Product details
Overview
DG412DYZ-T from Renesas Electronics is a monolithic quad SPST CMOS analog switch with TTL/CMOS-compatible digital inputs, 35Ω max ON-resistance, 175ns max tON, and ±20V dual-supply or +5V to +44V single-supply operation. It serves as a drop-in replacement for DG212 in precision signal routing applications such as data acquisition front-ends and sample-and-hold circuits.
For engineers reviewing the DG412DYZ-T datasheet, DG412DYZ-T pinout, DG412DYZ-T application, or DG412DYZ-T equivalent, key selection criteria include its negative-logic control architecture (logic "0" = ON), low 5pC typical charge injection, bilateral signal handling up to ±15V analog range, and SOIC-16 Pb-free RoHS-compliant packaging suitable for automated SMT assembly.
Technical Context
The DG412DYZ-T implements four independent SPST switches using a high-voltage silicon-gate CMOS process with epitaxial isolation to prevent latch-up. Its negative logic control (INx = 0V → ON) distinguishes it from the DG411 series and enables direct interface with open-collector or active-low enable systems.
Each switch supports bidirectional analog signals with matched ON-resistance flatness across ±15V input range and exhibits <0.4nA typical channel ON leakage at 25°C. The VL pin provides dedicated logic reference decoupling, isolating digital switching noise from analog paths.
Key Specifications

|---|---|
| ON-Resistance (Max) | 35Ω - Ensures minimal signal attenuation and gain error in precision instrumentation paths |
| Turn-On Time (Max) | 175ns - Supports multiplexing of signals up to ~2MHz without significant settling delay |
| Charge Injection (Typ) | 5pC - Reduces voltage step errors in sample-and-hold and ADC driver stages |

| Supply Voltage Range | ±5V to ±20V or +5V to +44V - Compatible with industrial sensor interfaces and legacy ±15V systems |
| Logic Compatibility | TTL/CMOS - Interfaces directly with microcontrollers, FPGAs, and logic families without level-shifting |
| OFF Isolation (Typ) | 68dB at 1MHz - Suppresses crosstalk between adjacent channels in multi-channel DAQ systems |
Pinout & Package
Package: 16-lead SOIC (150 mil), RoHS-compliant Pb-free with matte tin terminations, JEDEC MS-012-AC compliant, body dimensions 9.80 × 3.80 × 1.75 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 (IN1–IN4) | Digital Control Input | Negative logic: 0.8V max = switch ON; requires external pull-up or active-low driver |
| 2, 15, 10, 7 (D1–D4) | Drain (Output) | Bidirectional terminal; connects to load or downstream circuitry; no polarity constraint |
| 3, 14, 11, 6 (S1–S4) | Source (Input) | Bidirectional terminal; connects to signal source; matched impedance with drain pins |
| 4 (V−) | Negative Supply Rail | Reference for negative analog swing; must be decoupled locally for noise immunity |
| 5 (GND) | Logic Ground | Return path for digital inputs only; separate from analog ground in mixed-signal layouts |
| 12 (VL) | Logic Reference Voltage | Accepts 0.3V below GND to V+ +0.3V; typically tied to 5V for TTL compatibility |
| 13 (V+) | Positive Supply Rail | Substrate connection; sets upper analog rail limit and powers internal bias networks |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4612ESE+ | Quad SPST, positive logic (IN=1→ON), 35Ω max rDS(ON), 125ns max tON, SOIC-16 | Requires logic inversion for DG412DYZ-T drop-in use; slightly faster switching but higher charge injection (15pC) | Select when system uses active-high control and timing margin is critical over charge error |
| ADG1412BRUZ | Quad SPST, positive logic, 1.8Ω max rDS(ON), 120ns max tON, TSSOP-16, ±15V rating | Lower ON-resistance improves THD in audio paths but requires PCB redesign due to different footprint and logic polarity | Choose for ultra-low distortion audio or high-precision instrumentation where layout change is acceptable |
Compared with MAX4612ESE+ and ADG1412BRUZ, the DG412DYZ-T offers unique negative-logic compatibility, proven latch-up immunity in harsh environments, and seamless DG212 replacement capability-making it optimal for legacy industrial upgrades and mixed-voltage systems requiring robust analog signal routing without logic translation.

FAQ
What is the logic polarity of the DG412DYZ-T control inputs?
The DG412DYZ-T uses negative logic: a logic "0" (≤0.8V) turns each switch ON, while a logic "1" (≥2.4V) turns it OFF. This matches the DG212 family and simplifies integration with open-collector drivers or systems requiring active-low enable signals. The DG412DYZ-T datasheet specifies this behavior in the Truth Table on page 2, confirming identical logic polarity across all four INx pins.
Can the DG412DYZ-T operate from a single +12V supply?
Yes, the DG412DYZ-T supports single-supply operation from +5V to +44V. For +12V use, connect V+ (pin 13) to +12V, V− (pin 4) to 0V (ground), and VL (pin 12) to +5V for TTL compatibility. Analog signals may swing from 0V to +12V, and the DG412DYZ-T maintains ≤80Ω max ON-resistance under these conditions per page 5 of the datasheet.
What is the maximum analog signal voltage the DG412DYZ-T can handle?
The DG412DYZ-T supports analog signals up to ±15V with dual supplies (±15V) or 0V to +12V with single +12V supply, as specified in the Analog Signal Range parameter (±15V min/max at full temperature range). Exceeding ±15V risks exceeding absolute maximum ratings (V+ to V− ≤44V), so the DG412DYZ-T must be used within these bounds to ensure reliability and avoid damage.
How does the DG412DYZ-T differ from the DG411DYZ-T?
The DG412DYZ-T and DG411DYZ-T share identical analog switch cores and package, differing only in logic polarity: DG412DYZ-T uses negative logic (IN=0→ON), while DG411DYZ-T uses positive logic (IN=1→ON). Both offer 35Ω max rDS(ON) and 175ns max tON. The DG412DYZ-T is not interchangeable without logic inversion, as confirmed in the Truth Table on page 2 of the FN3282 datasheet.
Is the DG412DYZ-T RoHS-compliant and suitable for lead-free reflow?
Yes, the DG412DYZ-T carries the "-Z" suffix indicating Pb-free plus anneal construction with 100% matte tin terminations, fully compliant with RoHS Directive 2011/65/EU. It meets J-STD-020 moisture sensitivity level requirements and is qualified for standard Pb-free reflow profiles, as documented in the Ordering Information table and Thermal Information section on page 4 of the DG412DYZ-T datasheet.
