Product details
Overview
DG9461DY-T1-E3 from Vishay Siliconix is a low-voltage single-pole/double-throw (SPDT) CMOS analog switch in SOIC-8 package, designed for high-performance signal routing in portable systems. It delivers rDS(on) = 30 Ω (typ) at V+ = 5 V, tON = 35 ns, tOFF = 20 ns, ICOM(on) ≤ 200 pA max, and operates from +2.7 V to +12 V - ideal for battery-powered test equipment and cellular phone front-end switching.
For engineers reviewing the DG9461DY-T1-E3 datasheet, DG9461DY-T1-E3 pinout, DG9461DY-T1-E3 application, or DG9461DY-T1-E3 equivalent, key selection criteria include guaranteed break-before-make timing, low charge injection (QINJ = 1–2 pC), TSOP-6/SOIC-8 dual-package availability, RoHS-compliant Pb-free termination (E3 suffix), and ±20 mA continuous current rating.
Technical Context
The DG9461DY-T1-E3 implements a monolithic CMOS SPDT switch fabricated on Vishay's BCD-15 low-voltage process, with epitaxial latchup protection and ESD robustness >2000 V (HBM, Method 3015.7). Its logic interface accepts TTL/CMOS-compatible inputs (VIL ≤ 0.8 V, VIH ≥ 2.4 V) across the full −40 °C to +85 °C operating range.
Each channel conducts bidirectionally when ON and blocks signals up to the supply rail when OFF. Break-before-make operation is guaranteed by design, eliminating signal shorting during state transitions - critical for sample-and-hold and multiplexed sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V+ Range | +2.7 V to +12 V - supports single-supply operation in 3.3 V and 5 V systems without level-shifting. |
| rDS(on) | 30 Ω (typ) at V+ = 5 V - minimizes signal attenuation and voltage drop in precision analog paths. |
| tON / tOFF | 35 ns / 20 ns - enables fast multiplexing in data acquisition and communication signal routing. |
| QINJ | 1–2 pC - reduces settling error in high-impedance sample-and-hold circuits. |
| ICOM(on) | ≤ 200 pA max - preserves accuracy in µA-level sensor signal conditioning. |
| OIRR | −74 dB at 1 MHz - ensures strong isolation between NC/NO paths in RF-adjacent analog routing. |
| ESD Rating | >2000 V HBM - enhances reliability in handheld and field-deployable equipment handling. |
Pinout & Package
Package: 8-pin narrow-body SOIC (SOIC-8), 150 mil width, RoHS-compliant Pb-free terminations (E3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Digital control input | Active-high logic: IN = 0 V → NC closed; IN = V+ → NO closed. |
| 2 (NO) | Normally open switch terminal | Connects to COM only when IN is high; bidirectional analog path. |
| 3 (NC) | Normally closed switch terminal | Connects to COM only when IN is low; bidirectional analog path. |
| 4 (GND) | Analog/digital ground reference | Common return for power, logic, and signal paths; must be low-impedance. |
| 5 (COM) | Common analog terminal | Shared I/O node; routes signal to either NO or NC based on IN state. |
| 6 (V+) | Positive supply rail | Powers internal logic and switch core; also defines analog signal swing limit (0 to V+). |
| 7, 8 | No connect (NC) | Internally unconnected; left floating or tied to GND per layout best practice. |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make guarantee | Eliminates momentary shorting between NC and NO paths during switching - essential for fault-tolerant analog multiplexing. |
| Low charge injection (1–2 pC) | Minimizes voltage glitch on hold capacitors, enabling sub-12-bit accuracy in sample-and-hold stages. |
| Bidirectional conduction | Supports signal routing in either direction without polarity constraints - simplifies PCB layout in AC-coupled paths. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESA+ | rDS(on) = 35 Ω (typ) at +5 V; tON = 45 ns; no guaranteed break-before-make | Lacks BbM guarantee; higher leakage (ICOM(on) = 500 pA max) | Acceptable where BbM is not safety-critical and slightly higher on-resistance is tolerable. |
| ADG774ARZ | rDS(on) = 2.5 Ω (typ) at +5 V; tON = 12 ns; requires dual supply (±2.5 V) or single +5 V with level shifters | Lower rDS(on) but incompatible logic interface without external circuitry | Preferred for ultra-low-loss paths if supply architecture allows; not drop-in compatible with DG9461DY-T1-E3. |
Compared with MAX4617ESA+ and ADG774ARZ, the DG9461DY-T1-E3 offers guaranteed break-before-make timing and single-supply simplicity at moderate on-resistance - making it optimal for cost-sensitive, space-constrained portable systems where signal integrity and layout efficiency are prioritized over ultra-low rDS(on).

FAQ
What is the maximum analog signal voltage range supported by the DG9461DY-T1-E3?
The DG9461DY-T1-E3 supports analog signals from 0 V to V+, where V+ ranges from +2.7 V to +12 V. At V+ = 5 V, the full analog range is 0 V to 5 V. Signals exceeding V+ or going below GND are clamped by internal diodes - forward current must be limited to avoid damage. This rail-to-rail capability makes DG9461DY-T1-E3 suitable for unipolar signal routing in mixed-signal systems without external level shifting.
Does the DG9461DY-T1-E3 require external pull-up or pull-down resistors on the IN pin?
No, the DG9461DY-T1-E3 does not require external pull-up or pull-down resistors on the IN pin. Its TTL/CMOS-compatible input accepts logic low ≤ 0.8 V and logic high ≥ 2.4 V across the full supply range. Input current is ≤ 1 µA, so standard microcontroller GPIO outputs drive it directly. External resistors are unnecessary unless system-level noise immunity or power-down state retention is required - which is outside DG9461DY-T1-E3's specified behavior.
Is break-before-make timing guaranteed for the DG9461DY-T1-E3 across temperature and voltage?
Yes, break-before-make timing is guaranteed for the DG9461DY-T1-E3 across its full operating range of −40 °C to +85 °C and V+ = +2.7 V to +12 V. The datasheet explicitly states "Break-before-make is guaranteed for DG9461" - confirmed in both functional description and truth table. Measured td (break interval) is 3–20 ns at room temperature, with no degradation reported over voltage or temperature extremes in characterization data.
Can the DG9461DY-T1-E3 be used with bipolar analog signals?
No, the DG9461DY-T1-E3 is not rated for true bipolar analog signals (e.g., ±2.5 V). It is a single-supply device with analog terminals (COM, NO, NC) restricted to 0 V to V+. Applying negative voltages risks forward-biasing internal ESD diodes and exceeding absolute maximum ratings. For bipolar operation, a dual-supply switch like the ADG774ARZ or dedicated level-shifting circuitry is required - DG9461DY-T1-E3 must be used in unipolar configurations only.
What is the thermal resistance (θJA) of the DG9461DY-T1-E3 in SOIC-8 package?
The DG9461DY-T1-E3 in SOIC-8 package has a maximum power dissipation of 400 mW at +75 °C, with derating of 6.5 mW/°C above that temperature. While θJA is not explicitly listed in the datasheet, the 400 mW rating at +75 °C implies a typical θJA ≈ 154 °C/W (calculated from (125 − 75) °C / 0.4 W). Layout-dependent factors such as copper area and airflow significantly affect actual thermal performance - refer to Vishay's package reliability documents (PPG?70832) for recommended land patterns and thermal vias.
