Product details
Overview
DG455EY-T1-E3 from Vishay Siliconix is a high-voltage quad SPST analog switch with normally open (NO) configuration, designed for bidirectional signal routing in precision analog systems. It delivers 4 Ω typical on-resistance, ±15 V analog signal range, and 44 V supply rating - enabling low-distortion audio switching and robust video signal handling across dual (±5 V, ±15 V) or single (12 V) supply rails.
For engineers reviewing the DG455EY-T1-E3 datasheet, DG455EY-T1-E3 pinout, DG455EY-T1-E3 application, or DG455EY-T1-E3 equivalent, key selection criteria include its 80 ns turn-on time, 0.2 Ω on-resistance flatness, TTL/CMOS-compatible logic thresholds (0.8 V / 2.4 V), and absence of VL supply requirement - critical for space-constrained, high-fidelity signal path designs.
Technical Context
The DG455EY-T1-E3 implements four independent CMOS transmission gates with complementary control architecture: logic '0' enables all switches (NO function), while logic '1' disables them. Each channel supports rail-to-rail analog signals up to ±15 V with symmetrical conduction in both directions when on.
It operates fully specified across three supply configurations: ±5 V, ±15 V, and +12 V/0 V - with guaranteed performance over –40 °C to +125 °C. Internal ESD protection (2 kV HBM) and no-VL architecture eliminate auxiliary bias requirements common in legacy analog switches like the DG411/DG412 family.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance | 4 Ω typical - ensures minimal insertion loss and voltage drop in audio/video signal paths at ±10 V signal levels. |
| On-resistance flatness | 0.2 Ω typical - maintains consistent gain and linearity across full analog input range, critical for THD-sensitive applications. |
| Supply voltage rating | 44 V max (V+ to V−) - supports operation with ±15 V supplies or +12 V/0 V without derating or external clamping. |
| Turn-on/turn-off time | 80 ns / 60 ns - enables reliable switching of composite video (NTSC/PAL) and fast-sampling data acquisition signals. |
| Analog signal range | ±15 V - allows direct interfacing with industrial sensor outputs, op-amp stages, and DACs without level-shifting. |
| Logic compatibility | 0.8 V low / 2.4 V high thresholds - interoperates directly with 3.3 V and 5 V TTL/CMOS controllers without level translation. |
| ESD protection | 2 kV HBM - provides robust handling during PCB assembly and field service in non-ESD-controlled environments. |
Pinout & Package
Package: 16-pin narrow SOIC (JEDEC MS-012), 7.5 mm × 10.3 mm footprint, 1.27 mm pitch, 1.10 mm nominal height - compatible with standard SOIC reflow profiles and automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 (IN1–IN4) | Digital control input | Active-low logic inputs for SPST NO switches; logic '0' closes corresponding switch, '1' opens it. |
| 2, 6, 10, 14 (S1–S4) | Switch source terminal | Analog input/output node - bidirectional conduction when switch is on; connects to signal source or load. |
| 3, 7, 11, 15 (D1–D4) | Switch drain terminal | Analog input/output node - mirror role to Sx; forms complete transmission path with corresponding Sx pin. |
| 4 (V−) | Negative supply rail | Reference for negative analog swing; must be connected even in single-supply operation (0 V reference). |
| 8 (GND) | Ground reference | Logic ground and substrate reference; separate from analog signal return to minimize noise coupling. |
| 12 (V+) | Positive supply rail | Reference for positive analog swing; supports up to +15 V in dual mode or +12 V in unipolar mode. |
| 16 (N.C.) | No-connect | Internally unused pin - must remain unconnected per datasheet; not tied to any internal node. |
Key Features
| Feature | Design Value |
|---|---|
| No VL supply required | Eliminates need for third bias rail - simplifies power design and reduces BOM count versus DG411/DG412 family. |
| Rail-to-rail analog conduction | Supports input signals extending to V+ and V− rails - preserves full dynamic range of precision op-amps and ADC drivers. |
| Low charge injection (22 pC) | Minimizes voltage glitch at sample-hold nodes - essential for <12-bit accuracy in data acquisition front-ends. |
| High off-isolation (–60 dB) | Suppresses crosstalk between active and inactive channels at 1 MHz - maintains signal integrity in multi-channel audio routing. |
| Pin-compatible with DG411/DG412/DG413 | Enables drop-in upgrade path - retains existing PCB layout while improving on-resistance and eliminating VL dependency. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4555ESE+ | Higher on-resistance (10 Ω typ), requires VL supply, lower ESD (1 kV HBM) | Limited to lower-precision instrumentation where cost is primary constraint | Choose only if VL rail already exists and 4 Ω RON is not required |
| ADG1414BRUZ | Lower on-resistance (1.3 Ω typ), higher supply rating (±20 V), but larger TSSOP-20 package | Suitable for ultra-low-distortion medical imaging front-ends requiring tighter RON matching | Select when sub-2 Ω RON and enhanced thermal performance justify PCB area increase |
Compared with MAX4555ESE+ and ADG1414BRUZ, DG455EY-T1-E3 offers optimal balance of low on-resistance, no-VL simplicity, and SOIC-16 compactness - making it ideal for cost-sensitive, space-constrained industrial and consumer audio/video systems requiring proven reliability and broad supply flexibility.

FAQ
What is the maximum analog signal voltage range supported by DG455EY-T1-E3?
DG455EY-T1-E3 supports a ±15 V analog signal range when operated with ±15 V dual supplies, and 0 V to +12 V with single-supply configuration. Signals exceeding V+ or V− are clamped by internal diodes - forward current must be limited to rated maximums per datasheet Note a. This rail-to-rail capability makes DG455EY-T1-E3 suitable for interfacing with high-output op-amps and industrial sensors without external level-shifting circuitry.
Does DG455EY-T1-E3 require a VL supply pin like older analog switches?
No, DG455EY-T1-E3 does not require a VL supply pin. Unlike the DG411/DG412 family it replaces, DG455EY-T1-E3 integrates internal level-shifting circuitry that eliminates the need for a separate logic supply. This simplifies power design, reduces component count, and avoids potential timing skew between logic and analog domains - a key advantage confirmed in the datasheet's Features section and Ordering Information table.
What is the operating temperature range for DG455EY-T1-E3?
DG455EY-T1-E3 is rated for continuous operation from –40 °C to +125 °C, with full electrical specifications guaranteed across this range. The device uses silicon technology qualified to automotive-grade reliability standards, and thermal derating begins above +70 °C (5.6 mW/°C) per Absolute Maximum Ratings table. This extended range supports deployment in under-hood automotive modules and industrial PLCs without external cooling.
How does the DG455EY-T1-E3 differ from DG454EY-T1-E3 and DG456EY-T1-E3?
DG455EY-T1-E3 is the normally open (NO) variant: logic '0' closes all four switches. DG454EY-T1-E3 is the normally closed (NC) version (logic '0' opens switches), and DG456EY-T1-E3 combines two NC and two NO switches in one package. All three share identical pinout, on-resistance, timing, and supply specifications - only digital logic polarity and default switch state differ. This is explicitly stated in the Truth Table and Description sections of the datasheet.
Can DG455EY-T1-E3 be used in single-supply 5 V systems?
Yes, DG455EY-T1-E3 supports 5 V single-supply operation (V+ = 5 V, V− = 0 V) with verified performance: analog signal range is 0 V to 5 V, on-resistance is 11 Ω typical, and switching times are 200 ns (tON) / 96 ns (tOFF). Logic thresholds remain compatible (0.8 V low / 2.4 V high), allowing direct interface with 5 V microcontrollers. Full specifications for this condition are provided in the "Specifications for Dual Supplies" table with V+ = 5 V, V− = –5 V, and the "Specifications for Unipolar Supplies" table confirms functional operation at 5 V.
