Product details

Overview

DG417DY-T1-E3 from Vishay Siliconix is a precision single-pole, normally-closed (SPST-NC) CMOS analog switch optimized for bidirectional signal routing in low-power, high-accuracy systems. It delivers 20 Ω on-resistance, ±15 V analog signal range, 100 ns turn-on time, and ultra-low 35 nW power dissipation - enabling use in battery-powered instrumentation and portable test equipment where leakage, distortion, and board space are critical.

For engineers reviewing the DG417DY-T1-E3 datasheet, DG417DY-T1-E3 pinout, DG417DY-T1-E3 application, or DG417DY-T1-E3 equivalent, key selection criteria include guaranteed break-before-make timing (in DG419 only), dual-supply operation up to ±20 V, SOIC narrow package compatibility, and sub-nA off-state leakage at full temperature range - all validated per Vishay S10-1528-Rev. G.

Technical Context

The DG417DY-T1-E3 implements a high-voltage silicon gate (HVSG) process to achieve robust ±44 V supply rating and latchup immunity via epitaxial layer isolation. Its control logic is active-low: logic "0" (≤ 0.8 V) enables conduction, while logic "1" (≥ 2.4 V) disables the switch - opposite to DG418's polarity.

Each channel supports symmetrical analog conduction with no polarity dependence; signal paths block up to the applied supply rails when off. Charge injection is specified at 60 pC, and off-isolation exceeds –60 dB across 1 MHz–10 MHz, supporting precision sample-and-hold and multiplexed sensor front-ends.

Key Specifications

Pinout & Package

DG417DY-T1-E3 is housed in an 8-pin narrow SOIC (MS-012 / JEDEC MO-153) package measuring 4.9 mm × 3.9 mm × 1.5 mm, with 1.27 mm lead pitch and gull-wing leads. Pin 1 is marked by a beveled corner or dot.

Pin/Terminal	Circuit Role	Design Meaning
1 (IN)	Digital control input	Active-low enable: logic "0" (≤ 0.8 V) turns switch ON; TTL/CMOS compatible
2 (S)	Source terminal	Bidirectional analog I/O node - connects to signal source or load depending on system topology
3 (D)	Drain terminal	Bidirectional analog I/O node - forms switched path with S; no intrinsic directionality
4 (V−)	Negative supply rail	Reference for negative analog swing and internal bias; must be connected even in single-supply use
5 (GND)	Ground reference	Logic ground and substrate reference; separate from analog signal return in mixed-signal layouts
6 (V+)	Positive supply rail	Reference for positive analog swing and internal charge pump; supports up to +44 V absolute max
7 (VL)	Logic supply voltage	Independent 5 V logic rail - decouples digital switching noise from analog supplies
8 (NC)	No-connect	Internally unused; must remain unconnected and unstubbed per datasheet guidance

Key Features

Equivalent & Alternatives

The following parts are listed as comparable options for similar analog switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MAX4617EUA+	SPST-NC, 35 Ω R_DS(on), 125 ns t_on, ±15 V range, same SO-8 package	Higher on-resistance increases gain error in precision gain-setting networks	Select when lower cost outweighs 15 Ω R_DS(on) penalty and 25 ns slower switching is acceptable
ADG1419BRMZ	SPDT, 1.3 Ω R_DS(on), 120 ns t_on, ±15 V range, 10-lead MSOP package	SPDT configuration and smaller footprint require PCB redesign; lower R_DS(on) improves SNR in low-Z paths	Select for higher performance in new designs where layout revision is feasible and on-resistance dominates error budget

Compared with MAX4617EUA+, DG417DY-T1-E3 offers 15 Ω lower on-resistance and 25 ns faster switching for tighter gain accuracy and timing resolution; compared with ADG1419BRMZ, it trades 1.3 Ω R_DS(on) for proven SO-8 compatibility and NC-only simplicity in fail-safe paths.

FAQ

What is the maximum supply voltage rating for DG417DY-T1-E3?

DG417DY-T1-E3 has an absolute maximum supply rating of ±44 V referenced to V−, with dual-supply operation supported from ±5 V to ±20 V. This rating is achieved via Vishay's high-voltage silicon gate (HVSG) process and is validated per Absolute Maximum Ratings table in S10-1528-Rev. G. Exceeding ±44 V risks permanent damage, even momentarily.

Does DG417DY-T1-E3 support single-supply operation?

Yes, DG417DY-T1-E3 supports single-supply operation from 5 V to 40 V, with V− tied to ground. The analog signal range becomes 0 V to V+, and logic supply VL remains at 5 V. Performance parameters such as R_DS(on) (40 Ω typical) and t_on (110 ns) are specified under these conditions in the unipolar section of the datasheet.

What is the function of the NC pin (Pin 8) on DG417DY-T1-E3?

Pin 8 is a no-connect (NC) terminal with no internal connection. Per Vishay S10-1528-Rev. G, it must remain unconnected and unstubbed on the PCB. Routing traces to or placing vias near Pin 8 may introduce parasitic coupling or contamination risk; the DG417DY-T1-E3 operates correctly with Pin 8 floating and unpopulated.

How does DG417DY-T1-E3 differ from DG418DY-T1-E3 in control logic?

DG417DY-T1-E3 uses active-low control logic: IN = logic "0" (≤ 0.8 V) turns the switch ON, while IN = logic "1" (≥ 2.4 V) turns it OFF. DG418DY-T1-E3 is its complementary counterpart with active-high logic. This inversion is explicitly defined in the Truth Table on page 1 of S10-1528-Rev. G and affects direct substitution without level-shifting.

Is DG417DY-T1-E3 RoHS-compliant?

Yes, DG417DY-T1-E3 is RoHS-compliant, as confirmed by the "-E3" suffix in the ordering information (page 2 of S10-1528-Rev. G), which denotes lead-free terminations per JEDEC J-STD-609. The device meets EU RoHS Directive 2011/65/EU and is exempt from exemption 7a (lead in high-melting-temperature type solders) due to its matte tin finish.
