Product details
Overview
DG301AAA/883 from Vishay Siliconix is a hermetically sealed, 10-pin metal-can SPDT analog switch designed for precision signal routing in military-grade instrumentation and process control systems. It supports ±15 V analog signal range, exhibits 30 Ω typical on-resistance, 150 ns turn-on time, and operates across –55 °C to +125 °C with dual-supply (±15 V) or single-supply (0 V to +15 V) configurations.
For engineers reviewing the DG301AAA/883 datasheet, DG301AAA/883 pinout, DG301AAA/883 application, or DG301AAA/883 equivalent, key selection criteria include break-before-make timing (50 ns), rail-to-rail analog conduction, latch-up immunity, low charge injection (8 pC), and MIL-PRF-38535 Class B qualification with 883 screening.
Technical Context
The DG301AAA/883 implements a CMOS-based SPDT switch architecture with epitaxial isolation to prevent latch-up, enabling robust operation up to ±30 V peak-to-peak off-state blocking. Its digital inputs are compatible with TTL and CMOS logic levels (0.8 V low / 4 V high), and it features true bidirectional analog conduction with no offset voltage in the on state.
Designed on the Vishay PLUS-40 CMOS process, the device delivers stable rDS(on) over temperature and supply voltage, supports break-before-make switching to avoid transient shorts, and maintains low leakage (<100 nA at 125 °C) under full-rated analog conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V - Supports full rail-to-rail signal switching without clipping when V+ = +15 V, V− = −15 V. |
| rDS(on) (Typ) | 30 Ω - Enables low insertion loss and minimal signal distortion in precision gain-setting and multiplexing paths. |
| tON/tOFF | 150 ns / 130 ns - Allows high-speed channel selection in data acquisition and real-time control loops. |
| Break-Before-Make Time | 50 ns - Guarantees no momentary short between S1 and S2 during state transition, critical for fault-tolerant signal routing. |
| Charge Injection | 8 pC - Minimizes voltage glitch on high-impedance nodes (e.g., sample-and-hold inputs), preserving measurement accuracy. |
| Off-Leakage (Hot) | 100 nA at 125 °C - Ensures stable DC bias integrity in long-duration sensor conditioning circuits. |
| Supply Current (I+, I−) | 0.23 mA / −10 µA - Supports ultra-low-power operation in battery-backed or energy-constrained embedded subsystems. |
Pinout & Package
Package: 10-pin metal can (hermetic), case-connected to V+ (substrate and case), suitable for high-reliability aerospace and defense applications requiring moisture and particle resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9, 10 | NC | No internal connection - electrically isolated; must be left unconnected or tied to V+ per layout guidelines. |
| 2 | S2 | SPDT switch output terminal 2 - connects to D2 when IN2 = logic high; bidirectional analog path. |
| 3 | V− | Negative supply rail - referenced to system ground; sets lower bound of analog signal range. |
| 4 | D2 | SPDT switch input terminal 2 - common analog node routed to S2 or S1 depending on control state. |
| 5 | D1 | SPDT switch input terminal 1 - common analog node routed to S1 or S2 depending on control state. |
| 6 | V+ | Positive supply rail and substrate/case connection - defines upper analog rail; case must be grounded via V+. |
| 7 | S1 | SPDT switch output terminal 1 - connects to D1 when IN1 = logic high; bidirectional analog path. |
| 8 | IN1 | Digital control input for S1/D1 path - active-high TTL/CMOS compatible (min 4 V for ON). |
| 10 | GND | Logic ground reference - separate from analog ground; required for proper input threshold referencing. |
Key Features
| Feature | Design Value |
|---|---|
| Latch-up proof construction | Epitaxial layer prevents parasitic SCR activation - ensures reliable operation under overvoltage transients in harsh environments. |
| Rail-to-rail analog conduction | Switches signals from V− to V+ with no dead zone - eliminates clipping in ±15 V instrumentation amplifier front-ends. |
| Break-before-make timing | Guaranteed 50 ns minimum gap between S1 and S2 conduction - prevents signal shorting during gain or channel reconfiguration. |
| Low charge injection (8 pC) | Reduces settling error in sample-and-hold and switched-capacitor circuits - critical for 12-bit+ ADC driver stages. |
| MIL-PRF-38535 Class B qualified | Meets stringent screening, testing, and traceability requirements for spaceflight and tactical systems - includes 883-level burn-in and parametric verification. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DG301AAK/883 | 14-pin cerdip package; identical electrical specs and MIL-883 screening; higher power dissipation rating (825 mW vs. 450 mW). | Preferred where PCB layout allows larger footprint and higher thermal margin; not pin-compatible due to different pin count and arrangement. | Select DG301AAK/883 when board space permits and higher power handling is needed; DG301AAA/883 remains optimal for compact, hermetic, metal-can deployments. |
| DG300AAA/883 | SPST configuration (single pole); same 10-pin metal-can package, temperature range, and screening level; shares rDS(on), leakage, and timing specs. | Used where only one switch path is required per IC; lacks second switch leg and associated control pin (IN2). | Choose DG300AAA/883 for simpler, lower-pin-count SPST routing; DG301AAA/883 is required for dual-path (S1/S2) selection from a common D1/D2 node. |
Compared with DG301AAK/883 and DG300AAA/883, the DG301AAA/883 uniquely combines SPDT functionality, 10-pin metal-can hermeticity, and 450 mW power dissipation - making it the only option for space-constrained, high-reliability dual-path analog routing requiring MIL-883 compliance.

FAQ
What is the maximum analog signal voltage range supported by the DG301AAA/883?
The DG301AAA/883 supports a full rail-to-rail analog signal range of ±15 V when operated with dual supplies (V+ = +15 V, V− = −15 V). This allows undistorted switching of signals spanning the entire supply rails, essential for precision instrumentation amplifier interfaces and sensor signal conditioning circuits where headroom and linearity are critical. The DG301AAA/883 guarantees this range by design and is tested to block up to ±30 V peak-to-peak in the off state.
Does the DG301AAA/883 require both positive and negative supplies to operate?
No - the DG301AAA/883 supports both dual-supply (±15 V) and single-supply (0 V to +15 V) operation. In single-supply mode, V− is connected to ground, and the analog range becomes 0 V to +15 V. However, rDS(on) increases and switching speed decreases slightly compared to dual-supply operation. The DG301AAA/883 maintains CMOS/TTL compatibility and latch-up immunity in either configuration, making it adaptable to legacy and modern power architectures.
What does the "/883" suffix indicate for the DG301AAA/883 part number?
The "/883" suffix denotes full compliance with MIL-STD-883 test methods and screening requirements, including temperature cycling, burn-in, and parametric verification per MIL-PRF-38535 Class B. This ensures the DG301AAA/883 meets the reliability, traceability, and environmental robustness standards required for aerospace, defense, and high-integrity industrial applications. The DG301AAA/883 is manufactured and tested to these specifications, with full lot traceability and documentation.
How is the metal-can case of the DG301AAA/883 electrically connected, and why does it matter?
The metal-can case of the DG301AAA/883 is internally bonded to the V+ terminal (substrate and case), as explicitly stated in the top-view diagram. This connection serves two purposes: it provides EMI shielding for sensitive analog paths and establishes a low-inductance thermal and electrical path for the positive supply rail. Proper mechanical mounting - such as soldering the can to a V+-poured copper plane - is essential to maintain signal integrity and thermal performance in high-frequency or high-reliability designs using the DG301AAA/883.
Is the DG301AAA/883 pin-compatible with any newer Vishay replacement series?
No - the DG301AAA/883 is part of the obsolete DG300A_MIL family. Vishay recommends the DG300B series as pin-for-pin replacements for non-hermetic versions, but no direct metal-can, MIL-883–screened successor exists. The DG301AAA/883 remains the only available hermetic, 10-pin SPDT switch with its exact form, fit, and function. For new designs requiring modern process benefits, engineers must evaluate redesign feasibility or confirm continued long-term availability of the DG301AAA/883 through Aetrix Electronics' lifecycle management program.
