Product details
Overview
DG302AAK/883 from Vishay Siliconix is a hermetically sealed, military-grade dual SPDT CMOS analog switch in a 14-pin ceramic DIP package, rated for -55 °C to +125 °C operation. It supports ±15 V analog signal range, exhibits 30 Ω typical on-resistance, 150 ns turn-on time, and break-before-make switching-designed for precision signal routing in aerospace instrumentation and hardened test equipment.
For engineers reviewing the DG302AAK/883 datasheet, DG302AAK/883 pinout, DG302AAK/883 application, or DG302AAK/883 equivalent, key selection criteria include rail-to-rail analog handling, latch-up immunity, low charge injection (8 pC), guaranteed off-isolation (>62 dB), and compatibility with TTL/CMOS logic levels across full temperature range.
Technical Context
The DG302AAK/883 implements two independent SPDT switches using Vishay's PLUS-40 CMOS process with epitaxial isolation to prevent latch-up. Each channel conducts bidirectionally with no offset voltage and blocks up to ±30 V peak-to-peak when off.
It operates from dual supplies (±15 V typical) or single supply (V− = 0 V), with logic thresholds fixed at 0.8 V (low) and 4 V (high). Switching is break-before-make only in DG301A_MIL; DG302AAK/883 supports independent control of both SPDT sections without interlock.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V - supports full rail-to-rail signal switching without clipping |
| Drain-Source On-Resistance | 30 Ω typ - minimizes signal attenuation and gain error in precision paths |
| Turn-On Time | 150 ns - enables high-speed multiplexing in data acquisition systems |
| Off-Isolation | 62 dB - suppresses crosstalk between active and inactive channels |
| Charge Injection | 8 pC - reduces settling error in sample-and-hold and ADC front-end circuits |
| Supply Current | 0.23 mA typ - enables low-power operation in battery-backed or remote systems |
| Operating Temperature | -55 °C to +125 °C - qualified per MIL-PRF-38535 Class B for space and defense use |
Pinout & Package
Package: 14-pin ceramic dual-in-line (CerDIP), hermetically sealed, compliant with MIL-STD-883.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 14 | V+ | Positive supply rail; must be ≥ |V−| for symmetric operation |
| 2, 13 | S3 / S4 | SPDT switch 2 source terminals - bidirectional analog inputs |

| 4, 11 | D1 / D2 | SPDT switch 1 drain terminals - primary output nodes |
| 5, 10 | S1 / S2 | SPDT switch 1 source terminals - primary analog inputs |
| 6, 9 | IN1 / IN2 | CMOS/TTL-compatible digital control inputs for each SPDT section |
| 7 | GND | Digital ground reference; tied to substrate in metal-can variants but isolated in CerDIP |
| 8 | V− | Negative supply rail; required for bipolar analog range and leakage control |
Key Features
| Feature | Design Value |
|---|---|
| Latch-up proof construction | Epitaxial isolation prevents destructive latch-up under overvoltage or ESD stress |
| Rail-to-rail analog conduction | Switches pass signals from V− to V+ with no dead zone or distortion |
| Low power dissipation | 3.5 mW typical - extends battery life and reduces thermal load in dense layouts |
| Break-before-make not enforced | Independent control allows simultaneous switching or custom timing sequences |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRUZ | Single-supply only (up to 33 V), 3.5 Ω rDS(on), no V− pin | Not suitable for bipolar analog signals or MIL-temperature operation | Select only for commercial, single-rail systems requiring ultra-low on-resistance |
| HI-506ACDWZ | 16-pin SOIC, ±15 V rating, 120 Ω rDS(on), non-hermetic | Lacks MIL-PRF-38535 qualification and hermetic sealing | Acceptable for industrial-grade instrumentation where cost and footprint constrain design |
Compared with DG302AAK/883, ADG1419BRUZ offers lower on-resistance but cannot handle bipolar analog signals or extreme temperatures; HI-506ACDWZ provides similar voltage range and dual SPDT function but lacks hermeticity and military qualification-making DG302AAK/883 the sole choice for mission-critical aerospace and defense deployments.

FAQ
What is the maximum analog signal voltage supported by DG302AAK/883?
DG302AAK/883 supports a full rail-to-rail analog signal range of ±15 V when operated with dual supplies. The absolute maximum analog voltage is ±30 V peak-to-peak, but sustained operation beyond ±15 V requires verification of signal integrity and leakage in the target application. DG302AAK/883 is not rated for continuous 30 V swing under all conditions.
Does DG302AAK/883 require both positive and negative supplies to operate?
DG302AAK/883 can operate from dual supplies (e.g., V+ = +15 V, V− = −15 V) for full bipolar analog range, or from a single supply (V− = 0 V) for unipolar signals up to +15 V. However, single-supply operation increases rDS(on) and slows switching speed, and is not recommended for precision applications per the datasheet application hints. DG302AAK/883 functions correctly only when V+ and V− are within absolute maximum ratings.
Is DG302AAK/883 pin-compatible with DG301AAK/883 or DG300AAK/883?
No, DG302AAK/883 is not pin-compatible with DG301AAK/883 or DG300AAK/883. While all three share the same 14-pin CerDIP package outline, their internal switch configurations differ: DG300A_MIL is SPST ×4, DG301A_MIL is SPDT ×2 with break-before-make, and DG302AAK/883 is SPDT ×2 with independent control. Pin assignments for S/D/IN terminals are distinct across the family, as confirmed in the functional block diagrams and truth tables.
What is the logic voltage threshold for DG302AAK/883 digital inputs?
DG302AAK/883 digital inputs accept standard CMOS/TTL logic levels: logic low is defined as ≤0.8 V, and logic high as ≥4 V, regardless of supply voltage. These thresholds remain stable across the full −55 °C to +125 °C operating range and are not dependent on V+ or V− magnitude. DG302AAK/883 does not support 3.3 V logic directly without level translation.
Can DG302AAK/883 be used in spaceflight applications?
Yes, DG302AAK/883 is qualified per MIL-PRF-38535 Class B and tested to MIL-STD-883 methods, including radiation hardness assurance (RHA) screening per Method 1019. Its hermetic ceramic DIP package, latch-up immunity, and guaranteed parametric performance across −55 °C to +125 °C make it suitable for low-earth orbit (LEO) spacecraft telemetry and payload interface systems-provided total ionizing dose (TID) and single-event effect (SEE) requirements align with its certified limits.
