Product details

Overview

DG2736DN-T1-E4 from Vishay Siliconix is a low-voltage dual SPDT analog switch in miniQFN-10L package, designed for high-fidelity audio/video signal routing in portable systems. It operates from 1.65 V to 4.3 V single supply, delivers 0.6 Ω on-resistance at 2.7 V, guarantees break-before-make switching, and features an enable (EN) pin for global channel control - ideal for speaker/headset switching in battery-powered handheld devices.

For engineers reviewing the DG2736DN-T1-E4 datasheet, DG2736DN-T1-E4 pinout, DG2736DN-T1-E4 application, or DG2736DN-T1-E4 equivalent, key selection criteria include its 1.65 V logic compatibility, 55 ns turn-on time at 2.7 V, ±250 mA continuous current rating per channel, EN-controlled high-impedance state, and miniQFN footprint optimized for space-constrained PCB layouts.

Technical Context

The DG2736DN-T1-E4 integrates two independent SPDT switches sharing a common enable input (EN), placing all channels in high-impedance mode when EN = high. Its sub-micron CMOS process ensures latch-up immunity >300 mA per JESD78 and supports bidirectional analog signal conduction within rail-to-rail voltage range.

Switching is controlled by digital logic applied to IN1/IN2 pins, with EN overriding individual controls. Break-before-make timing is guaranteed across temperature (−40 °C to +85 °C), and off-isolation exceeds −70 dB at 100 kHz - critical for minimizing crosstalk in multi-channel audio paths.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	1.65 V to 4.3 V - enables direct one-cell Li-ion battery operation without level-shifting.
On-Resistance (R_ON)	0.6 Ω at 2.7 V - minimizes signal attenuation and THD in audio paths.
Turn-On Time (t_ON)	55 ns at 2.7 V - supports fast channel switching in real-time audio routing.
Enable Turn-Off Time (t_OFF(EN))	40 ns at 2.7 V - ensures rapid system-level power gating of both SPDT sections.
Off-Isolation (OIRR)	−70 dB at 100 kHz - suppresses inter-channel leakage in multi-source audio systems.
Channel Leakage Current	±10 nA max at full temp range - preserves signal integrity in high-impedance sensor/audio interfaces.
Logic Compatibility	1.65 V input high threshold - interoperates directly with low-voltage DSPs and MCUs.

3	NO1	Normally open terminal of first SPDT; connects to COM1 when IN1 = high.
4	COM1	Common analog node of first SPDT; bidirectional signal path between NO1 and NC1.
5	NC1	Normally closed terminal of first SPDT; connects to COM1 when IN1 = low.
6	GND	Analog/digital ground reference; must be low-impedance for noise-sensitive audio routing.
7	NC2	Normally closed terminal of second SPDT; connects to COM2 when IN2 = low.
8	COM2	Common analog node of second SPDT; shared signal interface for dual-path routing.
9	NO2	Normally open terminal of second SPDT; connects to COM2 when IN2 = high.
10	EN	Global enable input; high = all switches in high-Z; low = IN1/IN2 control active.

Key Features

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 TS5A23157DCUR	0.9 Ω R_ON at 3 V; no EN pin; separate IN1/IN2 only.	Lacks global enable - requires additional GPIO or logic for system-level shutdown.	Select when EN functionality is unnecessary and cost sensitivity outweighs R_ON penalty.
Analog Devices ADG884BRMZ	0.55 Ω R_ON at 3 V; 10-lead MSOP package; no EN pin.	Larger 3 mm × 3 mm footprint; lacks EN-driven high-Z mode for power-aware designs.	Choose for lowest R_ON where board space permits larger package and EN is not required.

Compared with TS5A23157DCUR and ADG884BRMZ, the DG2736DN-T1-E4 uniquely combines sub-0.6 Ω on-resistance, integrated EN control, and ultra-compact miniQFN-10L packaging - making it optimal for space- and power-constrained portable audio systems requiring coordinated channel disable.

FAQ

What is the maximum supply voltage rating for DG2736DN-T1-E4?

The DG2736DN-T1-E4 has an absolute maximum supply voltage (V+) of 5 V, but its specified operational range is 1.65 V to 4.3 V. Operating above 4.3 V may compromise parametric performance and reliability, and is not guaranteed per the datasheet. For robust long-term use in portable systems, maintain V+ within the 1.65–4.3 V window - especially important when powered directly from a single Li-ion cell.

Does DG2736DN-T1-E4 support bidirectional analog signal switching?

Yes, the DG2736DN-T1-E4 supports fully bidirectional analog signal conduction on all switched paths (NO1/COM1/NC1 and NO2/COM2/NC2). When enabled, the switch conducts equally well in either direction within the power rail limits (0 V to V+), with matched on-resistance and capacitance characteristics - a key requirement for audio line-level and sensor signal routing where signal polarity is undefined.

How does the EN pin function in DG2736DN-T1-E4?

In the DG2736DN-T1-E4, the EN pin provides global enable/disable control: when EN = high, both SPDT sections enter high-impedance state regardless of IN1/IN2 logic levels; when EN = low, IN1 and IN2 regain control of their respective switches. This allows system-level power gating without modifying individual channel logic - critical for reducing standby current in always-on portable devices.

What is the guaranteed break-before-make interval for DG2736DN-T1-E4?

The DG2736DN-T1-E4 guarantees break-before-make operation with a minimum t_BBM of 1 ns (typical 5 ns) at V+ = 3.6 V, measured under RL = 50 Ω and CL = 35 pF conditions. This ensures no overlap between NO and NC connections during state transitions - preventing short-circuits in audio paths and protecting downstream amplifiers from transient current spikes.

Is DG2736DN-T1-E4 compatible with 1.8 V logic systems?

Yes, the DG2736DN-T1-E4 is fully compatible with 1.8 V logic systems: its input high voltage (V_INH) is guaranteed ≥1.65 V over the full −40 °C to +85 °C range, and input low voltage (V_INL) is ≤0.4 V. This allows direct connection to 1.8 V GPIOs of modern application processors and microcontrollers without level-shifting circuitry - simplifying design and reducing component count.
