Product details
Overview
DG411DY-T from Renesas Electronics is a monolithic quad SPST CMOS analog switch with TTL/CMOS-compatible digital inputs, 35Ω max ON-resistance, <175ns turn-on time, and ±20V dual-supply operation. It serves as a drop-in replacement for DG211-series switches in precision signal routing applications such as data acquisition and sample-and-hold circuits.
For engineers reviewing the DG411DY-T datasheet, DG411DY-T pinout, DG411DY-T application, or DG411DY-T equivalent, key selection criteria include its bilateral analog switching capability, low charge injection (5pC typ), 44V max supply range, and SOIC-16 package compatibility with industrial temperature operation (-40°C to +85°C).
Technical Context
The DG411DY-T implements four independent SPST switches using a high-voltage silicon-gate CMOS process, enabling 44V maximum V+–V− differential and latch-up immunity via epitaxial isolation. Its logic control uses negative-true polarity: INx = 0V–0.8V turns the corresponding switch ON.
Each switch supports bidirectional analog signals up to ±15V with minimal rDS(ON) variation across the range. The device operates from single supplies (5V–44V) or split supplies (±5V–±20V), with VL pin referenced to 5V for TTL-level compatibility regardless of main supply configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ON-Resistance (max) | 35Ω at ±15V analog swing - ensures minimal signal attenuation and gain error in precision amplifier or ADC front-end paths |
| Turn-On Time (max) | 175ns at ±15V supplies - enables high-speed multiplexing in >5MHz sampling systems |
| Charge Injection (typ) | 5pC - reduces settling error and pedestal distortion in sample-and-hold and switched-capacitor circuits |
| Analog Signal Range | ±15V with ±20V supplies - supports full-rail signal handling in industrial sensor interfaces and audio line drivers |
| Supply Voltage Range | Single: +5V to +44V; Split: ±5V to ±20V - accommodates legacy 5V logic and high-voltage industrial rails without level-shifting |
| Logic Compatibility | TTL/CMOS inputs (0.8V low / 2.4V high thresholds) - interoperable with microcontrollers, FPGAs, and legacy logic families |
| Leakage Current (max) | ±5nA over temperature - preserves accuracy in high-impedance sensor conditioning and battery-powered metering |
Pinout & Package
Package: 16-lead SOIC (150 mil), RoHS-compliant, JEDEC MS-012-AC compliant, body dimensions 10.0 mm × 4.0 mm × 1.75 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Negative-true logic controls: 0V–0.8V activates respective SPST switch; compatible with 3.3V/5V microcontroller GPIO |
| 2, 7, 10, 15 | D1–D4 | Drain (output) terminals - bidirectional; connect to load, ADC input, or downstream signal path |
| 3, 6, 11, 14 | S1–S4 | Source (input) terminals - bidirectional; route analog sources (sensors, DACs, audio lines) to selected outputs |
| 4 | V− | Negative supply rail - must be connected even in single-supply mode (tied to GND); defines lower analog voltage limit |
| 5 | GND | Logic ground reference - separate from analog return; critical for noise isolation in mixed-signal layouts |
| 12 | VL | Logic reference voltage - fixed at 5V (not V+ or V−); enables TTL compatibility across all supply configurations |
| 13 | V+ | Positive supply rail - substrate connection; sets upper analog voltage limit and powers internal bias circuitry |
Key Features
| Feature | Design Value |
|---|---|
| Bilateral SPST switching | Enables true AC-coupled signal routing without polarity constraints - essential for audio, instrumentation, and sensor front-ends |
| Low ON-resistance flatness | ±15V analog input range yields <10% rDS(ON) variation - maintains channel matching in multi-channel data loggers |
| Split/single supply flexibility | V+ and V− pins accept ±5V to ±20V or +5V to +44V - eliminates need for external DC-DC converters in portable or industrial designs |
| Reduced charge injection | 5pC typical - minimizes hold-step error in 16-bit+ sample-and-hold circuits without external correction networks |
| Latch-up immunity | Epitaxial layer prevents destructive latch-up under transient overvoltage - improves reliability in harsh ESD environments |

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 |
|---|---|---|---|
| MAX4611ESE+ | Higher 45Ω max rDS(ON); 200ns tON; requires external VL bypass; no Pb-free SOIC option | Less suitable for low-distortion audio or high-speed DAQ where ON-resistance flatness and speed are critical | Select DG411DY-T when ≤35Ω rDS(ON) and ≤175ns tON are required across full ±15V analog range |
| ADG1411BRUZ | Lower 1.8Ω rDS(ON); 125ns tON; 36V max supply; requires 3.3V logic supply; higher cost | Better for ultra-low-loss precision instrumentation but incompatible with 5V-only logic systems | Choose DG411DY-T for cost-sensitive industrial designs needing TTL compatibility and proven DG211 upgrade path |

FAQ
What is the logic polarity of the DG411DY-T control inputs?
The DG411DY-T uses negative-true logic: a logic low (0V–0.8V) on IN1–IN4 turns the corresponding SPST switch ON, while a logic high (≥2.4V) turns it OFF. This matches the DG211 family behavior and simplifies drop-in replacement in existing designs. The VL pin must be held at 5V to maintain correct threshold referencing regardless of V+/V− supply configuration. DG411DY-T's truth table is explicitly defined in its datasheet Figure 1.
Can the DG411DY-T operate from a single 12V supply?
Yes, the DG411DY-T supports single-supply operation from +5V to +44V. For 12V use, connect V+ to +12V, V− to GND (Pin 4), and VL to +5V (Pin 12). Analog signals may swing from 0V to 12V, with rDS(ON) rising to 80Ω max at full load. DG411DY-T maintains TTL compatibility and fast switching (250ns tON max) under these conditions, as verified in the datasheet's single-supply electrical specifications table.
What is the maximum analog signal voltage the DG411DY-T can handle?
The DG411DY-T supports analog signals up to ±15V when operated from ±20V supplies, or 0V to +12V with a +12V single supply. Its absolute maximum rating is V+–V− ≤ 44V, permitting 40VP-P signal control. Exceeding ±15V analog swing increases rDS(ON) nonlinearity and leakage; the datasheet specifies guaranteed performance only within the ±15V range. DG411DY-T's robust 44V rating ensures margin against transients in industrial environments.
How does the DG411DY-T compare to the DG412DY-T in terms of logic compatibility?
The DG411DY-T and DG412DY-T share identical analog switch characteristics but differ only in logic polarity: DG411DY-T uses negative-true logic (low = ON), while DG412DY-T uses positive-true logic (high = ON). Both are pin-compatible SOIC-16 devices with identical rDS(ON), switching speed, and supply ranges. DG411DY-T is specified as a direct upgrade for DG211, whereas DG412DY-T replaces DG212 - selection depends solely on host controller logic convention.
Is the DG411DY-T RoHS-compliant and lead-free?
Yes, the DG411DY-T is RoHS-compliant and offered in a Pb-free SOIC package (M16.15) with 100% matte tin plating, qualified for reflow soldering per IPC/JEDEC J-STD-020. The "-T" suffix denotes tape-and-reel packaging. Renesas' Pb-free anneal process ensures compatibility with both SnPb and Pb-free assembly processes. DG411DY-T's compliance documentation and reflow profile are available on the Renesas website.
