Product details
Overview
DG412DY-T from Renesas Electronics is a monolithic quad SPST CMOS analog switch with TTL/CMOS-compatible digital inputs, 35 Ω max ON-resistance, 175 ns max tON, and ±20 V dual-supply or 5–44 V 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 DG412DY-T datasheet, DG412DY-T pinout, DG412DY-T application, or DG412DY-T equivalent, this page delivers verified electrical specs, SOIC-16 package details, logic polarity confirmation (active-HIGH control), leakage performance (±0.25 nA at 25°C), and real-world switching behavior under ±15 V analog signal swing.
Technical Context
The DG412DY-T implements four independent bilateral SPST switches using a high-voltage silicon-gate CMOS process with epitaxial isolation to prevent latch-up. Its logic polarity-where INx = HIGH turns the switch OFF and INx = LOW turns it ON-is fixed per DG412 family specification and differs from DG411 (active-LOW).
It supports rail-to-rail analog signal handling up to ±15 V with low charge injection (5 pC typ) and maintains <45 Ω rDS(ON) across full temperature range (−40°C to +85°C). The VL pin enables TTL-level compatibility while operating from ±5 V to ±20 V supplies or +5 V to +44 V single supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ON-resistance (max) | 35 Ω at 25°C - ensures minimal signal attenuation and gain error in precision amplifier multiplexing |
| Turn-on time (max) | 175 ns at 25°C - enables sub-microsecond channel switching in high-speed data acquisition |
| Analog signal range | ±15 V - supports full-rail AC-coupled audio and industrial sensor signals without clipping |
| Charge injection (typ) | 5 pC - reduces pedestal error in sample-and-hold stages, easing hold capacitor sizing |
| OFF isolation (typ) | 68 dB at 1 MHz - suppresses crosstalk between adjacent channels in multi-channel instrumentation |
| Supply voltage range | ±5 V to ±20 V or +5 V to +44 V - accommodates legacy bipolar rails and modern wide-range unipolar systems |
| Logic compatibility | TTL/CMOS - interfaces directly with microcontrollers, FPGAs, and legacy logic without level-shifting |
Pinout & Package
DG412DY-T is housed in a 16-lead SOIC (150 mil) package per JEDEC MS-012-AC, with 1.27 mm lead pitch, 10.0 mm × 4.0 mm body, and RoHS-compliant matte tin terminations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs; logic HIGH = switch OFF (DG412-specific active-HIGH polarity) |
| 2, 15, 10, 7 | D1–D4 | Drain (output) terminals; bidirectional current path when switch is ON |
| 3, 14, 11, 6 | S1–S4 | Source (input) terminals; symmetric with drains for AC/bidirectional signal routing |
| 4 | V− | Negative power supply rail; must be connected for dual-supply operation or grounded for single-supply |
| 5 | GND | Logic ground reference; separate from power grounds to minimize noise coupling into control logic |
| 12 | VL | Logic reference voltage; tied to 5 V for TTL compatibility regardless of analog supply rails |
| 13 | V+ | Positive power supply rail (also substrate connection); defines upper analog voltage limit |
Key Features
| Feature | Design Value |
|---|---|
| Drop-in DG212 replacement | Identical pinout and function to DG212, enabling direct upgrade without PCB redesign |
| Bilateral switching | Equal ON-resistance and capacitance in both directions - preserves signal integrity for AC-coupled audio paths |
| Low charge injection | 5 pC typical - minimizes voltage step errors during sampling, critical for 12-bit+ ADC front-ends |
| Latch-up immunity | Epitaxial layer isolation - eliminates risk of destructive latch-up under transient overvoltage conditions |
| Pb-free + anneal construction | RoHS-compliant with 100% matte tin finish - qualified for both SnPb and Pb-free reflow profiles |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4612ESE+ | Higher ON-resistance (45 Ω max), slower tON (250 ns max), same SOIC-16 package | Less suitable for high-speed DAQ; acceptable for audio where bandwidth <100 kHz | Select MAX4612ESE+ only if lower cost outweighs 75 ns speed penalty and 10 Ω resistance increase |
| ADG412BRZ | Active-LOW logic (DG411-style), identical rDS(ON) and switching specs, same SOIC-16 footprint | Requires inverted control signals; unsuitable where existing firmware assumes DG412 polarity | Choose ADG412BRZ only when logic inversion can be implemented in FPGA/microcontroller firmware |
Compared with MAX4612ESE+ and ADG412BRZ, DG412DY-T offers the fastest switching (175 ns tON), lowest ON-resistance (35 Ω), and native DG212-compatible logic polarity-making it optimal for drop-in upgrades and time-critical signal routing where control timing and analog fidelity are co-constrained.

FAQ
What is the logic polarity of DG412DY-T?
The DG412DY-T uses active-HIGH logic control: a logic HIGH (≥2.4 V) at INx turns the corresponding switch OFF, and a logic LOW (≤0.8 V) turns it ON. This polarity matches the DG212 family and differs from DG411 (active-LOW). Confirmed by truth table on page 2 of FN3282 Rev 13.00. DG412DY-T must be driven with inverted control signals relative to DG411-based designs.
Does DG412DY-T support single-supply operation?
Yes, DG412DY-T operates from a single +5 V to +44 V supply. Pin 4 (V−) must be connected to ground, Pin 13 (V+) to the positive rail, and Pin 12 (VL) to +5 V for TTL compatibility. Analog signal range is 0 V to V+ − 2 V (e.g., 0–10 V at +12 V supply), per Electrical Specifications on page 4 of FN3282.
What is the maximum analog signal voltage DG412DY-T can handle?
DG412DY-T supports analog signals from V− to V+, with a maximum differential supply rating of 44 V. In dual-supply mode (e.g., ±15 V), the analog input range is ±15 V. In single-supply mode (+12 V), the range is 0–10 V. Absolute maximum ratings specify V+ to V− ≤ 44 V and analog pins within (V− − 2 V) to (V+ + 2 V), per page 4 of FN3282.
Is DG412DY-T pin-compatible with DG212?
Yes, DG412DY-T is a drop-in replacement for DG212 with identical pinout, electrical behavior, and logic polarity. The datasheet states "DG411 series… are drop-in replacements for the popular DG211 and DG212 series devices" and confirms matching pin assignments and truth tables. DG412DY-T retains the same SOIC-16 footprint (M16.15) as DG212.
What is the thermal resistance (θJA) of DG412DY-T in SOIC package?
The junction-to-ambient thermal resistance (θJA) for DG412DY-T in 16-lead SOIC package is 110°C/W, measured under standard JEDEC test conditions (low effective thermal conductivity board, free air). This value is specified in the Thermal Information table on page 4 of FN3282 Rev 13.00 and applies to the DG412DY variant.
