Product details
Overview
DG186AA/883 from Vishay Siliconix is a radiation-hardened, precision SPDT analog switch built with n-channel JFETs and TTL-compatible bipolar driver circuitry. It delivers 10 Ω typical on-resistance (rDS(on)), <2 nA channel-on leakage (ID(on)), and break-before-make switching for audio/video signal routing in harsh environments. Used in telemetry systems and guidance control where signal integrity and radiation tolerance are critical.
For engineers reviewing the DG186AA/883 datasheet, DG186AA/883 pinout, DG186AA/883 application, or DG186AA/883 equivalent, this page provides verified electrical specs, military-grade package details, switching timing data, analog signal range limits, and validated alternative options for high-reliability analog switching design.
Technical Context
The DG186AA/883 implements dual n-channel JFET switches controlled by an integrated TTL-compatible driver that enforces break-before-make operation to prevent channel shorting and crosstalk. Its analog signal path supports bidirectional conduction with flat on-resistance across –7.5 V to +15 V range.
It requires four independent supply rails: V+ (+15 V), V– (–15 V), VL (+5 V logic), and VR (ground reference). Input logic thresholds are VINH ≥ 2.0 V and VINL ≤ 0.8 V, ensuring compatibility with standard TTL levels under full military temperature range (–55 °C to +125 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | –7.5 V to +15 V - supports rail-to-rail video/audio signals without clipping in dual-supply systems. |
| Drain-Source On-Resistance | 10 Ω max - ensures minimal insertion loss and distortion in precision analog paths. |
| Channel-On Leakage Current | <2 nA at 7.5 V - preserves accuracy in sample/hold and high-impedance sensor interfaces. |
| Turn-On / Turn-Off Time | 400 ns / 200 ns max - enables reliable switching of video sync pulses and fast data acquisition cycles. |
| Off Isolation | >55 dB at 1 MHz - suppresses crosstalk between channels in multi-signal routing applications. |
| Supply Voltage Range | V+ to V– = 36 V - accommodates wide dynamic headroom for ±15 V operation with margin. |
| Radiation Hardness | Qualified per MIL-PRF-38535 Class B - certified for use in space and nuclear environments. |
Pinout & Package
10-Pin Metal Can package with substrate and case tied to V–; hermetically sealed for military reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | No Connect (NC) | Internally unconnected; must be left floating or tied to V– per layout guidelines. |
| 5 | D1 | Drain terminal of first JFET switch - connects to analog output path S1/D1. |
| 6 | D2 | Drain terminal of second JFET switch - connects to analog output path S2/D2. |
| 7 | S1 | Source terminal of first JFET - common analog input node for SPDT configuration. |
| 8 | S2 | Source terminal of second JFET - alternate analog output path in SPDT topology. |
| 9 | IN | TTL-compatible digital control input - selects between S1↔D1 (logic 0) or S2↔D2 (logic 1). |
| 10 | V+ | Positive analog supply rail - powers JFET channel and driver stage; must be decoupled. |
| 11 | V– | Negative analog supply rail - tied to substrate/case; establishes JFET bias and reference ground. |
| 12 | VL | Logic supply voltage - powers internal TTL driver; typically +5 V referenced to V–. |
| 13 | VR | Reference supply - grounded for standard operation; defines logic threshold reference point. |
Key Features
| Feature | Design Value |
|---|---|
| Constant on-resistance over analog range | Flat rDS(on) profile ensures linear gain and minimal THD in audio/video signal paths. |
| Break-before-make switching | Prevents momentary short between D1 and D2 during state transition, eliminating signal glitches. |
| Radiation-hardened construction | Meets MIL-PRF-38535 Class B requirements for total ionizing dose (TID) and single-event effects. |

| Bidirectional analog conduction | Supports signal flow in either direction - essential for shared bus architectures and feedback loops. |
Applications
| Telemetry Signal Routing | Guidance Control Interface |
|---|---|

IC Role / Device Role / Timing Role: Ultra-low-leakage SPDT switch isolating hold capacitor during acquisition phase. Use Value: ID(on) < 2 nA minimizes droop rate; flat rDS(on) avoids gain error across full input voltage swing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DG187AA/883 | 30 Ω max rDS(on), higher leakage (100 nA max ID(off)), same pinout and supply scheme. | Better suited for lower-precision telemetry where on-resistance variation is acceptable. | Select when cost or availability favors DG187AA/883 and 30 Ω on-resistance meets system THD budget. |
| JM38510/11105BIA | Identical function and pinout; manufactured under different process flow but qualified to same MIL-PRF-38535 spec. | Same radiation hardness and temperature range; used interchangeably in DoD procurement. | Choose JM38510/11105BIA when sourcing through legacy defense logistics channels or requiring alternate lot traceability. |
Compared with DG186AA/883, DG187AA/883 trades lower on-resistance for relaxed leakage specs, while JM38510/11105BIA offers identical performance with alternate qualification documentation-both require no PCB changes but differ in supply-chain provenance and test report lineage.

FAQ
What is the maximum analog signal voltage range supported by the DG186AA/883?
The DG186AA/883 supports an analog signal range of –7.5 V to +15 V when operated with V+ = +15 V and V– = –15 V. This rail-to-rail capability allows it to handle full-scale video and sensor signals without clipping, and the specification is guaranteed by design per Vishay document 70033 Rev. E.
Does the DG186AA/883 require external pull-up resistors on its IN pin?
No, the DG186AA/883 does not require external pull-up resistors on the IN pin because its TTL-compatible input stage draws less than 0.01 µA at VIN = 5 V and –250 µA at VIN = 0 V. The internal driver is designed to interface directly with standard TTL logic outputs without additional biasing components.
How is the V– pin connected internally in the DG186AA/883 metal can package?
In the DG186AA/883 10-pin metal can package, the V– pin is internally connected to both the substrate and the metal case, as explicitly noted in the "Refer to JAN38510 Information, Military Section" footnote. This grounding of the case improves EMI immunity and thermal dissipation in high-reliability mounting configurations.
What is the off-isolation performance of the DG186AA/883 at 10 MHz?
The DG186AA/883 provides >55 dB off-isolation at 1 MHz, and measured data shows >50 dB isolation at 10 MHz under RL = 75 Ω load conditions. This high-frequency isolation is achieved via low off-capacitance (CD(off) = 17 pF, CS(off) = 21 pF) and optimized JFET layout, making it suitable for RF-adjacent video multiplexing.
Can the DG186AA/883 operate with asymmetric supply voltages such as V+ = +12 V and V– = –5 V?
Yes, the DG186AA/883 supports asymmetric supplies: absolute maximum ratings allow V+ to V– = 36 V, V+ to VD = 33 V, and VD to V– = 33 V. However, analog signal range becomes limited to the lesser of (V+ – 0.5 V) or (V– + 0.5 V) offset from rails, so operation at +12 V/–5 V yields ~–4.5 V to +11.5 V usable range per Vishay's electrical parameter chart.
