Product details
Overview
DG456EY-T1-E3 from Vishay Siliconix is a high-voltage quad SPST analog switch 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 and relay replacement in industrial test equipment.
For engineers reviewing the DG456EY-T1-E3 datasheet, DG456EY-T1-E3 pinout, DG456EY-T1-E3 application, or DG456EY-T1-E3 equivalent, key selection criteria include break-before-make timing (70 ns at +12 V), on-resistance flatness (0.25 Ω typ), charge injection (1 pC at +12 V), and dual-supply (±5 V/±15 V) or single-supply (12 V) operation compatibility.
Technical Context
The DG456EY-T1-E3 implements a CMOS-based quad SPST architecture with independent digital control inputs per channel and no VL bias requirement-enabling direct TTL/CMOS logic interfacing without auxiliary voltage rails. Its internal structure supports bidirectional analog conduction across full rail-to-rail input ranges up to ±15 V or 0–12 V.
Unlike the DG454 (all-NC) and DG455 (all-NO), the DG456 integrates mixed NC/NO topology in one package, delivering break-before-make switching behavior critical for preventing signal shorting during channel transitions-verified at 70 ns delay under +12 V unipolar conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance | 5.5 Ω typ at +12 V supply - ensures low insertion loss and minimal signal attenuation in audio/video paths |
| On-resistance flatness | 0.94 Ω typ at +12 V - maintains consistent gain and THD performance across full analog voltage swing (0–10 V) |
| Break-before-make delay | 70 ns at +12 V - prevents momentary short-circuit between channels during switching transitions |
| Charge injection | 1 pC at +12 V - minimizes voltage glitch in sample-and-hold or precision data acquisition circuits |
| Analog signal range | 0 to +12 V (unipolar) or ±15 V (bipolar) - supports rail-to-rail signal handling without clamping in active circuitry |
| Supply voltage rating | 44 V max (V+ to V−) - enables robust operation in high-voltage industrial and automotive environments |
| Switching speed | tON = 132 ns / tOFF = 61 ns at +12 V - meets video bandwidth requirements up to ~20 MHz |
Pinout & Package
Package: 16-pin narrow SOIC (JEDEC MS-012), 6.10–6.70 mm width, 10.00 mm length, 1.10–1.20 mm height, 1.27 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 (IN1–IN4) | Digital control inputs | Active-high logic inputs controlling individual switch states; compatible with 0.8 V/2.4 V TTL/CMOS thresholds |
| 5, 6, 13, 14 (S1–S4) | Source terminals | Analog current source nodes; conduct bidirectionally when corresponding switch is ON |
| 7, 8, 11, 12 (D1–D4) | Drain terminals | Analog current sink nodes; mirror S-terminal behavior with identical conduction characteristics |
| 9 (GND) | Ground reference | Logic ground return; must be connected to system ground for proper digital interface operation |
| 10 (N.C.) | No-connect | Internally unused pin; must remain floating or grounded per PCB layout best practices |
| 15 (V−) | Negative supply rail | Bipolar operation: connects to −15 V or −5 V; unipolar operation: ties to GND |
| 16 (V+) | Positive supply rail | Supplies internal switch array; accepts +12 V (unipolar) or +15 V/+5 V (bipolar) |
Key Features
| Feature | Design Value |
|---|---|
| Mixed NC/NO configuration | Two normally closed and two normally open switches enable flexible signal path redundancy and fail-safe routing |
| No VL supply required | Eliminates need for separate logic-level bias rail-reduces BOM count and simplifies power domain partitioning |
| Break-before-make timing | Guaranteed 70 ns delay at +12 V prevents cross-conduction during channel switching in multiplexer applications |
| Rail-to-rail analog operation | Supports input signals extending to V+ and V− rails-critical for high-fidelity audio and wide-dynamic-range sensor interfaces |
| Low charge injection | 1 pC at +12 V minimizes sampling error in precision ADC front-ends and sample-and-hold circuits |

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 on-resistance; no break-before-make guarantee | Limited to low-voltage portable systems; unsuitable for ±15 V bipolar operation or high-precision THD-sensitive designs | Select when cost and footprint are prioritized over rail-to-rail analog range and THD performance |
| ADG1414BRUZ | Higher on-resistance (1.3 Ω min at ±15 V); 4-channel SPST with all-NO configuration; requires VL | Superior bandwidth (170 MHz) but lacks NC/NO mix; VL dependency increases power design complexity | Prefer for high-frequency RF/data-acquisition where low RON and fast switching outweigh NC/NO flexibility needs |
Compared with MAX4566ESE+ and ADG1414BRUZ, the DG456EY-T1-E3 uniquely combines mixed NC/NO topology, no-VL operation, and guaranteed break-before-make timing-making it optimal for fault-tolerant industrial multiplexing where signal path integrity and supply simplicity are co-prioritized.

FAQ
What is the maximum analog signal voltage range supported by DG456EY-T1-E3?
The DG456EY-T1-E3 supports an analog signal range of ±15 V with dual supplies (±15 V or ±5 V) and 0–12 V with single supply (+12 V). Signals exceeding V+ or V− are clamped by internal diodes; forward diode current must be limited to rated maximums per datasheet Note a. This capability makes DG456EY-T1-E3 suitable for rail-to-rail signal handling in precision instrumentation and industrial control interfaces.
Does DG456EY-T1-E3 require a separate VL logic supply?
No, DG456EY-T1-E3 does not require a VL supply. It operates directly from standard TTL/CMOS logic levels (0.8 V low, 2.4 V high) referenced to its main power rails (V+, V−, GND). This eliminates the need for an auxiliary bias rail, simplifying PCB layout and reducing BOM count compared to legacy analog switches like the DG411/DG412 family. The absence of VL is explicitly confirmed in the Vishay DG454/DG455/DG456 datasheet Section "Features".
What is the break-before-make timing specification for DG456EY-T1-E3?
The DG456EY-T1-E3 guarantees a break-before-make time delay of 70 ns under +12 V unipolar supply conditions (V+ = +12 V, V− = GND), as specified in the "Dynamic Characteristics" table on page 4 of the Vishay datasheet. This parameter applies only to the DG456 variant due to its mixed NC/NO architecture and ensures no overlap between switch closure and opening-critical for preventing signal shorting in multiplexer and relay-replacement applications.
Can DG456EY-T1-E3 operate with ±5 V dual supplies?
Yes, DG456EY-T1-E3 is fully specified for ±5 V dual-supply operation. At ±5 V, it delivers 3.8 Ω typical on-resistance, 0.13 Ω on-resistance match, and 170 ns turn-on time (tON). These parameters are validated across −40 °C to +125 °C and published in the "Specifications for Dual Supplies" tables on pages 3–4 of the Vishay datasheet. This makes DG456EY-T1-E3 compatible with legacy ±5 V logic and analog systems.
What package type is used for DG456EY-T1-E3?
DG456EY-T1-E3 uses a 16-pin narrow SOIC package (JEDEC MS-012), with dimensions 10.00 mm × 6.40 mm × 1.15 mm and 1.27 mm lead pitch. This package is distinct from the TSSOP variant (DG456EQ-T1-E3) and features higher power dissipation (600 mW vs. 450 mW) and lower thermal resistance (125 °C/W vs. 178 °C/W), making it preferred for thermally constrained industrial applications.
