Product details
Overview
DG417DY+T from Maxim Integrated is a precision, normally closed (NC), single-pole/single-throw (SPST) analog switch optimized for rail-to-rail signal routing in ±4.5V to ±20V or +10V to +30V supply systems. It delivers guaranteed 35Ω max on-resistance, <5nA off-leakage at +85°C, and 10pC max charge injection - enabling high-fidelity sample-and-hold and audio signal switching in battery-operated test equipment.
For engineers reviewing the DG417DY+T datasheet, DG417DY+T pinout, DG417DY+T application, or DG417DY+T equivalent, key selection criteria include bipolar/single-supply flexibility, guaranteed RDS(ON) matching across temperature, low leakage in guidance systems, and SO-8 package compatibility with automated PCB assembly.
Technical Context
The DG417DY+T uses a 44V silicon-gate CMOS process to support wide analog signal ranges up to ±15.5V with rail-to-rail operation. Its TTL/CMOS-compatible logic input (VL = 5V) controls conduction between source (S) and drain (D) terminals without polarity dependence, and internal ESD protection meets 2000V per Method 3015.7.
Switching performance is characterized under dual-supply conditions: tON ≤ 175ns and tOFF ≤ 145ns at ±15V, with guaranteed on-resistance flatness (≤4Ω variation over full signal range) and channel-to-channel RDS(ON) match ≤3Ω - critical for multi-channel instrumentation front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RDS(ON)) | 35Ω max at +25°C; ensures minimal signal attenuation in precision DC-coupled paths |
| On-resistance flatness | 4Ω max over full analog range; maintains consistent gain/attenuation across ±15.5V signals |
| Off-leakage current | <5nA at +85°C; preserves accuracy in high-impedance sample-and-hold hold capacitors |
| Charge injection | 10pC max; limits voltage glitch on hold capacitors during switching transitions |
| Supply range | ±4.5V to ±20V or +10V to +30V; supports industrial and military-grade power architectures |
| ESD tolerance | 2000V min per Method 3015.7; enables robust handling in manufacturing and field environments |
| Switching time (tON/tOFF) | 175ns / 145ns max; suitable for 5MHz+ multiplexed data acquisition systems |
Pinout & Package
Package: 8-pin SOIC (SO), RoHS-compliant, surface-mountable with standard reflow profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Analog source (S) | Normally closed terminal; connects to D when IN = LOW; carries full analog signal current |
| 2 | No internal connection (N.C.) | Unused pad; must be left floating or grounded per layout best practices |
| 3 | GND | Logic ground reference; separate from analog supply returns to minimize noise coupling |
| 4 | V+ | Analog positive supply; sets upper rail of bidirectional signal range (e.g., +15V in ±15V system) |
| 5 | VL | Logic supply input; tied to +5V for TTL compatibility or to V+ for CMOS-level control |
| 6 | IN | Active-low logic control input; drives internal gate; compatible with 0.8V/2.4V thresholds |
| 7 | V- | Analog negative supply; sets lower rail (e.g., -15V); enables true bipolar signal handling |
| 8 | D | Analog drain terminal; output node for switched signal; symmetric conduction with S |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed RDS(ON) match | ≤3Ω between channels - essential for matched gain in differential or multi-path systems |
| Rail-to-rail signal handling | Supports analog voltages from V– to V+ - eliminates level-shifting in ±15V sensor interfaces |
| Low power consumption | 35µW max - extends battery life in portable modems and fax machines |
| TTL/CMOS logic compatibility | Accepts standard 5V logic levels without external level translators - simplifies controller interfacing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRMZ | SPDT configuration (1 NC + 1 NO), 4.5Ω RDS(ON), ±15V supply, but higher 15pC charge injection | Requires redesign for SPST-only topologies; better suited for dual-path routing than simple on/off control | Select ADG1419BRMZ only if SPDT functionality and lower on-resistance outweigh charge injection sensitivity |
| TS5A23157DCUR | Single-supply only (+1.65V to +5.5V), 0.9Ω RDS(ON), but limited to 5.5V max analog range and no bipolar capability | Not viable for ±15V industrial or military signal chains; restricted to low-voltage consumer audio | Choose TS5A23157DCUR only for cost-sensitive, single-supply 3.3V systems where rail-to-rail bipolar operation is unnecessary |
Compared with DG417DY+T, ADG1419BRMZ adds SPDT flexibility at the cost of higher charge injection, while TS5A23157DCUR offers ultra-low on-resistance but sacrifices bipolar supply support and high-voltage signal integrity - making DG417DY+T the sole choice for precision ±15V sample-and-hold and military radio signal routing.

FAQ
What is the maximum analog signal voltage range supported by DG417DY+T?
DG417DY+T supports analog signals from V– to V+, with absolute maximum ratings of ±16.5V under bipolar operation and up to +16.5V with V– = 0V in single-supply mode. Per datasheet specifications, the guaranteed operational analog range is ±15.5V at V+ = +16.5V and V– = –16.5V, enabling full rail-to-rail handling in ±15V systems without clipping or distortion.
Is DG417DY+T pin-compatible with older DG417 variants like DG417DJ?
Yes, DG417DY+T is pin-compatible with DG417DJ and other 8-pin SO/DIP variants in the DG417 family. Both share identical SOIC-8 pinout (S, N.C., GND, V+, VL, IN, V–, D), same thermal pad configuration, and identical footprint dimensions (4.9mm × 3.9mm). No PCB layout changes are required when upgrading from DG417DJ to DG417DY+T for enhanced leakage and flatness performance.
Does DG417DY+T require external pull-up or pull-down resistors on the IN pin?
No, DG417DY+T does not require external biasing on the IN pin. Its logic input has specified VIH = 2.4V and VIL = 0.8V thresholds with leakage current ≤±0.5µA, allowing direct connection to standard 5V TTL or CMOS microcontroller GPIOs. Internal design ensures clean switching without external resistors, reducing BOM count and board space in compact designs using DG417DY+T.
How does DG417DY+T perform at elevated temperatures, such as +85°C?
At +85°C, DG417DY+T maintains guaranteed performance: off-leakage current remains <5nA, on-resistance flatness stays ≤4Ω, and RDS(ON) is bounded at 45Ω max. These parameters are 100% tested at maximum rated hot temperature per datasheet Note 5, ensuring reliability in extended-temperature industrial and automotive under-hood applications where DG417DY+T is deployed.
Can DG417DY+T operate with unbalanced supplies, such as +24V and –5V?
Yes, DG417DY+T supports unbalanced supplies per Applications Information section: the difference between V+ and V– must not exceed +44V, and both rails must remain within absolute maximum ratings (V+ ≤ 44V referenced to V–, GND ≤ 25V referenced to V–). A +24V/–5V configuration (29V total) is fully compliant and preserves rail-to-rail signal range from –5V to +24V, making DG417DY+T suitable for custom power architectures in industrial control systems.
