Product details
Overview
DG412DY from Renesas Electronics is a monolithic quad SPST CMOS analog switch with TTL/CMOS-compatible digital inputs, 35Ω max ON-resistance, 175ns max turn-on time, and ±20V dual-supply operation. It serves as a drop-in replacement for DG212 in precision signal routing applications such as data acquisition and sample-and-hold circuits.
For engineers reviewing the DG412DY datasheet, DG412DY pinout, DG412DY application, or DG412DY equivalent, key selection considerations include its negative-logic control (logic "0" = ON), 16-pin SOIC package, low 5pC charge injection, and compatibility with ±5V to ±20V or +5V to +44V single-ended supplies.
Technical Context
The DG412DY implements four independent bilateral SPST switches using a high-voltage silicon-gate CMOS process, eliminating latch-up via epitaxial isolation. Its negative logic architecture-where INx = 0V activates the switch-differentiates it from the DG411 (positive logic) and enables direct interface with legacy DG212-based designs.
Each switch supports bidirectional analog signals up to ±15V with minimal rDS(ON) variation, and features matched source/drain OFF capacitance (9pF typ) and high OFF isolation (68dB at 1MHz), making it suitable for low-distortion multiplexing in audio and instrumentation systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ON-resistance (max) | 35Ω - ensures minimal signal attenuation and gain error in precision analog paths |
| Turn-on time (max) | 175ns - enables fast channel switching in high-speed data acquisition systems |
| Charge injection (typ) | 5pC - reduces settling error and simplifies design of sample-and-hold amplifiers |
| Analog signal range | ±15V - supports full-rail operation with ±15V supplies, ideal for industrial sensor interfaces |
| Supply voltage range | ±5V to ±20V or +5V to +44V - provides flexibility across battery-powered and line-powered equipment |
| Logic compatibility | TTL/CMOS - allows direct interfacing with microcontrollers and FPGAs without level-shifting |
| OFF isolation (typ) | 68dB at 1MHz - suppresses crosstalk between active and inactive channels in multiplexer topologies |
Pinout & Package
DG412DY is housed in a 16-lead narrow-body SOIC (150 mil) package per JEDEC MS-012-AC, with standard thermal resistance θJA = 110°C/W. Pin functions are validated per FN3282 Rev 13.00.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Negative-logic digital control inputs: logic "0" ≤0.8V turns corresponding switch ON |
| 2, 7, 10, 15 | D1–D4 | Drain (output) terminals - bidirectional, matched to source terminals for AC-coupled signals |
| 3, 6, 11, 14 | S1–S4 | Source (input) terminals - interchangeable with drains; support ±15V analog swing |
| 4 | V− | Negative power supply rail - must be connected for dual-supply operation or grounded for single-supply use |
| 5 | GND | Logic ground reference - separate from analog power rails to minimize noise coupling |
| 12 | VL | Logic supply reference - requires 5V for TTL-compatible input thresholds regardless of V+/V− levels |
| 13 | V+ | Positive power supply / substrate terminal - sets upper analog voltage limit and bias for CMOS core |
Key Features
| Feature | Design Value |
|---|---|
| Bilateral SPST switches | Four fully symmetric analog paths enable true bidirectional signal routing without polarity constraints |
| Low charge injection (5pC typ) | Minimizes voltage glitch on hold capacitors, reducing need for trimming in precision sampling circuits |
| High OFF isolation (68dB) | Prevents signal bleed-through in multi-channel systems, critical for dynamic range preservation |
| Drop-in DG212 replacement | Identical pinout and negative-logic behavior allow direct substitution without PCB or firmware changes |
| Wide supply range (±20V) | Supports both industrial ±15V signal chains and high-voltage test equipment without external level translation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG412BRZ | 44V max supply, 35Ω rDS(ON), but uses positive logic (IN=1 turns ON); SOIC-16 package | Requires logic inversion in control firmware; identical analog performance and pin count | Select ADG412BRZ only if system already uses positive-logic switch control and layout reuse is prioritized |
| MAX4612ESE+ | 20V max supply, 35Ω rDS(ON), negative logic, but rated only to +85°C (same as DG412DY) and lacks Pb-free anneal option | Not suitable for 40VP-P signal handling or RoHS-compliant reflow processes requiring Pb-free plus anneal | Choose MAX4612ESE+ only for cost-sensitive, lower-voltage (<±10V) applications where Pb-free compliance is not required |
Compared with DG412DY, ADG412BRZ demands firmware adaptation due to opposite logic polarity, while MAX4612ESE+ sacrifices voltage headroom and RoHS reflow compatibility-making DG412DY the optimal choice for high-fidelity, high-voltage, and production-ready designs.

FAQ
What is the logic polarity of the DG412DY control inputs?
The DG412DY uses negative logic: a logic "0" (≤0.8V) turns each switch ON, and a logic "1" (≥2.4V) turns it OFF. This matches the DG212 family and differs from the positive-logic DG411. The VL pin must be supplied with 5V to maintain correct TTL-compatible thresholds, regardless of V+/V− levels. DG412DY's truth table is explicitly defined in FN3282 Rev 13.00, Page 2.
Can DG412DY operate from a single +12V supply?
Yes, DG412DY supports single-supply operation from +5V to +44V. For +12V use, connect V+ (Pin 13) to +12V, V− (Pin 4) to ground, and VL (Pin 12) to +5V. Analog signals may swing from 0V to +12V under these conditions, with rDS(ON) rising to 80Ω max. Full ±15V analog range requires dual ±15V supplies. DG412DY's single-supply specs are verified in FN3282, Page 5.
What is the maximum analog signal voltage supported by DG412DY?
DG412DY supports analog signals up to ±15V when operated with ±15V supplies, and up to +12V with a +12V single supply. Its absolute maximum rating is V+ to V− = 44V, permitting 40VP-P signal control. Exceeding ±15V analog swing risks increased rDS(ON) nonlinearity and leakage; actual usable range depends on supply rails and load conditions. DG412DY's VANALOG spec is confirmed in FN3282, Page 4.
Does DG412DY require external pull-up or pull-down resistors on its logic inputs?
No, DG412DY does not require external biasing on IN1–IN4. Its digital inputs draw only ±0.5µA max (IIL/IIH), and thresholds are internally referenced: logic "0" ≤0.8V and logic "1" ≥2.4V with VL = 5V. Direct connection to CMOS or TTL outputs is sufficient. Adding pull-ups/pull-downs may distort switching edges or increase power; DG412DY's input characteristics are fully specified in FN3282, Page 4.
Is DG412DY pin-compatible with DG411DY or DG413DY?
DG412DY shares identical 16-pin SOIC packaging and pinout with DG411DY and DG413DY, but logic polarity differs: DG411DY uses positive logic (IN=1 = ON), DG412DY uses negative logic (IN=0 = ON), and DG413DY mixes both polarities across its four switches. Physical replacement is possible, but firmware or external logic must be modified to match DG412DY's control scheme. Pin compatibility is documented in FN3282, Page 2.
