Product details
Overview
DG417DY+ from Maxim Integrated is a precision SPST analog switch with normally closed (NC) configuration, fabricated in a 44V silicon-gate CMOS process. It delivers guaranteed on-resistance matching ≤3Ω, on-resistance flatness ≤4Ω over signal range, and charge injection ≤10pC max - enabling high-fidelity signal routing in sample-and-hold circuits and audio systems operating from ±4.5V to ±20V or +10V to +30V supplies.
For engineers reviewing the DG417DY+ datasheet, DG417DY+ pinout, DG417DY+ application, or DG417DY+ equivalent, this device is selected for low-leakage, rail-to-rail analog switching in battery-operated test equipment, military radios, and PBX signal paths where sub-5nA off-leakage at +85°C and 175ns max tON are critical design requirements.
Technical Context
The DG417DY+ implements a single-pole/single-throw (SPST), normally closed analog switch topology with TTL/CMOS-compatible logic control. Its internal architecture ensures symmetrical conduction in both directions and guarantees RDS(ON) match and flatness only under bipolar-supply operation (±4.5V to ±20V), per datasheet Note 4.
It features integrated ESD protection (2000V min per Method 3015.7), rail-to-rail analog signal handling, and logic-level translation via dedicated VL pin. Switching performance is characterized with 300Ω load and 35pF capacitance, yielding tON ≤175ns and tOFF ≤145ns at ±15V supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(ON) | 35Ω max at +25°C - ensures minimal signal attenuation in precision analog paths |
| ∆RDS(ON) | 3Ω max between channels - enables matched gain/attenuation in dual-path systems |
| RFLAT(ON) | 4Ω max over full analog range - maintains consistent channel response across ±15.5V input swing |
| Charge Injection | 10pC max - limits voltage glitch in sample-and-hold hold capacitors |
| ID(OFF) @ +85°C | <5nA - preserves DC accuracy in high-impedance sensor front-ends |
| tON/tOFF | 175ns/145ns max - supports >5MHz switching in communications and test instrumentation |
| Supply Range | ±4.5V to ±20V (bipolar) or +10V to +30V (single) - accommodates industrial and battery-powered rails |
Pinout & Package
Package: 8-pin SOIC (Small Outline Integrated Circuit), RoHS-compliant, surface-mountable with standard JEDEC MS-012AC footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Analog Source (S) | Normally closed switch terminal - connects to load when IN = LOW |
| 2 | No Internal Connection (N.C.) | Unused pin - must be left floating or grounded per layout best practice |
| 3 | GND | Logic ground reference - separate from analog V− but tied internally to substrate |
| 4 | V+ | Analog positive supply - supports up to +30V single or +20V bipolar operation |
| 5 | VL | Logic supply input - set to +5V for TTL compatibility or to V+ for CMOS thresholds |
| 6 | IN | Active-low digital control input - drives internal switch gate; compatible with 0.8V/2.4V logic levels |
| 7 | V− | Analog negative supply - supports down to −20V; required for bipolar operation |
| 8 | D | Analog Drain (common) terminal - bidirectional signal path shared with S when closed |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed RDS(ON) matching | ≤3Ω max between channels - eliminates gain mismatch in differential or dual-channel routing |
| Rail-to-rail analog signal handling | Supports signals from V− to V+ - enables full dynamic range utilization without clipping |
| Low temperature drift leakage | <5nA off-leakage at +85°C - sustains accuracy in extended-temperature industrial environments |
| TTL/CMOS logic compatibility | VL pin allows direct interface to 5V microcontrollers or FPGA I/O without level shifters |
| ESD tolerance | 2000V minimum per Method 3015.7 - enhances robustness during board assembly and field operation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRMZ | SPDT configuration, 1.5Ω RDS(ON), requires ±15V only - no single-supply support | Designed for dual-path routing; lacks NC/NO flexibility of DG417DY+ SPST topology | Select when dual-throw functionality and lower on-resistance outweigh need for single-supply operation. |
| TS5A23157DCUR | Single-supply only (+1.65V to +5.5V), 0.9Ω RDS(ON), 100pC charge injection | Targeted at low-voltage portable audio; unsuitable for ±15V industrial signal chains | Choose only for battery-powered 3.3V/5V systems where high-voltage rail-to-rail capability is unnecessary. |
Compared with ADG1419BRMZ and TS5A23157DCUR, the DG417DY+ uniquely supports both bipolar and single high-voltage supplies while guaranteeing sub-5nA leakage at +85°C - making it the only option among the three qualified for precision, wide-temperature, high-voltage analog switching.

FAQ
What is the maximum allowable supply voltage for DG417DY+?
The DG417DY+ supports absolute maximum ratings of V+ ≤ +44V referenced to V−, with recommended operating ranges of ±4.5V to ±20V (bipolar) or +10V to +30V (single supply). Exceeding these ranges risks permanent damage per Absolute Maximum Ratings table in the datasheet. The DG417DY+ must never operate with V+ − V− > +44V.
Does DG417DY+ support single-supply operation?
Yes, DG417DY+ supports single-supply operation from +10V to +30V with V− connected to ground. In this mode, analog signals swing from 0V to V+, and logic inputs remain compatible via the VL pin. However, RDS(ON) matching and flatness specifications are guaranteed only under bipolar-supply conditions per datasheet Note 4.
What is the function of the VL pin on DG417DY+?
The VL pin on DG417DY+ sets the logic threshold reference voltage. When tied to +5V, it enables TTL-compatible input levels (0.8V/2.4V); when tied to V+, it enables CMOS-compatible thresholds. This pin decouples logic interface voltage from analog supply rails, allowing independent optimization of digital control and analog signal integrity.
How does DG417DY+ handle overvoltage conditions on analog pins?
DG417DY+ includes internal ESD diodes that clamp analog pin voltages to V+ + 0.3V and V− − 0.3V. For sustained overvoltage protection beyond Absolute Maximum Ratings, external series diodes are recommended per Figure 1 in the datasheet - reducing analog swing by ~1V but preserving low RDS(ON) and leakage performance.
Is DG417DY+ pin-compatible with older DG417 variants?
Yes, DG417DY+ maintains identical 8-pin SOIC pinout and electrical behavior with legacy DG417C/D and DG417DJ parts. It is a plug-in upgrade offering improved RDS(ON) matching (3Ω vs. unspecified), lower charge injection (10pC vs. 30pC), and enhanced off-leakage (<5nA vs. 20nA at +85°C), with no PCB or firmware changes required.
