Vishay Siliconix DG411HSDJ

Overview

DG411HSDJ 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 portable and battery-powered systems. It features 25 Ω on-resistance, 68 ns turn-on time, 0.35 µW power dissipation, and operates from ±15 V dual supplies or 12 V single supply.

For engineers reviewing the DG411HSDJ datasheet, DG411HSDJ pinout, DG411HSDJ application, or DG411HSDJ equivalent, key selection criteria include break-before-make timing, channel leakage (±0.1 nA), off-isolation (–91 dB at 1 MHz), charge injection (22 pC), and compatibility with TTL/CMOS logic levels across –40 °C to +85 °C.

Technical Context

The DG411HSDJ implements four independent normally open (NO) SPST switches fabricated on Vishay's high-voltage silicon gate process with epitaxial latchup protection. Each channel conducts bidirectionally with matched on-resistance and supports analog signals up to ±15 V when powered by ±15 V supplies.

Control logic is active-low: logic 0 enables conduction (ON), logic 1 disables (OFF). The device integrates level-shifting circuitry enabling 5 V logic control (VL = 5 V) while switching ±15 V analog rails, and includes internal clamping diodes limiting signal excursions beyond V+ or V–.

FAQ

What is the maximum analog signal voltage supported by DG411HSDJ?

DG411HSDJ supports analog signals from –15 V to +15 V when operated with ±15 V supplies. Its absolute maximum rating allows V+ to V– up to 44 V, but the guaranteed linear analog range remains ±15 V per the datasheet specification. Exceeding ±15 V risks increased on-resistance variation and reduced linearity, so DG411HSDJ must be used within this range for precision applications.

Does DG411HSDJ require external pull-up resistors on its INx pins?

No, DG411HSDJ does not require external pull-up resistors on its IN1–IN4 pins. Its digital inputs are TTL/CMOS compatible with defined thresholds (0.8 V low, 2.4 V high) and exhibit ultra-low input current (±0.5 µA max), allowing direct connection to microcontroller GPIOs. DG411HSDJ's internal structure ensures reliable logic-level recognition without external biasing.

Can DG411HSDJ operate from a single 12 V supply?

Yes, DG411HSDJ supports unipolar operation with V+ = 12 V and V– = 0 V, delivering a 0 V to 12 V analog signal range. In this configuration, R_DS(on) increases to 49 Ω typical and t_ON rises to 95 ns, but all core functionality-including break-before-make timing and 5 V logic compatibility via VL-remains fully operational for DG411HSDJ.

What is the purpose of the VL pin on DG411HSDJ?

The VL pin on DG411HSDJ provides a dedicated 5 V logic supply reference that decouples digital control circuitry from analog supplies. This ensures stable, noise-immune switching thresholds regardless of V+ or V– fluctuations. For DG411HSDJ, VL must be connected to a clean 5 V source; it is not internally regulated and directly sets the input logic voltage levels.

How does DG411HSDJ achieve latchup immunity?

DG411HSDJ achieves latchup immunity through Vishay Siliconix's proprietary high-voltage silicon gate process featuring an epitaxial layer that electrically isolates the CMOS switching elements. This structure prevents parasitic SCR formation under transient overvoltage or ESD events, allowing DG411HSDJ to withstand stresses beyond absolute maximum ratings without destructive latchup-a critical requirement for field-deployed instrumentation.
