Vishay Siliconix DG411HSDY

Overview

DG411HSDY from Vishay Siliconix is a precision monolithic quad SPST CMOS analog switch designed for high-speed, low-error switching of bipolar ±15 V analog signals in battery-powered and portable instrumentation. It delivers 25 Ω on-resistance, 68 ns turn-on time, and 0.35 µW quiescent power dissipation across -40 °C to +85 °C, enabling use in precision data acquisition and automatic test equipment.

For engineers reviewing the DG411HSDY datasheet, DG411HSDY pinout, DG411HSDY application, or DG411HSDY equivalent, key selection considerations include its SOIC-16 package, break-before-make logic (active-low control), ±15 V analog signal range, and compatibility with TTL/CMOS logic levels at VL = 5 V.

Technical Context

The DG411HSDY implements four independent single-pole single-throw (SPST) switches built on a high-voltage silicon gate process, supporting dual-supply operation up to ±15 V and unipolar operation up to 12 V. Each channel exhibits bidirectional conduction when on and blocks voltages up to supply rails when off.

It uses active-low digital control logic (INx = 0 → ON; INx = 1 → OFF), features integrated epitaxial latchup protection, and maintains ultra-low charge injection (22 pC) and leakage (±0.1 nA typical off-leakage) - critical for precision sampling and multiplexing applications requiring minimal signal disturbance.

FAQ

What is the maximum analog signal voltage the DG411HSDY can switch?

The DG411HSDY supports an analog signal range of ±15 V when operated with dual supplies (V+ = +15 V, V− = −15 V). Its absolute maximum rating allows V+ to V− up to 44 V, but the usable linear analog swing remains bounded by the supply rails. Exceeding ±15 V risks clamping by internal protection diodes and increased leakage, so ±15 V is the guaranteed linear operating limit specified in the datasheet for the DG411HSDY.

Does the DG411HSDY require separate logic and analog grounds?

The DG411HSDY does not mandate separate logic and analog grounds, but best practice recommends separating GND paths for VL (logic supply) and analog circuitry to minimize digital noise coupling into sensitive analog nodes. The device shares a single GND pin, so system-level partitioning - including star grounding and proper decoupling of VL and V± - is essential to achieve specified leakage (<0.25 nA) and crosstalk (−88 dB) performance in the DG411HSDY.

Can the DG411HSDY operate from a single 5 V supply?

No - the DG411HSDY cannot operate from a single 5 V supply. Its minimum total supply voltage (V+ to V−) is 10 V for functional switching, and the datasheet specifies unipolar operation only up to V+ = 12 V with V− = 0 V. At 5 V, R_DS(on) degrades significantly (>100 Ω), t_ON exceeds 180 ns, and analog range collapses to 0–12 V (not 0–5 V). For true 5 V single-supply analog switching, consider alternatives like the DG417 or ADG1419, not the DG411HSDY.

What is the meaning of the "-T1-E3" suffix in DG411HSDY-T1-E3?

The "-T1" suffix indicates tape-and-reel packaging (1,000 units per reel), and "-E3" denotes lead-free, RoHS-compliant terminations per JEDEC J-STD-609. This matches the narrow SOIC package (MS-012) and confirms compliance with environmental regulations. The base part DG411HSDY refers specifically to the 16-pin narrow SOIC variant, and the full ordering code DG411HSDY-T1-E3 identifies the exact factory-packaged, RoHS-compliant version stocked and distributed by Aetrix Electronics.

How does the DG411HSDY differ from the DG412HSDY and DG413HSDY?

The DG411HSDY uses active-low control logic (IN = 0 → ON), whereas the DG412HSDY uses active-high logic (IN = 1 → ON); both are quad SPST. The DG413HSDY integrates two normally-open and two normally-closed switches in one package and supports break-before-make timing (t_D = 20 ns). All three share identical electrical specs (R_DS(on), t_ON, leakage) and package, but differ strictly in control logic polarity and switch configuration - making them functionally non-interchangeable without board-level redesign. The DG411HSDY is not a drop-in replacement for either.
