Product details
Overview
DG306AAK/883 from Vishay Siliconix is a dual SPST analog switch IC designed for precision signal routing in high-reliability military and aerospace systems. It features 15-V input range, 30 Ω typical rDS(on), 110 ns turn-on time, and operates across –55°C to +125°C. It enables rail-to-rail analog switching in programmable gain amplifiers and low-power instrumentation front-ends.
For engineers reviewing the DG306AAK/883 datasheet, DG306AAK/883 pinout, DG306AAK/883 application, or DG306AAK/883 equivalent, this page delivers verified specifications, CerDIP-14 package details, break-before-make timing behavior, leakage performance at extended temperature, and direct alternatives for MIL-PRF-38535 Class B qualified designs.
Technical Context
The DG306AAK/883 implements two independent CMOS SPST switches fabricated on Vishay's PLUS-40 process, ensuring micropower operation (30 nW) without sacrificing speed. Each switch supports bidirectional conduction with guaranteed break-before-make action and latchup immunity via epitaxial isolation.
It requires dual ±15 V supplies (V+ = +15 V, V– = –15 V), accepts CMOS logic inputs (VIH = 11 V, VIL = 3.5 V), and maintains full rail-to-rail analog signal range (–15 V to +15 V) with low charge injection (30 pC) and high off-isolation (62 dB).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | –15 V to +15 V - supports full swing signals across entire supply rails without clipping |
| rDS(on) | 30 Ω typ - ensures minimal voltage drop and signal attenuation in precision analog paths |
| tON/tOFF | 110 ns / 70 ns - enables fast multiplexing in data acquisition and real-time control loops |
| IS(off)/ID(off) | ±100 nA max - guarantees low error in high-impedance sensor interfaces and integrator circuits |
| Charge Injection | 30 pC - minimizes settling error in sample-and-hold and switched-capacitor applications |
| Off-Isolation (OIRR) | 62 dB - suppresses crosstalk between channels in multi-signal routing systems |
| Operating Temp | –55°C to +125°C - qualified per MIL-PRF-38535 Class B for space and avionics use |
Pinout & Package
Package: 14-Pin Ceramic Dual-In-Line (CerDIP), hermetically sealed, lead finish per MIL-STD-1835, compliant with Class B screening requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 6, 11, 12 | No Connect (NC) | Internally unconnected; must remain floating or tied to GND per layout guidelines |
| 2 | V+ | Positive supply rail (+15 V typical); also substrate/case connection in metal-can variants |
| 3, 4 | D1, D2 | Drain terminals of SPST switches; bidirectional analog signal outputs |
| 7 | S1 | Source terminal of Switch 1; connects to analog signal path when IN1 = logic high |
| 8 | S2 | Source terminal of Switch 2; connects to analog signal path when IN2 = logic high |
| 9, 10 | IN2, IN1 | Digital control inputs; active-high CMOS-compatible (VIH = 11 V min, VIL = 3.5 V max) |
| 13 | GND | Analog/digital reference ground; separate from V– but referenced to same potential |
| 14 | V– | Negative supply rail (–15 V typical); required for rail-to-rail analog operation |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JM38510/11607BCA | 10-pin metal can package; identical electrical specs and Class B qualification | Requires different PCB footprint and thermal management due to can geometry and lead form | Select when legacy metal-can mechanical interface or specific thermal profile is mandated |
| DG306ACJ | Same die, but 14-pin CerDIP with commercial temp range (–25°C to +85°C) and no MIL screening | Not suitable for extended temperature or radiation-hardened deployments | Select only for non-military industrial prototypes where cost and availability outweigh qualification needs |
Compared with DG306AAK/883, JM38510/11607BCA offers identical performance in a legacy metal-can form factor but demands mechanical redesign, while DG306ACJ provides cost savings only in non-qualified environments-neither is pin-compatible nor drop-in replaceable without validation.

FAQ
What is the maximum analog signal voltage supported by the DG306AAK/883?
The DG306AAK/883 supports a full rail-to-rail analog signal range from –15 V to +15 V when operated with ±15 V supplies. This is guaranteed by design and enables direct interfacing with bipolar sensor outputs and op-amp stages without external level shifting. The DG306AAK/883 maintains low distortion and consistent rDS(on) across this entire range.
Does the DG306AAK/883 require dual supplies, or can it operate from a single supply?
The DG306AAK/883 requires dual supplies (V+ and V–) to achieve its specified rail-to-rail analog performance and guaranteed break-before-make timing. While the datasheet notes single-supply operation is possible for positive-only voltages (by tying V– to 0 V), that configuration degrades analog range, increases rDS(on), and voids MIL-PRF-38535 qualification. The DG306AAK/883 is intended for dual-supply use in high-fidelity applications.
What is the meaning of the "/883" suffix in DG306AAK/883?
The "/883" suffix indicates compliance with MIL-STD-883, Test Method Standard for Microcircuits, including screening tests such as burn-in, temperature cycling, and parametric verification per MIL-PRF-38535 Class B. This makes the DG306AAK/883 suitable for high-reliability defense and space programs. The DG306AAK/883 is not a commercial-grade part and carries full military traceability and documentation.
How does the DG306AAK/883 handle digital input voltage levels?
The DG306AAK/883 accepts standard CMOS logic inputs: VIH (minimum high-level input) is 11 V, and VIL (maximum low-level input) is 3.5 V, referenced to V–. Inputs exceeding V+ or V– are clamped by internal diodes, so external current limiting is required if signals exceed supply rails. The DG306AAK/883 ensures reliable switching across its full operating temperature range without logic threshold drift.
Is the DG306AAK/883 pin-compatible with other devices in the DG304A–DG307A family?
The DG306AAK/883 shares the same 14-pin CerDIP pinout with DG304A, DG305A, and DG307A variants, but functional differences exist: DG304A is quad SPST, DG305A/DG307A are SPDT with break-before-make, and DG306A is dual SPST. While physical pin alignment matches, substituting DG306AAK/883 for another variant requires verifying logic mapping, channel count, and timing behavior-no drop-in replacement is assured without circuit validation.
