Product details
Overview
DG2019DN-T1-E4 from Vishay Siliconix is a low-voltage, quad SPDT analog switch in QFN-16 (3 × 3 mm) package, operating from 1.8 V to 5.5 V supply, with 6 Ω on-resistance at 2.7 V, 180 MHz bandwidth, and 1.0 V logic-high threshold enabled by dedicated VL pin. It routes audio/video signals in portable instrumentation and battery-powered systems.
For engineers reviewing the DG2019DN-T1-E4 datasheet, DG2019DN-T1-E4 pinout, DG2019DN-T1-E4 application, or DG2019DN-T1-E4 equivalent, key selection criteria include its quad SPDT topology, VL-referenced 1.0 V logic compatibility, guaranteed break-before-make timing, sub-35 ns turn-off time, and 7.5 pF off-capacitance per NC/NO terminal.
Technical Context
The DG2019DN-T1-E4 integrates four independent SPDT switches controlled by a single digital input, with a dedicated VL pin enabling 1.0 V logic-high threshold when biased at 1.5 V. All channels conduct bidirectionally with matched on-resistance (ΔRON ≤ 3 Ω) and exhibit guaranteed break-before-make operation.
It uses Vishay's low-voltage submicron CMOS process to achieve 42 ns turn-on and 16 ns turn-off times at 3 V, 180 MHz small-signal bandwidth, and <10 nA channel-off leakage across –40 °C to +85 °C. An epitaxial layer prevents latch-up, and internal clamping diodes protect terminals against overvoltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | 1.8 V to 5.5 V - supports direct interface with 1.8 V, 2.7 V, 3.3 V, and 5 V logic and analog rails |
| On-Resistance (RON) | 6 Ω at V+ = 2.7 V - ensures minimal signal attenuation and voltage drop in low-level analog paths |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4619EUE+ | Higher RON (12 Ω at 3 V), no VL pin - requires ≥1.65 V logic-high input; 16-pin TSSOP only | Lacks VL-referenced low-threshold control; less suitable for 1.2 V/1.5 V host I/O domains | Select when board space permits TSSOP and system logic voltage ≥1.8 V |
| ADG732BRUZ | 32-channel, not quad SPDT; SPI interface instead of parallel control; 4 Ω RON at 3 V | Designed for high-channel-count, programmable routing - not drop-in replacement for single-control quad SPDT | Choose only for scalable, software-configurable multiplexing where pin count and control protocol allow |
Compared with MAX4619EUE+ and ADG732BRUZ, the DG2019DN-T1-E4 uniquely combines single-pin parallel control, VL-referenced 1.0 V logic compatibility, and QFN-16 packaging - enabling compact, low-voltage, low-glitch analog routing unattainable with either alternative.

FAQ
What is the function of the VL pin on the DG2019DN-T1-E4?
The VL pin on the DG2019DN-T1-E4 sets the reference voltage for the logic input threshold. When biased at 1.5 V, it enables a 1.0 V logic-high recognition level (VINH), allowing direct interfacing with 1.2 V or 1.5 V microcontroller I/O without external level shifters. This feature is integral to the DG2019DN-T1-E4's low-voltage system integration capability and is not present in the DG2018DN variant.
Does the DG2019DN-T1-E4 support bidirectional analog signal routing?
Yes, the DG2019DN-T1-E4 supports fully bidirectional analog signal routing across all COM/NO/NC paths. Its CMOS architecture ensures symmetrical on-resistance and capacitance regardless of signal direction, making it suitable for both source-to-load and load-to-source configurations in precision analog circuits. This behavior is confirmed in the device's functional description and electrical specifications for RON and CNO(on)/CNC(on).
What is the maximum analog signal voltage range supported by the DG2019DN-T1-E4?
The DG2019DN-T1-E4 supports analog signal voltages from 0 V to V+, where V+ ranges from 1.8 V to 5.5 V. Absolute maximum ratings permit signals up to (V+ + 0.3 V) on NC, NO, or COM pins, limited by internal clamping diodes. Operation outside 0 V to V+ risks increased leakage or distortion and is not characterized in the datasheet for the DG2019DN-T1-E4.
Is break-before-make timing guaranteed for all channels of the DG2019DN-T1-E4?
Yes, break-before-make timing is guaranteed for all four SPDT sections of the DG2019DN-T1-E4. The datasheet explicitly states "Brake-before-make is guaranteed for all SPDT's" and specifies a maximum break-before-make interval (td) of 1 ns under defined test conditions. This guarantee applies across the full –40 °C to +85 °C temperature range and is a design feature of the DG2019DN-T1-E4's internal control architecture.
What package type and dimensions does the DG2019DN-T1-E4 use?
The DG2019DN-T1-E4 uses a QFN-16 package measuring 3.0 mm × 3.0 mm with 0.9 mm maximum height and an exposed thermal pad. Pin pitch is 0.5 mm, and the package complies with JEDEC MO-220 standards. This compact, thermally efficient footprint is specified in Vishay document 72208 and is shared across the DG2018/DG2019 family, including the DG2019DN-T1-E4 ordering variant.
