Product details
Overview
DG300AAA/883 from Vishay Siliconix is a hermetically sealed, 10-pin metal-can SPST 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 DG300AAA/883 datasheet, DG300AAA/883 pinout, DG300AAA/883 application, or DG300AAA/883 equivalent, this page delivers verified pin mapping, rail-to-rail switching behavior, latch-up immunity, break-before-make timing, and MIL-PRF-38535 Class B qualification - all critical for high-reliability analog multiplexing and programmable gain amplifier design.
Technical Context
The DG300AAA/883 implements a CMOS transmission gate architecture fabricated on Vishay's PLUS-40 process, featuring an epitaxial layer that prevents latch-up under transient overvoltage conditions. Its control logic accepts TTL- and CMOS-compatible inputs (0.8 V low / 4 V high), enabling direct interface with legacy digital controllers without level-shifting.
In the on-state, it conducts bidirectionally with zero offset voltage and minimal signal distortion; in the off-state, it blocks up to ±30 V peak-to-peak analog signals while maintaining sub-100 nA leakage at 125 °C - essential for low-error data acquisition in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V - supports full rail-to-rail signal switching without clipping in dual-supply mode. |
| Drain-Source On-Resistance | 30 Ω typ - ensures <0.1% gain error in 10 kΩ impedance paths at mid-scale analog voltages. |
| Turn-On Time | 150 ns - enables sampling rates up to ~3 MHz in time-critical multiplexer applications. |
| Off-Leakage Current | ±100 nA max at 125 °C - preserves accuracy in high-impedance sensor front-ends and integrator circuits. |
| Supply Voltage Range | V+ = +15 V, V− = −15 V - compatible with standard bipolar op-amp rails and legacy test equipment supplies. |
| Operating Temperature | −55 °C to +125 °C - qualified per MIL-PRF-38535 Class B for aerospace and defense deployments. |
| Power Dissipation | 450 mW max (derated 6 mW/°C above 75 °C) - defines thermal limits for continuous operation in sealed enclosures. |
Pinout & Package
Package: 10-pin metal can (hermetic), case connected to V+ (substrate and case tie).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN2 | Second digital control input - enables independent switching of second channel in dual-channel variants (not used in DG300AAA/883 SPST configuration). |
| 2 | S2 | Second source terminal - unused in DG300AAA/883; left unconnected per functional block diagram. |
| 3 | V− | Negative supply rail - must be tied to −15 V (or 0 V in single-supply mode); serves as reference for analog and digital domains. |
| 4 | D2 | Second drain terminal - not bonded or functional in DG300AAA/883 SPST topology. |
| 5 | D1 | Analog drain (output) - connects to load or downstream circuit; bidirectional conduction when switch is on. |
| 6 | V+ | Positive supply rail and case connection - ties substrate to V+, providing EMI shielding and stable reference for internal CMOS gates. |
| 7 | S1 | Analog source (input) - accepts rail-to-rail analog signals up to ±15 V; symmetric conduction path with D1. |
| 8 | IN1 | Digital control input - TTL/CMOS-compatible; 0.8 V low / 4 V high threshold enables direct microcontroller interfacing. |
| 9 | GND | Logic ground reference - isolated from analog ground in mixed-signal layouts to minimize noise coupling. |
| 10 | NC | No connect - internally unconnected; must remain floating per datasheet pin configuration diagrams. |
Key Features
| Feature | Design Value |
|---|---|
| Latch-up proof construction | Epitaxial layer prevents destructive latch-up even under 30 V transient overvoltage events. |
| Rail-to-rail analog switching | Supports ±15 V signal swing with no degradation in rDS(on) or leakage - eliminates need for external clamping diodes. |
| Low charge injection (8 pC) | Minimizes voltage glitch on high-impedance nodes during switching - critical for sample-and-hold and ADC front-end stability. |
| Break-before-make timing | Guaranteed tOPEN ≥ 50 ns in DG301A_MIL variant; DG300AAA/883 SPST avoids short-through during state transitions. |
| Hermetic metal-can packaging | Meets MIL-PRF-38535 Class B requirements for moisture resistance, thermal cycling, and long-term reliability in space-constrained avionics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DG300AAK/883 | 14-pin cerdip package; identical electrical specs and temperature range; higher thermal resistance (825 mW vs. 450 mW). | Preferred where PCB layout allows larger footprint and higher power dissipation is needed. | Select DG300AAK/883 for ease of hand-soldering or when thermal margin exceeds 450 mW requirement. |
| DG300B Series (e.g., DG300BDY) | Non-hermetic SOIC-14; pin-for-pin compatible but not MIL-qualified; rDS(on) = 25 Ω typ; tON = 125 ns. | Intended for commercial/industrial use only; lacks hermetic sealing and extended temperature certification. | Choose DG300B only for cost-sensitive, non-military applications where hermeticity and Class B qualification are unnecessary. |
Compared with DG300AAK/883, DG300AAA/883 offers superior thermal performance in confined spaces due to lower thermal resistance and metal-can EMI shielding; compared with DG300B, it provides guaranteed MIL-PRF-38535 reliability and radiation tolerance at the expense of package size and cost.

FAQ
What is the maximum analog signal voltage supported by DG300AAA/883?
DG300AAA/883 supports a full rail-to-rail analog signal range of ±15 V when operated with dual supplies (V+ = +15 V, V− = −15 V). The device blocks up to ±30 V peak-to-peak in the off-state. Exceeding these limits risks permanent damage due to internal clamp diode conduction or breakdown.
Does DG300AAA/883 require separate analog and digital ground planes?
Yes - DG300AAA/883 has dedicated GND (pin 9) for logic reference and V− (pin 3) for analog return. Best practice is to isolate analog and digital grounds at a single point near the device, minimizing noise coupling into sensitive analog paths while maintaining clean logic thresholds.
Is DG300AAA/883 pin-compatible with DG300B-series replacements?
No - DG300AAA/883 uses a 10-pin metal-can package with unique pinout (including V+ tied to case), whereas DG300B-series devices use 14-pin SOIC packages with different pin assignments and no case tie. They are functionally similar but not mechanically or electrically interchangeable without PCB redesign.
What is the purpose of connecting V+ to the metal case in DG300AAA/883?
The V+ (pin 6) connection to the metal case in DG300AAA/883 provides electrostatic shielding, reduces EMI susceptibility, and stabilizes the substrate potential - critical for maintaining latch-up immunity and low crosstalk (<74 dB) in high-density analog signal routing applications.
Can DG300AAA/883 operate from a single +15 V supply?
Yes - DG300AAA/883 supports single-supply operation by tying V− (pin 3) to 0 V. However, this increases rDS(on) and slows switching speed versus dual-supply mode. Analog input range becomes 0 V to +15 V, and input logic thresholds shift accordingly (VINH min = 4 V, VINL max = 0.8 V).
