Product details
Overview
DG455EQ-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 audio and video systems. It delivers 4 Ω typical on-resistance, ±15 V analog signal range, and operates across dual supplies (±5 V, ±15 V) or single 12 V supply - enabling low-distortion switching in test equipment and relay-replacement applications.
For engineers reviewing the DG455EQ-T1-E3 datasheet, DG455EQ-T1-E3 pinout, DG455EQ-T1-E3 application, or DG455EQ-T1-E3 equivalent, key selection criteria include its 44 V maximum supply rating, 80 ns turn-on time, 0.2 Ω on-resistance flatness, TTL/CMOS-compatible control inputs, and TSSOP-16 package compatibility with legacy DG41x series (excluding VL supply requirement).
Technical Context
The DG455EQ-T1-E3 implements four independent CMOS transmission gates with complementary control logic - each switch activates on logic low (NO function), contrasting with the DG454's NC behavior. Its architecture supports rail-to-rail analog signal handling up to ±15 V with symmetrical conduction in both directions when enabled.
Specified across -40 °C to +125 °C, it maintains stable on-resistance (3.8–8.3 Ω depending on supply) and sub-100 ns switching times under ±15 V dual-supply conditions. Internal ESD protection (2 kV HBM) and no-VL-supply design simplify system-level power architecture versus earlier DG41x generations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance | 4 Ω typical at ±15 V - ensures minimal insertion loss and signal attenuation in audio/video paths |
| On-resistance flatness | 0.2 Ω typical - preserves linearity and low THD (0.04 %) across full analog voltage swing |
| Supply voltage range | ±5 V, ±15 V, or 12 V single - enables flexible biasing in mixed-signal industrial and test systems |
| Switching speed | 80 ns turn-on / 60 ns turn-off - supports high-speed multiplexing in data acquisition and communications |
| Analog signal range | ±15 V - allows direct interfacing with op-amp outputs and sensor front-ends without level shifting |
| ESD protection | 2 kV HBM - enhances robustness during board assembly and field operation |
| Continuous current | 100 mA per channel - sufficient for driving 600 Ω audio loads or relay coil emulation |
Pinout & Package
Package: 16-pin TSSOP (JEDEC MS-012), 4.9 mm × 6.4 mm footprint, 0.65 mm pitch - compatible with automated SMT assembly and space-constrained PCB layouts.

| 5, 6, 12, 13 (S1–S4) | Source terminal | Analog source connection point; bidirectional conduction path when switch is ON |
| 7, 8, 11, 10 (D1–D4) | Drain terminal | Analog drain connection point; interchangeable with source for AC-coupled signals |
| 9 (GND) | Ground reference | Logic ground return; must be tied to system digital ground |
| 14 (V−) | Negative supply rail | Bias for negative analog swing; supports ±15 V operation |
| 15 (V+) | Positive supply rail | Bias for positive analog swing; max 44 V differential with V− |
| 16 (N.C.) | No connect | Internally unconnected; must remain floating or grounded per layout best practice |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DG455EY-T1-E3 | Same electrical specs; SOIC-16 package (6.4 mm × 10.0 mm) vs. TSSOP-16 (4.9 mm × 6.4 mm) | Preferred where board space permits larger footprint and hand-soldering or legacy reflow profiles apply | Select for compatibility with existing SOIC footprints or higher thermal dissipation needs (600 mW vs. 450 mW) |
| DG412DJ | Requires VL supply (2.7–5.5 V); 35 Ω on-resistance; lower voltage rating (±20 V) | Legacy drop-in for older designs using VL bias; unsuitable for ±15 V rail-to-rail or high-speed video | Choose only when maintaining backward compatibility with DG41x-based schematics and accepting performance trade-offs |
Compared with DG455EQ-T1-E3, DG455EY-T1-E3 offers identical functionality in a larger SOIC package with better thermal performance, while DG412DJ requires an extra supply rail and delivers significantly higher on-resistance - making DG455EQ-T1-E3 optimal for new designs demanding compact size, high voltage, and low distortion.

FAQ
What is the maximum supply voltage rating for DG455EQ-T1-E3?
The DG455EQ-T1-E3 has an absolute maximum V+ to V− rating of 44 V. It is fully specified for operation at ±5 V, ±15 V dual supplies, and 12 V single supply. Exceeding these limits risks permanent damage, and internal clamping diodes activate if analog signals exceed V+ or V− rails - forward current must be limited to rated values per datasheet Note a.
Does DG455EQ-T1-E3 require a separate VL logic supply?
No, DG455EQ-T1-E3 does not require a VL supply. Unlike the DG41x family, it derives logic-level compatibility directly from V+ and V−, supporting TTL/CMOS inputs (0.8 V low / 2.4 V high thresholds) without additional biasing - simplifying power architecture and reducing component count in new designs.
What is the on-resistance flatness specification for DG455EQ-T1-E3 and why does it matter?
DG455EQ-T1-E3 exhibits 0.2 Ω typical on-resistance flatness over the ±10 V analog range. This tight variation ensures consistent gain and minimal harmonic distortion across the signal swing - critical for high-fidelity audio switching and precision instrumentation where THD must stay below 0.04 %.
Can DG455EQ-T1-E3 be used in single-supply 12 V systems?
Yes, DG455EQ-T1-E3 is fully characterized for 12 V single-supply operation (V+ = 12 V, V− = 0 V), delivering 5.5 Ω typical on-resistance and 132 ns turn-on time. Its analog signal range extends from 0 V to 12 V, supporting DC-coupled sensor interfaces and industrial control I/O without level-shifting circuitry.
Is DG455EQ-T1-E3 pin-compatible with DG412 devices?
DG455EQ-T1-E3 is pin-compatible with DG412 in TSSOP-16 and SOIC-16 packages, but removes the VL supply pin requirement. While pinout matches, designers must omit the VL connection and verify timing/performance meets system requirements - especially regarding on-resistance (4 Ω vs. 35 Ω) and voltage ratings (±15 V vs. ±20 V).
