Product details
Overview
DG412HSDY from Vishay Siliconix is a precision monolithic quad SPST CMOS analog switch with opposite logic control versus DG411HS, 25 Ω on-resistance, 68 ns turn-on time, ±15 V analog signal range, and 44 V supply rating - used in battery-powered precision data acquisition and automatic test equipment.
For engineers reviewing the DG412HSDY datasheet, DG412HSDY pinout, DG412HSDY application, or DG412HSDY equivalent, key selection considerations include its break-before-make timing behavior, TTL/CMOS compatibility, single-supply operation capability, and SOIC-16 package thermal performance under -40 °C to +85 °C industrial temperature range.
Technical Context
The DG412HSDY implements four independent bidirectional analog switches fabricated on Vishay's high-voltage silicon gate process with epitaxial latchup protection. Each channel supports rail-to-rail analog signals up to ±15 V and exhibits symmetrical conduction when on and full blocking when off.
Its control logic is inverted relative to DG411HS (logic 0 = ON, logic 1 = OFF), enabling complementary switching configurations in multiplexer or signal routing designs. Dynamic performance is characterized by 68 ns tON and 42 ns tOFF at ±15 V dual supply with 300 Ω load and 35 pF capacitance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V - supports full-scale precision signal switching without clipping in bipolar instrumentation front-ends |
| On-Resistance (RDS(on)) | 25 Ω typical - ensures low insertion loss and minimal gain error in precision gain-setting or filter paths |
| Turn-On Time (tON) | 68 ns - enables sub-15 MHz switching rates for high-speed multiplexed ADC sampling |
| Supply Voltage Range | ±15 V max (44 V total) - accommodates wide dynamic range systems including industrial PLC I/O modules |
| Logic Compatibility | TTL/CMOS - simplifies interface to microcontrollers, FPGAs, and legacy digital logic without level-shifting |
| Power Dissipation | 0.35 µW - allows integration into ultra-low-power portable instruments with negligible thermal impact |
| Off-Isolation (OIRR) | -91 dB at 1 MHz - suppresses crosstalk between adjacent channels in multi-channel DAQ systems |
Pinout & Package
Package: 16-pin narrow SOIC (JEDEC MS-012), 3.8 mm × 9.9 mm body, 1.27 mm pitch, RoHS-compliant lead finish (E3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 | Digital control inputs | Inverted logic: low = switch ON; compatible with 5 V TTL/CMOS drivers |
| S1–S4 | Switch source terminals | Bidirectional analog inputs; connect to signal sources or sensor outputs |
| D1–D4 | Switch drain terminals | Bidirectional analog outputs; route to ADC inputs, amplifiers, or filters |
| V+ | Positive analog supply | Accepts up to +20 V; sets upper analog rail and powers internal circuitry |
| V- | Negative analog supply | Accepts down to -20 V; defines lower analog rail and enables true bipolar operation |
| GND | Analog ground reference | Common return for V+ and V- supplies; must be low-impedance for noise immunity |
| VL | Logic supply voltage | Accepts 2.4 V to 5.5 V; decouples logic threshold from analog rails for robust noise rejection |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Prevents momentary shorting during channel transitions - critical for avoiding signal glitches in multiplexed sensor arrays |
| Ultra-low power consumption | 0.35 µW quiescent - extends battery life in handheld meters and portable medical devices |
| High-voltage silicon gate process | Enables 44 V V+–V- rating and latchup immunity - suitable for harsh industrial environments |
| Low charge injection (22 pC) | Minimizes voltage step errors at switch closure - preserves accuracy in sample-and-hold and precision DAC output stages |
| Low off-capacitance (12 pF) | Reduces capacitive coupling between inactive channels - improves isolation in high-frequency signal routing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4612ESE+ | Higher RDS(on) (45 Ω), slower tON (120 ns), same SOIC-16 package | Lower bandwidth suitability; less ideal for >5 MHz multiplexing | Select when cost sensitivity outweighs speed and on-resistance requirements |
| ADG1412BRUZ | Lower RDS(on) (1.8 Ω), higher supply rating (±20 V), TSSOP-16 package | Superior linearity but requires PCB redesign due to different footprint and thermal pad | Select for ultra-low distortion audio or precision metrology where 25 Ω is insufficient |
Compared with MAX4612ESE+ and ADG1412BRUZ, DG412HSDY delivers optimal balance of speed, on-resistance, and SOIC-16 compatibility for industrial DAQ and portable test gear - offering verified -40 °C to +85 °C operation without derating.

FAQ
What is the logic polarity of DG412HSDY compared to DG411HSDY?
The DG412HSDY uses inverted control logic: a logic low (≤0.8 V) turns the switch ON, while a logic high (≥2.4 V) turns it OFF. This is the opposite of DG411HSDY, which activates on logic high. This complementary behavior allows coordinated switching in differential or redundant signal path designs without external inverters. The DG412HSDY truth table is explicitly defined in Vishay document 72053 Rev. D.
Does DG412HSDY support single-supply operation?
Yes, DG412HSDY supports unipolar supplies - it operates with V+ = 12 V and V- = 0 V, delivering an analog signal range of 0 V to 12 V. In this configuration, RDS(on) increases to 49 Ω typical, and tON extends to 95 ns, as specified in the unipolar section of the datasheet. The VL pin remains at 5 V for logic interfacing, independent of analog rail voltages.
What is the maximum allowable analog signal voltage for DG412HSDY?
The DG412HSDY supports analog signals from V- to V+, with absolute limits of ±15 V when using dual supplies. With V+ = 15 V and V- = -15 V, the full analog range is -15 V to +15 V. Signals exceeding these rails are clamped by internal diodes; forward diode current must be limited to ≤30 mA per terminal to avoid damage, per Note (a) in the Absolute Maximum Ratings table.
How does DG412HSDY handle charge injection in sample-and-hold circuits?
DG412HSDY specifies 22 pC typical charge injection at ±15 V supplies, measured with Vg = 0 V and CL = 10 nF. This low value minimizes voltage step errors at switch closure, preserving DC accuracy in precision sample-and-hold stages. For best results, pair DG412HSDY with low-input-bias-current op-amps and use guard traces to isolate the hold capacitor node from noisy digital lines.
Is DG412HSDY RoHS compliant?
Yes, the DG412HSDY-E3 and DG412HSDY-T1-E3 variants are RoHS compliant, using lead-free terminations. The "E3" suffix denotes lead-free, halogen-free, and RoHS-compliant packaging per Vishay's standard product marking convention. Full compliance documentation, including test reports and substance declarations, is available via Vishay's quality portal under document number 72053.
