Product details
Overview
DG411MY/PR from Maxim Integrated is a quad, normally closed (NC), single-pole/single-throw (SPST) analog switch designed for precision signal routing in high-reliability systems. It features 35Ω max on-resistance, <5nA off-leakage at +85°C, and 10pC max charge injection, operating from ±4.5V to ±20V bipolar or +10V to +30V single supply - ideal for military radios and guidance & control systems.
For engineers reviewing the DG411MY/PR datasheet, DG411MY/PR pinout, DG411MY/PR application, or DG411MY/PR equivalent, key selection criteria include guaranteed RDS(ON) matching (≤3Ω), rail-to-rail analog signal handling (±15.5V), TTL/CMOS logic compatibility, and -55°C to +125°C extended temperature operation.
Technical Context
The DG411MY/PR implements four independent NC analog switches fabricated using a 44V silicon-gate process, enabling robust operation across wide supply ranges. Its architecture guarantees matched on-resistance between channels and flat on-resistance (Δ4Ω max) over the full analog signal range, critical for precision sample-and-hold and audio routing.
Switching is controlled by TTL/CMOS-compatible digital inputs referenced to VL (typically +5V), with logic thresholds fixed at VINH = 2.4V and VINL = 0.8V. The device supports unbalanced supplies (e.g., +24V/–5V) and includes internal ESD protection rated to 2000V per Method 3015.7.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RDS(ON)) | 45Ω max at ±15V - ensures minimal signal attenuation and gain error in precision analog paths |
| RDS(ON) Match | 3Ω max between channels - enables accurate channel-to-channel signal balancing |
| On-Resistance Flatness | Δ4Ω max over ±15.5V range - maintains consistent gain and linearity across full signal swing |
| Off-Leakage Current | <5nA at +85°C - preserves accuracy in high-impedance sample-and-hold and sensor interfaces |
| Charge Injection | 10pC max - minimizes voltage glitch and settling time in switched-capacitor circuits |
| Supply Range | ±4.5V to ±20V bipolar or +10V to +30V single - supports legacy and ruggedized power architectures |
| Operating Temperature | –55°C to +125°C - qualified for aerospace, defense, and industrial underhood applications |
Pinout & Package
DG411MY/PR is supplied in a 16-pin narrow SO package (S16-1 footprint), with exposed pad not present - distinct from QFN variants. Pin functions are electrically identical across DG411 family members.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (Pins 15,14,7,6) | Digital Control Input | Active-low logic controls NC switch state; low = ON (closed), high = OFF (open) |
| S1–S4 (Pins 1,16,9,8) | Analog Source Terminal | Low-impedance connection point for analog signal source side of each switch |
| D1–D4 (Pins 2,15,10,7) | Analog Drain Terminal | Low-impedance connection point for analog signal drain side of each switch |
| V+, V− (Pins 13, 4) | Analog Supply Rails | Define analog signal range; substrate tied to V+ for latch-up immunity |
| GND (Pin 5) | Ground Reference | Return path for logic and analog ground currents; separate from analog signal ground |
| VL (Pin 12) | Logic Supply Voltage | Reference for input logic thresholds; must be +5V for TTL compatibility or tied to V+ for CMOS |
Key Features
| Feature | Design Value |
|---|---|
| Normally Closed (NC) Configuration | Ensures fail-safe signal continuity during power loss or logic fault - critical in safety-critical guidance systems |
| Rail-to-Rail Signal Handling | Supports analog signals from V− to V+ (±15.5V typical) without clipping or distortion |
| TTL/CMOS Logic Compatibility | Accepts standard 0.8V/2.4V logic thresholds with ≤1µA input current - simplifies interface to microcontrollers and FPGAs |
| Low Power Consumption | 35µW max total supply current - enables battery operation in portable test equipment |
| ESD Tolerance | 2000V minimum per Method 3015.7 - enhances robustness in handling and field deployment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG411BRZ | 44V supply max; 35Ω RDS(ON); –40°C to +85°C temp range; no NC default state | Lacks fail-safe NC behavior; unsuitable for power-loss-critical guidance paths | Select only when NC functionality is unnecessary and industrial temp range suffices |
| TS5A3154DCUR | Single-supply only (+1.65V to +5.5V); 0.9Ω RDS(ON); 100MHz bandwidth; +85°C max | Optimized for low-voltage portable audio, not high-voltage precision analog routing | Use only in battery-powered consumer gear where voltage and temp range are constrained |
Compared with ADG411BRZ and TS5A3154DCUR, DG411MY/PR uniquely delivers NC default state, extended –55°C to +125°C operation, and bipolar supply support - making it irreplaceable in aerospace and defense signal routing where fail-safe continuity and environmental resilience are mandatory.

FAQ
What does the "/PR" suffix indicate in DG411MY/PR?
The "/PR" suffix denotes tape-and-reel packaging per Maxim's ordering convention, indicating the DG411MY/PR is supplied in industry-standard 16-pin narrow SO carrier tape with 2.5k-unit reels. This format supports automated SMT placement and is traceable to the original wafer lot and assembly batch, ensuring consistency for high-reliability programs using DG411MY/PR.
Is DG411MY/PR pin-compatible with standard DG411 variants like DG411CY?
Yes, DG411MY/PR shares identical pinout, electrical characteristics, and functional behavior with other DG411 variants in 16-pin narrow SO packages, including DG411CY and DG411DY. All share the same S16-1 footprint, terminal assignments, and truth table - enabling direct substitution where extended temperature qualification is required, without PCB redesign.
How does the normally closed (NC) configuration of DG411MY/PR improve system safety?
The NC configuration of DG411MY/PR ensures analog signal continuity when power is absent or logic inputs are floating or invalid - a critical fail-safe feature in guidance & control systems. In contrast to NO switches, DG411MY/PR maintains signal path integrity during brownouts, reset events, or FPGA configuration glitches, directly supporting MIL-STD-883B reliability requirements for DG411MY/PR.
Can DG411MY/PR operate with unbalanced supplies such as +24V and –5V?
Yes, DG411MY/PR supports unbalanced supplies - the absolute maximum rating requires only that V+ – V− ≤ 44V. Operation at +24V/–5V (29V differential) is fully within specification and maintains all key parameters including RDS(ON), leakage, and switching speed. This flexibility allows DG411MY/PR to interface with legacy power domains without external level-shifting.
What is the role of the VL pin on DG411MY/PR, and how should it be connected?
The VL pin on DG411MY/PR sets the reference voltage for logic input thresholds. For TTL compatibility, connect VL to +5V; for CMOS-level operation, tie VL to V+. Leaving VL unconnected or floating violates specifications and may cause erratic switching. This requirement applies identically across all DG411MY/PR operating conditions and is verified in the device's truth table and timing diagrams.
