Product details
Overview
DG412HSDY-T1 from Vishay Siliconix is a precision monolithic quad SPST CMOS analog switch optimized for high-speed, low-error switching of bipolar analog signals in battery-powered and portable instrumentation. It features 25 Ω on-resistance, 68 ns turn-on time, ±15 V analog signal range, and operates from dual ±15 V supplies - enabling use in precision data acquisition front-ends and automatic test equipment.
For engineers reviewing the DG412HSDY-T1 datasheet, DG412HSDY-T1 pinout, DG412HSDY-T1 application, or DG412HSDY-T1 equivalent, key selection criteria include break-before-make timing behavior, ultra-low 0.35 µW power dissipation, TTL/CMOS logic compatibility, and guaranteed 44 V supply rating across -40 °C to +85 °C.
Technical Context
The DG412HSDY-T1 implements four independent single-pole single-throw (SPST) switches with complementary control logic versus DG411HS - each channel conducts bidirectionally when enabled and blocks signals up to supply rails when off. Its high-voltage silicon gate process enables latchup immunity via epitaxial isolation and supports rail-to-rail analog operation.
Switching performance is defined by 68 ns tON, 42 ns tOFF, and <22 pC charge injection - critical for minimizing settling error in sampling circuits. The device accepts logic-level inputs at VL = 5 V while operating from ±15 V analog supplies, decoupling digital interface voltage from analog signal integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V - supports full-scale bipolar signal routing without clipping in precision measurement systems |
| On-Resistance (RDS(on)) | 25 Ω typical - ensures minimal gain error and channel-to-channel mismatch in multiplexed sensor interfaces |
| Turn-On Time (tON) | 68 ns - enables sub-15 MHz sample rates in high-speed data acquisition with predictable timing margins |
| Supply Voltage Max | 44 V (V+ to V−) - provides robust headroom for transient suppression and overvoltage tolerance |
| Power Dissipation | 0.35 µW - allows integration into always-on, low-power monitoring nodes without thermal derating |
| Logic Compatibility | TTL/CMOS - simplifies direct interfacing with microcontrollers and FPGAs without level-shifting circuitry |
| Charge Injection | 22 pC - limits voltage glitch amplitude on sampled-hold capacitors, reducing post-switching settling time |
Pinout & Package
Package: 16-pin narrow SOIC (JEDEC MS-012), 3.9 mm width, 1.27 mm pitch, RoHS-compliant lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 | Digital control inputs | Active-high logic; DG412HS uses inverted truth table vs DG411HS - '1' disables, '0' enables switch |
| S1–S4 | Source terminals | Analog inputs/outputs; bidirectional conduction path when corresponding switch is ON |
| D1–D4 | Drain terminals | Analog inputs/outputs; electrically identical to Sx pins; no intrinsic directionality |
| V+ | Positive analog supply | Accepts up to +22 V relative to GND; sets upper analog signal limit |
| V− | Negative analog supply | Accepts down to -22 V relative to GND; sets lower analog signal limit |
| GND | Analog ground reference | Return path for analog signals; separate from digital logic ground (VL) to minimize noise coupling |
| VL | Logic supply voltage | 5 V reference for digital inputs; isolates logic threshold from analog supply variations |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional analog conduction | Enables flexible signal routing in both directions without polarity constraints - ideal for differential sensor interfaces |
| Break-before-make switching | Prevents momentary shorting between channels during state transitions - essential for safe multiplexer sequencing |
| Latchup-immune process | Epitaxial isolation eliminates risk of destructive latchup under overvoltage or ESD stress - improves system reliability |
| Ultra-low leakage | ±0.25 nA max off-state leakage at ±15.5 V - preserves accuracy in high-impedance sensor and integrator circuits |
| Rail-to-rail analog capability | Supports input signals extending to V+ and V− rails - maximizes dynamic range in ±15 V systems |

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 ±15 V range and SOIC-16 package | Less suitable for >10 MHz sampling; acceptable where power is less constrained | Choose MAX4612ESE+ only if legacy design reuse or availability drives selection - not for new high-speed designs |
| ADG1412BRUZ | Lower RDS(on) (1.8 Ω), higher supply rating (±20 V), but larger 16-lead TSSOP package and higher cost | Better for low-offset, high-current applications; requires PCB layout revision due to different footprint | Select ADG1412BRUZ when <2 Ω on-resistance is mandatory and board space permits TSSOP; otherwise DG412HSDY-T1 offers optimal balance |
Compared with MAX4612ESE+ and ADG1412BRUZ, DG412HSDY-T1 delivers superior speed-to-power ratio and proven latchup immunity in industrial environments, making it the preferred choice for portable precision instruments requiring long-term reliability and stable parametric performance.

FAQ
What is the logic polarity of DG412HSDY-T1 compared to DG411HSDY-T1?
The DG412HSDY-T1 uses inverted control logic versus DG411HSDY-T1: a logic HIGH ('1') turns the switch OFF, and a logic LOW ('0') turns it ON. This complementary relationship is explicitly defined in the Truth Table of the DG411HS/DG412HS datasheet (Document 72053, Rev. D). Designers must verify control signal alignment in firmware or logic design to prevent unintended channel states in the DG412HSDY-T1.
Does DG412HSDY-T1 support single-supply operation?
Yes, DG412HSDY-T1 supports unipolar operation 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), tON extends to 95 ns, and leakage remains within specification. The device retains TTL/CMOS compatibility at VL = 5 V, enabling seamless integration into mixed-signal systems with shared 5 V logic rails.
What is the maximum allowable analog input voltage beyond the supply rails for DG412HSDY-T1?
Signals applied to Sx or Dx pins exceeding V+ or V− are clamped by internal protection diodes, as noted in datasheet footnote (a). Forward diode current must be limited to ≤30 mA continuous or ≤100 mA pulsed (1 ms, 10% duty cycle) to avoid damage. For sustained overvoltage conditions, external series resistors or TVS diodes are recommended to keep clamp current within safe limits per Absolute Maximum Ratings.
How does DG412HSDY-T1 achieve latchup immunity?
DG412HSDY-T1 achieves latchup immunity through Vishay Siliconix's proprietary high-voltage silicon gate process, which incorporates an epitaxial layer that electrically isolates the CMOS structure. This design prevents parasitic SCR formation under high dv/dt or overvoltage stress - a critical reliability feature confirmed in qualification testing and referenced in the device description (Document 72053, page 1). No external latchup mitigation is required in compliant layouts.
Is DG412HSDY-T1 pin-compatible with other members of the DG41xHS family in SOIC-16 packages?
Yes, DG412HSDY-T1 is pin-compatible with DG411HSDY-T1 and DG413HSDY-T1 in the 16-pin narrow SOIC package (MS-012). All three share identical pin assignments for V+, V−, GND, VL, IN1–IN4, S1–S4, and D1–D4. Functional differences (e.g., logic polarity, NO/NC configuration) are internal and do not affect physical layout - allowing drop-in replacement where signal routing and control logic are adapted accordingly.
