for Li-ion direct operation |
Compared with DG2735DN-T1-E4, TS5A23157DBVR trades lower cost for higher RON and unguaranteed BBM, while ADG774ACRMZ-REEL7 offers faster switching but sacrifices on-resistance performance and 1.65 V logic compatibility-making DG2735DN-T1-E4 uniquely suited for space-constrained, single-cell battery audio routing.

FAQ
What is the maximum supply voltage rating for DG2735DN-T1-E4?
The absolute maximum supply voltage (V+) for DG2735DN-T1-E4 is 5.0 V, though its specified operational range is 1.65 V to 4.3 V. Operation above 4.3 V voids parametric guarantees, and exceeding 5.0 V risks permanent damage per Absolute Maximum Ratings. DG2735DN-T1-E4 must be used within 1.65–4.3 V for guaranteed RON, switching speed, and logic compatibility.
Does DG2735DN-T1-E4 support bidirectional analog signal switching?
Yes, DG2735DN-T1-E4 supports fully bidirectional analog signal flow across all COM/NO/NC paths when the switch is on. Its CMOS architecture ensures symmetrical conduction regardless of signal direction or polarity, with identical RON and capacitance characteristics in both directions-critical for audio, sensor, and data line applications.
What is the logic polarity of the control inputs on DG2735DN-T1-E4?
The IN1 and IN2 inputs of DG2735DN-T1-E4 are active-high: applying a logic high (≥1.65 V) connects COMx to NOx, while a logic low (≤0.4 V) connects COMx to NCx. There is no enable pin-each switch operates independently based solely on its dedicated INx signal, unlike the DG2736 variant which uses an EN pin.
Is DG2735DN-T1-E4 compatible with 1.8 V microcontroller GPIOs?
Yes, DG2735DN-T1-E4 is fully compatible with 1.8 V microcontrollers: its VIH threshold is guaranteed ≤1.65 V and VIL ≤0.4 V across −40 °C to +85 °C, ensuring reliable recognition of 1.8 V logic highs and lows without external level shifting-enabling direct interface to modern low-power MCUs and DSPs.
What package type and lead finish does DG2735DN-T1-E4 use?
DG2735DN-T1-E4 uses the miniQFN-10L package (1.8 mm × 1.4 mm × 0.55 mm, 0.4 mm pitch) with nickel-palladium-gold (NiPdAu) lead finish, denoted by the "-E4" suffix. This Pb-free termination meets JEDEC reflow standards and MSL Level 1 requirements, supporting lead-free assembly without moisture sensitivity concerns.
