Product details
Overview
DG417CY+ from Maxim Integrated is a precision CMOS single-pole/single-throw (SPST) analog switch with normally closed (NC) configuration, 35Ω maximum on-resistance, 175ns maximum turn-on time, and guaranteed on-resistance matching ≤3Ω between channels - designed for high-fidelity signal routing in battery-operated test equipment and audio systems.
For engineers reviewing the DG417CY+ datasheet, DG417CY+ pinout, DG417CY+ application, or DG417CY+ equivalent, this device supports rail-to-rail analog signal handling from ±4.5V to ±20V bipolar supplies or +10V to +30V single supply, features <5nA off-leakage at +85°C, and delivers low charge injection (10pC max) critical for sample-and-hold accuracy.
Technical Context
The DG417CY+ implements a silicon-gate CMOS process optimized for analog switching integrity, with internal ESD protection rated to 2000V per Method 3015.7 and guaranteed on-resistance flatness ≤4Ω over full signal range under bipolar operation. Its logic interface accepts TTL/CMOS-compatible inputs referenced to VL.
It operates without latch-up across its full supply range and maintains low power consumption (35µW max) due to sub-1µA supply currents (I+, I−, IL) at +25°C. The device's break-before-make timing is not applicable, as it is an SPST NC switch - no channel interaction or switching sequence dependency exists.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | SPST, normally closed (NC) - conducts when control input is logic low. |
| RDS(ON) Max | 35Ω at +25°C, V± = ±15V - ensures minimal signal attenuation in precision gain paths. |
| ΔRDS(ON) Max | 3Ω matching between channels - enables matched gain/attenuation in dual-path instrumentation. |
| tON / tOFF | <175ns / <145ns - supports high-speed multiplexing up to ~2MHz without settling distortion. |
| Charge Injection | 10pC max - limits voltage glitch in sample-and-hold capacitors ≤100pF to <100mV. |
| Off-Leakage @ +85°C | <5nA - preserves DC accuracy in long-integration sensor front-ends and battery-monitoring circuits. |
| Supply Range | Bipolar ±4.5V to ±20V or single +10V to +30V - accommodates industrial rails and legacy ±15V systems. |
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 analog terminal - connects to load when IN = low; bidirectional conduction path. |
| 2 | No Internal Connection (N.C.) | Unbonded pad; must be left floating - no electrical function or thermal role. |
| 3 | GND | Logic ground reference for VL and digital inputs; separate from analog V− but tied internally in most layouts. |
| 4 | V+ | Analog positive supply - sets upper rail of analog signal range; must be ≥|V−| + 10V for full bipolar operation. |
| 5 | VL | Logic supply input - set to +5V for TTL compatibility or to V+ for CMOS-level logic thresholds. |
| 6 | IN | Active-low digital control input - drives internal gate; compatible with 0.8V/2.4V TTL thresholds. |
| 7 | V− | Analog negative supply - defines lower analog rail; required for bipolar operation and rail-to-rail swing. |
| 8 | D | Analog Drain terminal - fixed connection point; completes NC path with Pin 1 when IN = low. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without clipping - essential for ±10V sensor interfaces and audio line drivers. |

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 (not SPST NC); 4.7Ω RDS(ON); requires dual ±15V or single 12V supply. | Not drop-in: different pinout, logic polarity (active-high), and channel count - requires PCB redesign. | Select only if SPDT functionality and lower on-resistance outweigh layout change cost. |
| TS5A23157DCUR | Single-supply only (1.65V–5.5V); 0.9Ω RDS(ON); no bipolar support; 1.5pC charge injection. | Limited to low-voltage portable electronics; cannot replace DG417CY+ in ±15V industrial or audio systems. | Use only in new 3.3V embedded designs where rail-to-rail analog swing is not required. |
Compared with ADG1419BRMZ and TS5A23157DCUR, the DG417CY+ uniquely supports true bipolar ±20V operation with NC default state and guaranteed matching - making it irreplaceable in legacy test gear, military radios, and high-precision analog signal conditioning where supply flexibility and fail-safe closure are mandatory.

FAQ
What is the operating temperature range for the DG417CY+?
The DG417CY+ is specified for 0°C to +70°C ambient operation, as indicated by the "CY" suffix in its ordering code. It is packaged in an 8-pin SOIC and tested across this commercial temperature range per Maxim's datasheet revision 2. Performance parameters including RDS(ON), leakage, and switching times are guaranteed within this interval. For extended temperature versions, consider DG417DY (–40°C to +85°C) or DG417AK (–55°C to +125°C).
Does the DG417CY+ support single-supply operation?
Yes, the DG417CY+ supports single-supply operation from +10V to +30V. In this mode, connect V− to ground (0V), configure VL to +5V for TTL compatibility, and ensure analog signals remain within the 0V to V+ range. The device maintains rail-to-rail signal handling, 35Ω RDS(ON), and <5nA off-leakage at +85°C - though on-resistance increases slightly versus bipolar operation.
What is the logic polarity of the DG417CY+ control input?
The DG417CY+ features active-low logic control: the switch is ON (closed) when the IN pin is at logic low (≤0.8V), and OFF (open) when IN is at logic high (≥2.4V). This normally closed behavior provides fail-safe signal continuity during power loss or controller reset - a key requirement in guidance systems and PBX line cards where default connectivity is critical.
Can the DG417CY+ be used with unbalanced supplies like +24V and –5V?
Yes, the DG417CY+ supports unbalanced supplies as long as the absolute difference between V+ and V− does not exceed +44V and both pins remain within their Absolute Maximum Ratings (V+ ≤ 44V referenced to V−, GND ≤ 25V referenced to V−). For +24V/–5V operation, analog signals must stay within –5V to +24V, and VL should be set to +5V. Verified performance data confirms stable RDS(ON) and leakage under such conditions.
Is the DG417CY+ pin-compatible with older DG417 variants?
Yes, the DG417CY+ is a plug-in upgrade for industry-standard DG417 devices in 8-pin SOIC packages. It shares identical pinout, footprint, and logic interface with legacy DG417C/D and DG417DJ/DY variants. Key improvements - including 3Ω RDS(ON) matching, <5nA off-leakage at +85°C, and 10pC charge injection - are achieved without altering PCB layout or firmware.
