Product details
Overview
DG454EQ-T1-E3 from Vishay Siliconix is a high-voltage quad SPST CMOS analog switch with 4 Ω typical on-resistance, 44 V supply rating, and ±15 V analog signal range-designed for low-distortion audio switching, video routing, and precision data acquisition systems.
For engineers reviewing the DG454EQ-T1-E3 datasheet, DG454EQ-T1-E3 pinout, DG454EQ-T1-E3 application, or DG454EQ-T1-E3 equivalent, key selection criteria include on-resistance flatness (0.2 Ω typ), fast switching (tON = 80 ns, tOFF = 60 ns), TTL/CMOS logic compatibility, and dual-supply operation at ±5 V, ±15 V, or single 12 V.
Technical Context
The DG454EQ-T1-E3 implements four independent normally-closed (NC) SPST switches with bidirectional conduction, rail-to-rail analog signal handling up to ±15 V, and no VL supply requirement-unlike legacy DG411-series predecessors. Its digital control inputs feature fixed 0.8 V / 2.4 V TTL/CMOS thresholds across all operating voltages.
Switching performance is characterized under multiple supply configurations: tON/tOFF values are specified at ±15 V (80/60 ns), ±5 V (170/66 ns), and +12 V (132/61 ns); on-resistance remains ≤5.3 Ω (typ) at ±15 V and ≤8.1 Ω (typ) at +12 V, with flatness ≤0.5 Ω over full signal range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 4 Ω typical at ±15 V - ensures minimal insertion loss and signal attenuation in audio/video paths |
| On-resistance flatness | 0.2 Ω typical - maintains consistent gain and THD < 0.04 % across full ±10 V signal swing |
| Supply voltage range | ±5 V, ±15 V, or +12 V - supports flexible system-level power architecture without auxiliary VL rail |
| Switching speed | tON = 80 ns, tOFF = 60 ns at ±15 V - enables clean video signal routing up to ~10 MHz bandwidth |
| Analog signal range | ±15 V - allows direct interfacing with industrial sensor outputs and op-amp stages without level-shifting |
| Continuous current rating | 100 mA per channel - supports relay-replacement in moderate-power test equipment and signal conditioning |
| ESD protection | 2 kV HBM - provides robust handling during board assembly and field service without external protection |
Pinout & Package
Package: 16-pin TSSOP (JEDEC MS-012, body size 5.0 × 4.4 mm, 0.65 mm pitch). Pin-compatible with SOIC-16 variant DG454EY-T1-E3 but with reduced footprint and thermal resistance (178 °C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 (IN1–IN4) | Digital control input | Active-low logic for NC switches; 0.8 V/2.4 V thresholds ensure reliable TTL/CMOS drive without level shifters |
| 5, 6, 13, 14 (S1–S4) | Source terminal | Common analog node for each switch; connects to signal source or system ground reference |
| 7, 8, 11, 12 (D1–D4) | Drain terminal | Output node; bidirectional conduction allows S/D interchangeability in layout |
| 9 (GND) | Ground reference | Logic and substrate reference; must be low-impedance connection to minimize noise coupling |
| 10 (N.C.) | No-connect | Internally unconnected; must remain floating or tied to GND per PCB design rules |
| 15 (V−) | Negative supply rail | Supports dual-supply operation down to −15 V; required for full ±15 V analog range |
| 16 (V+) | Positive supply rail | Accepts +12 V (unipolar) or +15 V (bipolar); maximum 44 V differential between V+ and V− |
Key Features
| Feature | Design Value |
|---|---|
| No VL supply required | Eliminates need for separate logic-level supply rail-reduces BOM count and simplifies power sequencing |
| Rail-to-rail analog operation | Input signals extend from V− to V+ (±15 V), enabling direct interface with high-dynamic-range sensors and DACs |
| Low charge injection (22 pC) | Minimizes voltage glitch on sample-and-hold capacitors, critical for precision ADC front-ends |
| High off-isolation (−60 dB @ 1 MHz) | Prevents crosstalk between active and inactive channels in multi-channel audio/video multiplexers |
| Pin-compatible with DG411 series | Enables drop-in upgrade path from legacy parts while removing VL dependency and improving RON flatness |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4544ESE+ | Quad SPST NC, 4.5 Ω RON, ±15 V rating, but requires VL = 3 V to 5 V supply and has higher 100 pC charge injection | Less suitable for ultra-low-glitch sample-and-hold; requires additional power rail | Choose when existing design already includes VL rail and lower cost is prioritized over charge injection |
| ADG1414BRUZ | Quad SPST NC, 1.8 Ω RON, ±15 V rating, but 125 °C max junction temperature vs. DG454EQ-T1-E3's 125 °C ambient rating and higher 300 mA peak current | Better for high-current or extended-temperature industrial environments where lower RON justifies premium cost | Choose when <2 Ω RON is mandatory and thermal derating margin is available |
Compared with MAX4544ESE+ and ADG1414BRUZ, DG454EQ-T1-E3 offers the optimal balance of low RON flatness (0.2 Ω), zero-VL operation, and proven 125 °C ambient reliability-making it preferred for space-constrained, mixed-signal test and broadcast equipment where layout simplicity and signal fidelity are critical.

FAQ
What is the maximum analog signal voltage range supported by the DG454EQ-T1-E3?
The DG454EQ-T1-E3 supports an analog signal range of ±15 V when operated with dual ±15 V supplies, and 0 V to +12 V with a single +12 V supply. Its absolute maximum rating is 44 V between V+ and V−, and signals extending to the supply rails are fully supported without clipping or damage-enabling direct interface with high-dynamic-range sensor outputs and op-amp stages in the DG454EQ-T1-E3.
Does the DG454EQ-T1-E3 require a separate VL logic supply voltage?
No, the DG454EQ-T1-E3 does not require a VL supply. Unlike earlier DG411-series switches, it operates its digital control inputs directly from standard TTL/CMOS logic levels (0.8 V low, 2.4 V high) referenced to GND, eliminating the need for an auxiliary logic rail. This simplifies power architecture and reduces BOM count in systems using the DG454EQ-T1-E3.
What is the typical on-resistance flatness of the DG454EQ-T1-E3, and why does it matter?
The DG454EQ-T1-E3 has a typical on-resistance flatness of 0.2 Ω across the full ±10 V analog signal range. This tight flatness minimizes harmonic distortion (THD < 0.04 %) and ensures consistent gain in audio and precision measurement paths-critical for maintaining signal fidelity in professional audio mixers and high-resolution data acquisition systems using the DG454EQ-T1-E3.
Can the DG454EQ-T1-E3 be used in single-supply applications?
Yes, the DG454EQ-T1-E3 is fully specified for single-supply operation at +12 V, supporting analog signals from 0 V to +12 V. Its on-resistance remains ≤8.1 Ω (typ), switching times are 132 ns tON/61 ns tOFF, and leakage stays below ±0.5 nA-making it suitable for portable test gear and industrial controllers where only one positive rail is available for the DG454EQ-T1-E3.
How does the DG454EQ-T1-E3 compare to the DG411 in terms of pin compatibility and performance?
The DG454EQ-T1-E3 is pin-compatible with the DG411 but removes the VL supply requirement and improves key specs: on-resistance flatness is reduced from ~1.5 Ω to 0.2 Ω typ, THD drops to 0.04 %, and charge injection is cut to 22 pC. These enhancements make the DG454EQ-T1-E3 a direct, higher-performance drop-in replacement for the DG411 in existing designs without layout changes.
