Product details
Overview
DG417CY+T from Maxim Integrated is a precision, normally closed (NC), single-pole/single-throw (SPST) analog switch IC designed for high-fidelity signal routing in rail-to-rail, bipolar or single-supply systems. It features guaranteed 35Ω max on-resistance, <5nA off-leakage at +85°C, 10pC max charge injection, and operates from ±4.5V to ±20V or +10V to +30V supplies - used in sample-and-hold circuits and audio signal routing where low distortion and channel matching are critical.
For engineers reviewing the DG417CY+T datasheet, DG417CY+T pinout, DG417CY+T application, or DG417CY+T equivalent, this page delivers verified electrical parameters, package mapping to 8-pin SOIC, truth-table–validated switching behavior, thermal leakage performance, and direct alternatives with documented functional trade-offs for precision analog switching design.
Technical Context
The DG417CY+T implements a silicon-gate CMOS SPST switch architecture with integrated level-shifting logic interface, enabling TTL/CMOS-compatible control across wide supply ranges. Its on-resistance flatness (≤4Ω max) and matching (≤3Ω max) are guaranteed only under bipolar-supply operation, reflecting optimized channel uniformity over the full analog signal range (±15.5V).
Charge injection (≤10pC) and off-leakage (<5nA at +85°C) are specified and tested per Method 3015.7 ESD stress (≥2000V), confirming suitability for battery-operated and military-grade systems requiring long-term signal integrity and low power consumption (35µW max).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Normally closed (NC) SPST analog switch - conducts when logic input is low; essential for fail-safe signal path continuity. |
| RDS(ON) Max | 35Ω at +25°C - ensures minimal insertion loss and voltage drop in precision DC/AC signal paths up to ±15.5V. |
| tON/tOFF Max | 175ns / 145ns - supports high-speed multiplexing in test equipment and communications systems without timing skew. |
| Charge Injection | 10pC max - limits voltage glitch in sample-and-hold circuits, preserving ADC accuracy after switching. |
| Off-Leakage @ +85°C | <5nA - maintains signal integrity in high-impedance sensor interfaces and battery-powered systems over temperature. |
| Supply Range | ±4.5V to ±20V (bipolar) or +10V to +30V (single) - enables flexible integration into industrial, telecom, and military power architectures. |
| ESD Rating | 2000V min per Method 3015.7 - provides robust handling during PCB assembly and field operation without external protection. |
Pinout & Package
Package: 8-pin SOIC (Small Outline Integrated Circuit), surface-mount, RoHS-compliant, JEDEC MS-012 variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Analog Source (S) | Normally closed switch terminal - connects to load/signal path when IN = low; rail-to-rail capable. |
| 2 | No Internal Connection (N.C.) | Unused pad; must be left floating or grounded per layout best practice - no electrical function. |
| 3 | GND | Logic ground reference - separate from analog V−; decoupling required near pin for noise immunity. |
| 4 | V+ | Analog positive supply - accepts +10V to +30V (single) or up to +44V absolute max; powers analog channel. |
| 5 | VL | Logic supply input - tied to +5V for TTL compatibility or to V+ for CMOS-level logic thresholds. |
| 6 | IN | Active-low digital control input - drives internal level shifter; compatible with 0.8V/2.4V logic thresholds. |
| 7 | V− | Analog negative supply - accepts −4.5V to −20V (bipolar) or 0V (single supply); defines lower analog rail. |
| 8 | D | Analog Drain terminal - common output node; bidirectional conduction with S; handles ±15.5V signals. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed RDS(ON) match | ≤3Ω max between channels - enables matched gain/attenuation in dual-path instrumentation front-ends. |
| Rail-to-rail signal handling | Supports analog signals from V− to V+ - eliminates clipping in audio routing and sensor conditioning stages. |
| Low power consumption | 35µW max - extends battery life in portable test gear and remote monitoring devices. |
| TTL/CMOS logic compatibility | Accepts standard 5V logic levels at VL = 5V - simplifies interface with microcontrollers and FPGAs without level shifters. |
| Improved off-isolation | 68dB min at 1MHz - suppresses crosstalk between adjacent channels in dense multiplexer layouts. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617EUA+ | Lower RDS(ON) (15Ω typ), but only rated to +85°C and lacks guaranteed RFLAT(ON) spec. | Better for low-voltage, high-speed digital signal switching; less suitable for precision ±15V analog paths. | Select MAX4617EUA+ only if on-resistance priority outweighs flatness and leakage guarantees. |
| ADG1419BRMZ | SPDT configuration (not SPST), 1.5Ω RDS(ON), but higher charge injection (12pC) and no NC/NO variant differentiation. | Requires redesign for SPDT use case; superior for low-RDS(ON) multiplexing, not fail-safe NC routing. | Choose ADG1419BRMZ only when SPDT topology and sub-2Ω resistance justify layout change and leakage tolerance. |
Compared with DG417CY+T, MAX4617EUA+ trades guaranteed flatness and high-temp leakage for lower on-resistance, while ADG1419BRMZ offers superior RDS(ON) but forces SPDT topology and sacrifices NC-specific fail-safe behavior - neither is pin-compatible nor drop-in.

FAQ
What is the operating temperature range for DG417CY+T?
The DG417CY+T is rated for −40°C to +85°C operation, confirmed in the Ordering Information table and Electrical Characteristics sections. This extended temperature grade makes it suitable for industrial and military applications where ambient conditions exceed commercial-grade limits. The DG417CY+T's leakage current remains below 5nA at +85°C, ensuring reliable performance across its full range.
Is DG417CY+T pin-compatible with the original DG417CJ?
Yes, DG417CY+T shares identical 8-pin SOIC pinout and logic functionality with DG417CJ, including NC pin placement, IN polarity, and V+/V−/GND/S/D assignments. However, DG417CY+T improves RDS(ON) matching (3Ω vs. unspecified in older version) and guarantees RFLAT(ON) - making it a plug-in upgrade per Maxim's "New Features" section.
Does DG417CY+T support single-supply operation?
Yes, DG417CY+T operates from a single +10V to +30V supply, with V− connected to GND. The datasheet specifies analog signal range (0V to V+), on-resistance (40Ω max), and dynamic parameters under single-supply conditions - confirming full functionality without bipolar rails in battery-powered or simplified power systems.
What is the maximum analog signal voltage DG417CY+T can handle?
DG417CY+T supports analog signals from V− to V+, with absolute maximum ratings of V+ ≤ 44V referenced to V−. Under recommended operation (±16.5V supplies), the guaranteed signal range is ±15.5V. Exceeding these voltages risks permanent damage, as clamping diodes activate only within the Absolute Maximum Ratings limits.
How does DG417CY+T achieve low charge injection?
DG417CY+T achieves ≤10pC max charge injection through matched transistor geometry and optimized gate drive timing in its 44V silicon-gate CMOS process. This value is measured per Figure 5 in the datasheet using a 10nF capacitor and zero-source-impedance generator - directly enabling high-accuracy sample-and-hold performance without external correction circuitry.
