Product details
Overview
DG384AAK/883 from Vishay Siliconix is a hermetically sealed, military-grade dual SPDT CMOS analog switch in 16-pin CerDIP package, rated for –55 °C to +125 °C operation. It features 30 Ω typical rDS(on), ±15 V dual-supply or single-supply (0 V to +15 V) operation, break-before-make switching, and full rail-to-rail analog signal handling - used in precision instrumentation signal routing and MIL-STD-883 qualified test equipment.
For engineers reviewing the DG384AAK/883 datasheet, DG384AAK/883 pinout, DG384AAK/883 application, or DG384AAK/883 equivalent, key selection criteria include guaranteed break-before-make timing, low charge injection (10 pC), leakage <100 nA at 125 °C, and compatibility with JFET DG180-family layouts in high-reliability analog front-ends.
Technical Context
The DG384AAK/883 implements two independent SPDT analog switches fabricated on Vishay's PLUS-40 CMOS process, enabling 3.5 mW typical power dissipation and latchup immunity via epitaxial isolation. Each switch supports bidirectional conduction with symmetrical on-resistance and rail-to-rail analog voltage swing from V– to V+.
Logic inputs are quasi-TTL compatible (0.8 V low / 4 V high thresholds), and break-before-make timing is guaranteed across temperature and supply voltage. Internal clamping diodes protect S/D terminals against overvoltage transients up to (V–) –2 V or (V+) +2 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| rDS(on) | 30 Ω typical - ensures minimal signal attenuation and distortion in precision analog paths |
| Analog Signal Range | Full rail-to-rail (–15 V to +15 V) - supports unipolar and bipolar signal routing without clipping |
| Turn-On/Off Time | 150/130 ns typical - enables fast multiplexing in data acquisition and ATE systems |
| Charge Injection | 10 pC - reduces settling error in sample-and-hold and integrator circuits |
| Off-Leakage Current | <100 nA at 125 °C - maintains signal integrity in high-impedance sensor interfaces |
| Supply Voltage Range | V+ = 44 V max, V– = –2 V min - allows flexible biasing in wide-dynamic-range systems |
| Power Dissipation | 825 mW (16-pin CerDIP) - supports continuous operation in sealed enclosures with derating above 75 °C |
Pinout & Package
Package: 16-pin ceramic dual-in-line package (CerDIP), hermetically sealed, MIL-STD-883 qualified, lead finish per specification 5962-9678801QEA.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16 | NC | No connect - unused internal node; must be left floating or tied to GND per layout guidelines |
| 2, 15 | S1, S2 | Switch source terminals - bidirectional analog inputs/outputs for SPDT channels |
| 3, 14 | D1, D2 | Switch drain terminals - common analog outputs/inputs routed by control logic |
| 4, 13 | IN1, IN2 | Digital control inputs - TTL-compatible logic signals enabling respective SPDT switch |
| 5, 12 | V–, V+ | Negative/positive supply rails - define analog signal range and power domain |
| 6, 11 | GND, NC | Ground reference and no-connect - GND provides logic reference; NC must not be bonded |
| 7–10 | S3, D3, S4, D4 | Unused channel terminals - not connected internally; must remain unconnected |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed tOPEN ≥ 50 ns - prevents momentary short-circuit during channel switching |
| Rail-to-rail analog signal handling | VANALOG = V– to V+ - eliminates level-shifting circuitry in ±15 V systems |
| Low charge injection (10 pC) | Minimizes voltage glitch in sample-and-hold and integrator applications |
| Hermetic CerDIP packaging | MIL-STD-883 Class B screening - ensures reliability in aerospace, defense, and downhole environments |
| PLUS-40 CMOS process | Eliminates latchup and enables 3.5 mW typical power - critical for battery-backed instrumentation |

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 |
|---|---|---|---|
| DG381BK/883 | Pin-for-pin replacement with 25 Ω rDS(on), lower 5 pC charge injection, same CerDIP package and MIL-STD-883 screening | Better performance in ultra-low-distortion integrators and precision DAC output switching | Select when lower on-resistance and reduced charge injection are required without layout change |
| ADG1414KPZ-REEL | 16-pin TSSOP, 1.5 Ω rDS(on), but non-hermetic, commercial temp range only (–40 °C to +125 °C), no MIL-STD-883 qualification | Suitable for industrial automation where hermeticity and extended cold start not required | Choose for cost-sensitive, space-constrained designs where military reliability is not mandated |
Compared with DG384AAK/883, DG381BK/883 offers improved analog fidelity in high-precision signal paths, while ADG1414KPZ-REEL provides superior on-resistance in commercial-grade compact layouts - neither is drop-in compatible without requalification due to differing screening, packaging, or electrical envelope.

FAQ
What is the maximum analog signal voltage range supported by DG384AAK/883?
The DG384AAK/883 supports a full rail-to-rail analog signal range from V– to V+, with absolute maximum ratings of V+ ≤ +44 V and V– ≥ –2 V relative to ground. Under standard ±15 V dual-supply operation, this delivers –15 V to +15 V analog swing - confirmed in the datasheet's Analog Signal Range parameter (VANALOG) and Figure 1 schematic.
Does DG384AAK/883 require dual supplies, or can it operate from a single supply?
DG384AAK/883 supports both dual-supply (e.g., V+ = +15 V, V– = –15 V) and single-supply operation (V– tied to 0 V, V+ = +5 V to +15 V). Single-supply use is explicitly validated in the datasheet's "Single Supply Operation" section and Figure 8, though with trade-offs in rDS(on) and switching speed.
Is DG384AAK/883 pin-compatible with the DG180 JFET switch family?
Yes - the DG384AAK/883 is pin and function compatible with the JFET DG180 family, as stated in the datasheet's Key Features section. This enables direct replacement in legacy designs without PCB modification, preserving existing layout and footprint while upgrading to CMOS performance and latchup immunity.
What is the guaranteed break-before-make timing for DG384AAK/883?
The DG384AAK/883 guarantees break-before-make timing (tOPEN) of ≥50 ns under all operating conditions, as specified in the Dynamic Characteristics table on page 4 of the datasheet. This parameter is production-tested and ensures no overlap between switch closure events in either SPDT channel.
How is DG384AAK/883 screened and qualified for military applications?
DG384AAK/883 is manufactured to MIL-STD-883 requirements and carries the 5962-9678801QEA device type designation. It undergoes Class B screening including temperature cycling, hermeticity testing, and burn-in - documented in the Vishay datasheet revision A and applicable military specification annexes.
