Product details
Overview
DG451EY-T1-E3 from Vishay Siliconix is a high-voltage quad SPST analog switch with 4 Ω typical on-resistance, ±15 V analog signal range, and 44 V supply maximum rating. It operates across dual supplies (±5 V, ±15 V) or single 12 V, supports 100 mA continuous current per channel, and delivers fast switching (80 ns turn-on, 60 ns turn-off) for precision audio/video routing.
For engineers reviewing the DG451EY-T1-E3 datasheet, DG451EY-T1-E3 pinout, DG451EY-T1-E3 application, or DG451EY-T1-E3 equivalent, key selection criteria include on-resistance flatness (0.2 Ω typical), ultra-low power dissipation (18 µW), TTL/CMOS compatibility, and pin compatibility with legacy DG411-series switches in SOIC-16 packaging.
Technical Context
The DG451EY-T1-E3 implements four independent normally closed (NC) SPST analog switches with symmetrical bidirectional conduction and rail-to-rail analog signal handling up to ±15 V. Its CMOS architecture ensures low charge injection (22 pC typical) and high off-isolation (–60 dB at 1 MHz).
It features dedicated logic supply (VL = 5 V) decoupled from analog rails (V+, V–), enabling clean digital control under mixed-supply conditions. Input thresholds (0.8 V low / 2.4 V high) guarantee robust TTL/CMOS interfacing without level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance | 4 Ω typical - enables low-insertion-loss signal paths for precision audio and data acquisition |
| Analog signal range | ±15 V - supports full-rail operation with dual ±15 V supplies, ideal for industrial sensor interfaces |
| Supply voltage max | 44 V (V+ to V−) - provides margin for transient overvoltage protection in automotive and avionics systems |
| Switching speed | 80 ns tON, 60 ns tOFF - meets video bandwidth requirements up to ~4 MHz (–3 dB) |
| Power dissipation | 18 µW typical - eliminates thermal concerns in dense PCB layouts and battery-powered instruments |
| ESD rating | 2 kV HBM - enhances robustness during board assembly and field handling without external protection |
| Leakage current | ±0.1 nA typical (off-state) - preserves signal integrity in high-impedance sample-and-hold and precision DAC output stages |
Pinout & Package
Package: 16-pin narrow SOIC (SOIC-16, JEDEC MS-012), body width 3.9 mm, lead pitch 1.27 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 10, 14 (IN1–IN4) | Digital control input | Active-high logic inputs controlling NC switches; 0.8 V/2.4 V TTL/CMOS thresholds ensure direct microcontroller interface |
| 2, 4, 11, 13 (S1–S4) | Source terminal | Normally connected to analog signal source; bidirectional conduction allows flexible signal routing direction |
| 3, 6, 12, 15 (D1–D4) | Drain terminal | Normally connected to load or next stage; equal on-resistance in either direction maintains signal symmetry |
| 7 (V−) | Negative analog supply | Bias reference for negative rail operation; must be ≤25 V below GND per absolute max rating |
| 8 (V+) | Positive analog supply | Supports up to +44 V relative to V−; sets upper limit of analog signal swing |
| 9 (GND) | Analog ground reference | Common return for analog signals; separate from VL supply to minimize digital noise coupling |
| 16 (VL) | Logic supply | 5 V dedicated rail for digital inputs only; isolates logic switching noise from analog path |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog switching | Handles signals from V− to V+ without clipping - critical for ±10 V instrumentation amplifier outputs |
| On-resistance flatness | 0.2 Ω typical - minimizes THD (0.04 %) in audio paths by maintaining linear gain vs. signal voltage |
| Charge injection | 22 pC typical - reduces droop error in sample-and-hold circuits with 1 nF hold capacitors |
| Off-isolation | –60 dB at 1 MHz - suppresses crosstalk between adjacent channels in multi-channel ATE systems |
| Pin compatibility | Direct replacement for DG411EY-T1-E3 - enables drop-in upgrade to lower RON and improved flatness |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DG411EY-T1-E3 | Higher on-resistance (35 Ω typical), slower switching (150 ns tON), same SOIC-16 pinout | Lower bandwidth and higher distortion limit use in audio/video; suitable only for DC/low-frequency multiplexing | Select DG451EY-T1-E3 when upgrading legacy designs requiring lower RON, faster speed, or improved THD. |
| MAX4511ESE+ | 10 Ω on-resistance, ±20 V signal range, 16-pin SOIC but different pin assignment (non-pin-compatible) | Requires PCB redesign; better for ±20 V systems but lacks DG451's 0.2 Ω flatness and 22 pC charge injection | Choose MAX4511ESE+ only if ±20 V range is mandatory and layout revision is acceptable. |
Compared with DG411EY-T1-E3 and MAX4511ESE+, DG451EY-T1-E3 uniquely combines 4 Ω RON, 0.2 Ω flatness, and pin compatibility-enabling performance upgrades without layout changes or signal-path compromises.

FAQ
What is the maximum analog signal voltage range supported by DG451EY-T1-E3?
DG451EY-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. This rail-to-rail capability ensures full utilization of the supply rails without signal clipping, making it suitable for high-dynamic-range instrumentation and industrial sensor interfaces.
Is DG451EY-T1-E3 pin-compatible with older Vishay analog switches?
Yes, DG451EY-T1-E3 is pin-compatible with DG411EY-T1-E3, DG412EY-T1-E3, and DG413EY-T1-E3 in the same SOIC-16 package. This allows direct replacement in existing designs to improve on-resistance, switching speed, and THD without PCB modifications.
What is the typical on-resistance flatness of DG451EY-T1-E3 and why does it matter?
DG451EY-T1-E3 has a typical on-resistance flatness of 0.2 Ω across its analog signal range. This tight variation ensures consistent gain and minimal harmonic distortion-critical for high-fidelity audio switching and precision measurement where signal linearity directly impacts accuracy.
Can DG451EY-T1-E3 operate from a single 12 V supply?
Yes, DG451EY-T1-E3 is fully specified for unipolar operation with V+ = 12 V and V− = 0 V. In this configuration, it supports analog signals from 0 V to +12 V, delivers 5.5 Ω typical on-resistance, and maintains 132 ns turn-on time-ideal for industrial PLC I/O modules and portable test equipment.
What logic voltage levels are compatible with DG451EY-T1-E3 digital inputs?
DG451EY-T1-E3 digital inputs accept standard TTL/CMOS logic levels: 0.8 V maximum for logic low and 2.4 V minimum for logic high, referenced to VL = 5 V. This allows direct interfacing with 3.3 V and 5 V microcontrollers, FPGAs, and logic families without level shifters.
