Product details
Overview
DG308ADY-T1 from Vishay Siliconix is a quad monolithic SPST CMOS analog switch in normally open configuration, rated for ±15 V analog signal range, 60 Ω on-resistance, and 130 ns turn-on time. It operates from dual ±15 V supplies or single +15 V/0 V, supporting rail-to-rail analog switching in high-speed multiplexing and portable instrumentation.
For engineers reviewing the DG308ADY-T1 datasheet, DG308ADY-T1 pinout, DG308ADY-T1 application, or DG308ADY-T1 equivalent, this device is selected for low-leakage (±0.1 nA off-state), low-power (30 nW), CMOS-compatible control, and TSSOP-16 packaging with guaranteed -40 °C to +85 °C operation.
Technical Context
The DG308ADY-T1 implements four independent bidirectional SPST switches fabricated in Vishay's PLUS-40 CMOS process, enabling 44 V breakdown voltage and latch-up immunity via epitaxial isolation. Each channel conducts equally in both directions when on and blocks up to supply rails when off.
Logic inputs accept high-voltage CMOS thresholds (≤3.5 V for '0', ≥11 V for '1'), ensuring compatibility with TTL and 15 V logic families. Charge injection is limited to -10 pC, and off-isolation reaches 78 dB at 500 kHz - critical for precision signal routing in mixed-signal systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V - supports full rail-to-rail signal handling with dual ±15 V supplies or 0 V to +15 V with single supply |
| Drain-Source On-Resistance | 60 Ω typical - minimizes signal attenuation and distortion in precision analog paths |
| Turn-On Time | 130 ns - enables high-speed multiplexing up to ~1 MHz without significant settling delay |
| Off-Leakage Current | ±0.1 nA max - preserves accuracy in high-impedance sensor interfaces and sample-hold circuits |
| Supply Current | 10 µA max per supply - ensures ultra-low static power for battery-powered applications |
| Charge Injection | -10 pC - reduces voltage glitch in switched-capacitor and ADC front-end designs |
| Off-Isolation | 78 dB at 500 kHz - suppresses crosstalk between channels in multi-channel data acquisition |
Pinout & Package
Package: 16-lead TSSOP (JEDEC MO-153, Vishay Doc. 74417), body dimensions 5.00 × 4.40 × 1.20 mm, 0.65 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | Digital Input (IN1–IN4) | CMOS/TTL-compatible control lines; logic '1' (≥11 V) closes corresponding switch |
| 2, 6, 10, 14 | Source (S1–S4) | Switch input terminal; bidirectional analog path when enabled |
| 3, 7, 11, 15 | Drain (D1–D4) | Switch output terminal; electrically identical to Source in on-state |
| 4 | V+ | Positive supply rail; must be ≥ |V−| for proper operation; max 44 V differential |
| 8 | GND | Ground reference for digital logic and substrate bias |
| 12 | V− | Negative supply rail; required for bipolar operation; clamps analog signals to rails |
| 16 | NC | No connect - internally unconnected; must be left floating or tied to GND per layout best practice |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional analog conduction | Equal RDS(on) in both directions enables flexible signal routing without polarity constraints |
| Epitaxial latch-up immunity | Prevents destructive parasitic SCR activation under transient overvoltage or ESD stress |
| Low charge injection (-10 pC) | Minimizes voltage step error in sample-and-hold and switched-capacitor filter stages |
| High off-isolation (78 dB) | Reduces inter-channel crosstalk in 4-channel multiplexers used in medical or test equipment |
| Single/dual supply flexibility | Operates from +15 V/0 V or ±15 V - simplifies power architecture in mixed-signal PCBs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | Higher on-resistance (100 Ω), lower supply voltage range (±5 V), SO-16 package only | Not suitable for ±15 V signal routing; better for low-voltage portable systems | Select DG308ADY-T1 when ±15 V analog range and 60 Ω RDS(on) are required |
| ADG1404YRUZ | Lower on-resistance (4.7 Ω), higher cost, 16-lead TSSOP, but requires external VLOGIC supply | Superior performance in precision instrumentation, but adds complexity for logic-level translation | Choose DG308ADY-T1 for cost-sensitive, high-voltage, self-contained CMOS-switching needs |
Compared with MAX4617ESE+ and ADG1404YRUZ, the DG308ADY-T1 delivers optimal balance of ±15 V signal handling, 60 Ω on-resistance, and zero external logic supply requirements - making it ideal for industrial and test equipment where voltage range and simplicity are prioritized over ultra-low RDS(on).

FAQ
What is the operating temperature range for DG308ADY-T1?
The DG308ADY-T1 is specified for -40 °C to +85 °C ambient operation, matching the "D" temperature suffix in Vishay's ordering nomenclature. This range is validated per the Absolute Maximum Ratings table and supported by thermal derating curves showing 6.5 mW/°C reduction above 25 °C. All electrical parameters in the datasheet apply across this full industrial temperature span.
Does DG308ADY-T1 support single-supply operation?
Yes, DG308ADY-T1 supports single-supply operation with V+ = +15 V and V− = 0 V (GND). In this mode, analog signals must remain within 0 V to +15 V to avoid clamping. Performance trade-offs include slightly increased RDS(on) and slower switching versus dual-supply operation, as documented in the Applications section of the datasheet.
What is the maximum analog signal voltage DG308ADY-T1 can handle?
DG308ADY-T1 supports analog signals from V− to V+, with absolute maximum ratings allowing up to 44 V differential between V+ and V−. With ±15 V supplies, the full analog range is -15 V to +15 V. Signals exceeding these rails are clamped by internal diodes - forward current must be limited to 20 mA per diode to prevent damage, per Note (a) in the datasheet.
Is DG308ADY-T1 pin-compatible with DG308ACJ or DG308ADQ?
No - DG308ADY-T1 (16-pin narrow SOIC) has different pin spacing (1.27 mm pitch) and body dimensions than DG308ACJ (16-pin DIP, 2.54 mm pitch) and DG308ADQ (16-pin TSSOP, 0.65 mm pitch). While all share identical logic and analog pin functions, mechanical incompatibility prevents direct PCB replacement without layout revision.
What does the "-T1" suffix indicate in DG308ADY-T1?
The "-T1" suffix denotes tape-and-reel packaging per EIA-481 standard, optimized for automated SMT placement. DG308ADY-T1 contains 2,500 units per reel and is RoHS-compliant (Pb-free terminations), as confirmed in the Ordering Information table and Package Information documents referenced in the datasheet.
