Product details
Overview
DG2739DN-T1-E4 from Vishay Siliconix is a dual SPST analog switch in miniQFN-8 package, designed for high-speed signal routing in portable electronics. It delivers 6 Ω typical on-resistance at 3 V, 720 MHz -3 dB bandwidth, and ±300 mA latch-up immunity, enabling bidirectional signal switching up to VCC in battery-powered audio and data paths.
For engineers reviewing the DG2739DN-T1-E4 datasheet, DG2739DN-T1-E4 pinout, DG2739DN-T1-E4 application, or DG2739DN-T1-E4 equivalent, key selection criteria include its break-before-make timing (6 ns), -48 dB crosstalk at 240 MHz, and 2.3 V to 4.3 V single-supply operation with ultra-low 1 µA supply current.
Technical Context
The DG2739DN-T1-E4 implements independent dual SPST switching with separate digital control inputs (VIN1, VIN2) enabling asynchronous channel activation. Its sub-micron CMOS process ensures low RON flatness (4 Ω max) and minimal charge injection (10.4 pC), critical for precision sampling and low-distortion signal paths.
It features break-before-make timing (6 ns typ.) to prevent signal shorting during channel transitions, and supports rail-to-rail analog signals (0 V to V+) with 4.4 pF source-off capacitance and 3.8 pF drain-off capacitance - optimized for RF and high-frequency data acquisition systems.

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 |
|---|---|---|---|
| MAX4677ETA+ | Higher RON (12 Ω typ. at 3 V), wider supply (1.8–5.5 V), no break-before-make guarantee | Lower bandwidth (300 MHz), higher crosstalk (-35 dB at 240 MHz) | Choose for broader supply compatibility where ultra-low RON and RF performance are secondary |
| ADG779BRMZ | Similar RON (6.5 Ω typ.), but only single SPST per package; requires two devices for dual function | No integrated break-before-make; higher 15 ns tBBM vs. DG2739's 6 ns | Choose when board layout allows discrete channel placement and timing margin permits longer tBBM |
Compared with MAX4677ETA+ and ADG779BRMZ, the DG2739DN-T1-E4 provides superior RF performance (720 MHz bandwidth, -48 dB crosstalk), guaranteed break-before-make timing, and true dual-channel integration in a single 1.4 mm² package - making it optimal for space-constrained, high-frequency portable designs.

FAQ
What is the maximum analog signal voltage supported by the DG2739DN-T1-E4?
The DG2739DN-T1-E4 supports analog signals from 0 V to V+, meaning it can pass rail-to-rail voltages up to the positive supply rail (up to 4.3 V). Internal clamping diodes limit signals exceeding V+ to prevent damage, but sustained operation above V+ must be avoided per absolute maximum ratings.
Does the DG2739DN-T1-E4 support break-before-make switching between its two channels?
Yes, the DG2739DN-T1-E4 guarantees break-before-make timing of 6 ns typical, as confirmed in the datasheet's Figure 2 and specifications table. This ensures that S1/D1 and S2/D2 channels never conduct simultaneously, eliminating risk of signal shorting during channel transitions - a key requirement for reliable multiplexing.
What is the thermal derating behavior of the DG2739DN-T1-E4 above 70 °C?
The DG2739DN-T1-E4 requires derating of 2.4 mW/°C above 70 °C ambient temperature, as specified in Note c of the Absolute Maximum Ratings table. At 85 °C, its maximum allowable power dissipation drops from 190 mW (at ≤70 °C) to approximately 154 mW, necessitating careful thermal design in high-temperature environments.
How does the DG2739DN-T1-E4 handle ESD events in real-world PCB layouts?
The DG2739DN-T1-E4 exceeds 5 kV HBM ESD rating per JESD22-A114, verified through standardized testing. In practice, this means it withstands typical handling and board-level ESD events without latch-up or parameter shift - provided standard PCB practices (ground plane, short traces, decoupling) are followed per Vishay's layout recommendations.
Can the DG2739DN-T1-E4 operate reliably at 2.3 V supply voltage?
Yes, the DG2739DN-T1-E4 is fully specified down to 2.3 V supply voltage, with guaranteed performance including 6 Ω typical RON, 23 ns tON, and proper logic threshold levels (VINH = 1.3 V min). This makes it suitable for direct integration with deeply discharged Li-ion batteries or low-voltage microcontroller I/O.
