Product details
Overview
DG454EY-T1-E3 from Vishay Siliconix is a high-voltage quad SPST analog switch with normally closed (NC) 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 and video switching in industrial test equipment and communications interfaces.
For engineers reviewing the DG454EY-T1-E3 datasheet, DG454EY-T1-E3 pinout, DG454EY-T1-E3 application, or DG454EY-T1-E3 equivalent, key selection criteria include its 80 ns turn-on time, 0.2 Ω on-resistance flatness, TTL/CMOS-compatible logic thresholds, absence of VL supply requirement, and compatibility with ±5 V, ±15 V, or 12 V single-supply operation.
Technical Context
The DG454EY-T1-E3 implements four independent CMOS transmission gates with complementary control architecture-logic '0' closes all switches, logic '1' opens them. Its rail-to-rail analog conduction supports symmetric dual-supply (±5 V to ±15 V) or unipolar (12 V) operation without level-shifting circuitry.
Internal ESD protection (2 kV HBM), charge injection as low as 1 pC at 12 V supply, and guaranteed off-isolation of –60 dB at 1 MHz ensure robust performance in sensitive data acquisition and automatic test equipment where signal integrity and channel crosstalk are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance | 4 Ω typical - enables minimal insertion loss and voltage drop in low-level analog paths |
| Analog signal range | ±15 V - supports full-rail signal handling across dual supplies without clipping |
| Supply voltage max | 44 V - allows safe operation with transient margins in industrial power domains |
| Turn-on time | 80 ns - ensures fast multiplexing in high-speed sampling and video sync applications |
| On-resistance flatness | 0.2 Ω typical - maintains consistent gain and THD < 0.04% across audio band (20 Hz–20 kHz) |
| Logic threshold | 0.8 V / 2.4 V - guarantees interoperability with standard TTL and CMOS drivers without interface logic |
| ESD rating | 2 kV HBM - provides built-in protection against handling-induced transients during PCB assembly |
Pinout & Package
Package: 16-pin narrow SOIC (SOIC-16), JEDEC MS-012 compliant, body dimensions 9.9 mm × 3.9 mm × 1.45 mm, lead pitch 1.27 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN1) | Digital control input for SW1 | Active-low logic: '0' closes SW1, '1' opens SW1 (NC function) |
| 2 (IN2) | Digital control input for SW2 | Active-low logic: '0' closes SW2, '1' opens SW2 |
| 3 (D1) | Drain terminal of SW1 | Bidirectional analog node; connects to load or signal source when switch is closed |
| 4 (D2) | Drain terminal of SW2 | Bidirectional analog node; supports rail-to-rail signal swing up to ±15 V |
| 5 (S1) | Source terminal of SW1 | Paired with D1; interchangeable role depending on signal direction |

| 8 (V+) | Positive supply rail | Supports up to +16.5 V; defines upper analog voltage limit |
| 9 (GND) | Ground reference | Return path for digital logic and substrate bias; separate from analog ground in mixed-signal layouts |
| 10 (N.C.) | No connection | Internally unconnected; must remain floating or tied to GND per layout best practice |
| 11 (S4) | Source terminal of SW4 | Completes fourth NC switch pair; matches S1/S2/S3 functionality |
| 12 (S3) | Source terminal of SW3 | Third NC switch source; identical electrical behavior to S1 and S2 |
| 13 (D4) | Drain terminal of SW4 | Fourth NC switch drain; fully symmetrical with D1–D3 |
| 14 (D3) | Drain terminal of SW3 | Third NC switch drain; supports same current (100 mA continuous) and voltage ratings |
| 15 (IN4) | Digital control input for SW4 | Active-low logic input; synchronized timing with IN1–IN3 for simultaneous switching |
| 16 (IN3) | Digital control input for SW3 | Enables independent or grouped control of all four NC switches |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4544ESE+ | Lower on-resistance (2.5 Ω typ), but only rated to ±12 V analog range and requires VL supply | Better for low-voltage portable instruments; unsuitable for ±15 V industrial signal chains | Select when lower RON outweighs supply flexibility and voltage range needs |
| ADG1414BRUZ | Higher voltage rating (±20 V), 3.8 Ω RON, but 16-lead TSSOP only-no SOIC-16 option | Preferred for new high-density PCBs; incompatible with existing SOIC-16 footprints | Choose for new designs prioritizing thermal performance and higher breakdown margin |
Compared with MAX4544ESE+ and ADG1414BRUZ, DG454EY-T1-E3 uniquely balances SOIC-16 footprint compatibility, ±15 V signal support, and no-VL simplicity-making it optimal for drop-in upgrades of legacy test equipment and industrial controllers where board space and supply architecture are constrained.

FAQ
What is the maximum analog signal voltage supported by DG454EY-T1-E3?
DG454EY-T1-E3 supports an analog signal range of ±15 V when operated with dual ±15 V supplies, and up to 12 V with a single 12 V supply. Its absolute maximum rating is 44 V between V+ and V−, allowing safe operation with transient headroom in industrial environments. This makes DG454EY-T1-E3 suitable for applications demanding full-rail signal handling without external clamping.
Does DG454EY-T1-E3 require a separate VL logic supply?
No, DG454EY-T1-E3 does not require a VL supply. Unlike earlier analog switches such as the DG411, it derives logic level referencing directly from V+ and V−, simplifying power architecture. Digital inputs operate with standard TTL/CMOS thresholds (0.8 V low, 2.4 V high) across the full temperature range, making DG454EY-T1-E3 compatible with 3.3 V or 5 V microcontrollers without level shifters.
How does the DG454EY-T1-E3 differ from DG455EY-T1-E3 and DG456EY-T1-E3?
DG454EY-T1-E3 is a quad normally closed (NC) switch, while DG455EY-T1-E3 is quad normally open (NO) with inverted logic control, and DG456EY-T1-E3 integrates two NC and two NO switches in one package. All three share identical pinouts, on-resistance, and supply specifications-but differ strictly in default switch state and truth table behavior. DG454EY-T1-E3 turns switches ON with logic low, making it ideal for fail-safe signal path closure.
What is the thermal resistance of DG454EY-T1-E3 in its SOIC-16 package?
The 16-pin narrow SOIC package of DG454EY-T1-E3 has a thermal resistance (θJA) of 125 °C/W, measured under standard JEDEC conditions. At 25 °C ambient and full 600 mW power dissipation, this results in a junction temperature rise of 75 °C-well within the +125 °C maximum rating. Derating begins above +75 °C at 8 mW/°C, ensuring reliable operation in enclosed industrial enclosures.
Can DG454EY-T1-E3 be used in audio applications requiring low total harmonic distortion?
Yes, DG454EY-T1-E3 delivers 0.04% THD at 5 VRMS across 20 Hz–20 kHz with 600 Ω load, validated per specification sheet. This performance stems from its 4 Ω typical on-resistance and 0.2 Ω flatness, which minimize nonlinear voltage-dependent losses. Combined with low charge injection (1 pC at 12 V), DG454EY-T1-E3 is qualified for professional audio routing, microphone switching, and studio-grade signal conditioning where spectral purity is critical.
