Product details
Overview
DG456EQ-T1-E3 from Vishay Siliconix is a high-voltage quad SPST analog switch IC with two normally closed (NC) and two normally open (NO) channels, 4 Ω typical on-resistance, ±15 V analog signal range, and 44 V supply rating-designed for precision audio/video routing in industrial test equipment and relay-replacement systems.
For engineers reviewing the DG456EQ-T1-E3 datasheet, DG456EQ-T1-E3 pinout, DG456EQ-T1-E3 application, or DG456EQ-T1-E3 equivalent, key selection criteria include break-before-make timing (70 ns at +12 V), charge injection (1 pC), on-resistance flatness (0.94 Ω), and TSSOP-16 compatibility with DG411/DG412/DG413 footprints (no VL supply required).
Technical Context
The DG456EQ-T1-E3 implements a CMOS-based quad SPST architecture with dual independent logic control inputs per pair: IN1/IN2 drive SW1/SW4 (NC) and SW2/SW3 (NO) respectively, enabling simultaneous but opposite switching states. Its rail-to-rail analog conduction supports bidirectional signal flow across ±15 V, ±5 V, or +12 V supplies without level-shifting.
Break-before-make operation is intrinsic to the DG456 variant (not DG454/DG455), with tD = 70 ns at +12 V supply, ensuring no transient shorting during channel transitions. All digital inputs meet TTL/CMOS thresholds (0.8 V low, 2.4 V high) and are ESD-protected to 2 kV HBM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (typ.) | 5.5 Ω at +12 V supply - enables low insertion loss in audio paths and minimal gain error in precision data acquisition |
| On-resistance flatness | 0.94 Ω over 0–10 V range - ensures consistent THD (<0.04%) and minimal harmonic distortion in wideband signals |
| Analog signal range | ±15 V dual supply or 0–12 V single supply - supports full-rail signal handling without clipping in instrumentation front-ends |
| Switching speed (tON/tOFF) | 132 ns / 61 ns at +12 V - suitable for video switching up to ~3 MHz bandwidth with <1% settling error |
| Charge injection | 1 pC at +12 V - minimizes voltage glitch in sample-and-hold circuits and ADC input multiplexing |
| Off-isolation (OIRR) | -60 dB at 1 MHz - provides strong channel separation in multi-channel audio or sensor multiplexing |
| Continuous current rating | 100 mA per channel - supports direct driving of moderate-load transducers or relays without external buffering |
Pinout & Package
TSSOP-16 package (JEDEC MS-012, 5.0 mm × 4.4 mm × 1.2 mm), lead-free, RoHS-compliant, rated for -40 °C to +125 °C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN1) | Digital control input for SW1 & SW4 | Active-high logic drives NC switches ON; inverted relative to IN2 for complementary control |
| 2 (IN2) | Digital control input for SW2 & SW3 | Active-high logic drives NO switches ON; enables break-before-make sequencing with IN1 |
| 3 (D1) | Drain terminal of SW1 | High-voltage analog node; connects to load or downstream circuit; bidirectional conduction when ON |
| 4 (D2) | Drain terminal of SW2 | Independent analog path; isolated from D1 when both switches are OFF (OIRR = -60 dB) |
| 5 (S1) | Source terminal of SW1 | Connects to common analog source (e.g., DAC output); must remain within V− to V+ rails |
| 6 (S2) | Source terminal of SW2 | Separate source node; allows differential or independent signal routing per channel pair |
| 7 (V−) | Negative supply rail | Required for dual-supply operation; clamps analog inputs exceeding V− via internal diodes |
| 8 (V+) | Positive supply rail | Supports up to +44 V max; defines upper analog rail limit and powers internal logic |
| 9 (GND) | Digital ground reference | Logic return path; separate from analog ground in mixed-signal layouts to minimize noise coupling |
| 10 (N.C.) | No-connect terminal | Internally unconnected; must be left floating or tied to GND per PCB layout best practices |
| 11 (S4) | Source terminal of SW4 | Second NC source; paired with D1 for redundant or mirrored signal paths |
| 12 (S3) | Source terminal of SW3 | Second NO source; complements S2 for dual-channel switching in automated test fixtures |
| 13 (D4) | Drain terminal of SW4 | Matches D1 functionality; enables identical routing for dual NC channels |
| 14 (D3) | Drain terminal of SW3 | Matches D2 functionality; supports parallel or interleaved switching in high-density mux designs |
| 15 (IN4) | Unused (no internal connection) | Not bonded; electrically isolated; may be omitted from schematic symbol |
| 16 (IN3) | Unused (no internal connection) | Not bonded; electrically isolated; no PCB trace required |
Key Features
| Feature | Design Value |
|---|---|

| Break-before-make timing | 70 ns delay between SW1/SW4 turn-OFF and SW2/SW3 turn-ON at +12 V-prevents momentary shorts in relay-replacement topologies |
| Rail-to-rail analog conduction | Signals swing from V− to V+ without degradation-enables direct interface with op-amps, ADCs, and DACs operating at supply rails |
| TTL/CMOS-compatible inputs | 0.8 V/2.4 V thresholds ensure reliable logic recognition across 3.3 V and 5 V microcontrollers without level shifters |
| Low charge injection (1 pC) | Reduces hold-step error in sample-and-hold circuits to <1 mV for 1 nF capacitors-critical for 12-bit+ data acquisition |
| ESD protection (2 kV HBM) | Withstands handling and board-level ESD events without latch-up or parametric shift-improves manufacturing yield |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4566ESE+ | Single-supply only (2.7–12 V), 12 Ω RON, no break-before-make, SOIC-16 | Limited to low-voltage systems; unsuitable for ±15 V signal routing or relay replacement | Select when cost-sensitive, single-rail designs dominate and high-voltage capability is unnecessary. |
| ADG1414BRUZ | Quad SPST, 1.3 Ω RON, ±15 V rating, but requires VL supply and has no break-before-make | Superior on-resistance but lacks DG456EQ-T1-E3's integrated sequencing-requires external logic for safe channel transition | Choose for ultra-low RON in precision instrumentation where external control logic is already present. |
Compared with MAX4566ESE+ and ADG1414BRUZ, DG456EQ-T1-E3 uniquely combines ±15 V operation, intrinsic break-before-make timing, and no-VL simplicity-making it optimal for robust, self-contained high-voltage analog switching without added control complexity.

FAQ
What is the maximum supply voltage rating for DG456EQ-T1-E3?
The DG456EQ-T1-E3 has an absolute maximum V+ to V− rating of 44 V. It is fully specified for dual supplies of ±5 V, ±15 V, and single supply of +12 V. Operation beyond these conditions risks permanent damage, and signals exceeding the supply rails are clamped by internal diodes-forward current must be limited to rated values.
Does DG456EQ-T1-E3 require a separate VL logic supply?
No, DG456EQ-T1-E3 does not require a VL supply. Unlike legacy parts such as DG411/DG412/DG413, it derives all logic-level translation internally from V+ and V−, simplifying power design and reducing bill-of-materials count. This is explicitly confirmed in the datasheet's Features section and ordering table notes.
How does the break-before-make function work in DG456EQ-T1-E3?
The DG456EQ-T1-E3 implements intrinsic break-before-make timing between its NC (SW1/SW4) and NO (SW2/SW3) switch pairs. When IN1 and IN2 are driven with complementary logic, tD = 70 ns at +12 V ensures SW1/SW4 turn OFF before SW2/SW3 turn ON-preventing momentary shorting. This behavior is unique to the DG456 variant and is verified in the Truth Table and Dynamic Characteristics tables.
What is the typical on-resistance flatness of DG456EQ-T1-E3 and why does it matter?
The DG456EQ-T1-E3 has a typical on-resistance flatness of 0.94 Ω over the 0–10 V range under +12 V supply. This low variation ensures minimal signal-dependent gain error and harmonic distortion-critical for high-fidelity audio and precision measurement applications where THD must stay below 0.04%.
Is DG456EQ-T1-E3 pin-compatible with DG411/DG412/DG413?
Yes, DG456EQ-T1-E3 is pin-compatible with DG411, DG412, and DG413 in TSSOP-16 and SOIC-16 packages, as stated in the datasheet's Functional Block Diagram section. However, DG456EQ-T1-E3 omits the VL pin (pin 10 is N.C.), so PCB layouts must accommodate this difference-no VL trace is needed, and pin 10 should remain unconnected.
