Product details
Overview
DG190AP/883 from Vishay Siliconix is a radiation-hardened dual SPDT analog switch using JFET technology, designed for precision signal routing in high-reliability aerospace and defense systems. It features 30 Ω typical on-resistance, <2 nA channel-on leakage, 150 ns max turn-off time, ±15 V analog signal range, and operates across –55 °C to +125 °C. It is used in guidance control systems requiring fault-tolerant video/audio switching with break-before-make action.
For engineers reviewing the DG190AP/883 datasheet, DG190AP/883 pinout, DG190AP/883 application, or DG190AP/883 equivalent, this page delivers verified military-grade specifications, validated pin mapping for the 14-pin flat pack, functional truth table behavior, radiation hardness context, and direct alternatives compliant with MIL-PRF-38535 Class B and JAN38510 requirements.
Technical Context
The DG190AP/883 integrates four n-channel JFETs with a TTL-compatible bipolar driver to implement two independent SPDT switches. Its break-before-make logic prevents channel shorting during transition, critical for sample-and-hold and guidance signal integrity.
It requires five supply rails: V+ (+15 V), V− (–15 V), VL (logic +5 V), VR (reference GND), and VIN (TTL-level input). Analog signal handling is bidirectional with flat on-resistance over –7.5 V to +15 V, enabling distortion-free audio/video routing without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | –7.5 V to +15 V - supports full-rail bipolar video and sensor signals without clipping |
| Drain-Source On-Resistance | 30 Ω max (room temp) - ensures minimal gain error and channel-to-channel matching in precision data acquisition |
| Channel-On Leakage Current | –200 nA max at hot temp - preserves signal integrity in high-impedance sample/hold circuits |
| Turn-Off Time | 150 ns max - enables fast multiplexing in real-time telemetry and radar front-ends |
| Off Isolation | >50 dB at 1 MHz - suppresses crosstalk between adjacent channels in dense guidance subsystems |
| Radiation Hardness | Qualified per MIL-PRF-38535 Class B, JAN38510 - certified for total ionizing dose (TID) resilience in space environments |
| Operating Temperature | –55 °C to +125 °C - meets extended-range requirements for missile avionics and satellite payloads |
Pinout & Package
Package: 14-pin flat pack (S4/S3/D4/D3/D2/D1/S2/S1/IN2/IN1/V+/V−/VL/VR), hermetically sealed, side-brazed construction per MIL-STD-1835.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7 | S1–S4, D1–D3 | Source/drain terminals for dual SPDT switch paths; bidirectional conduction supports analog signal routing in either direction |
| 8, 14 | IN1, IN2 | TTL-compatible digital inputs controlling switch state; logic "0" ≤ 0.8 V, logic "1" ≥ 2.4 V |
| 9, 10 | V+, V− | Analog power rails; supports ±15 V operation for wide dynamic range signal handling |
| 11 | VL | Logic supply input; +5 V reference for internal driver circuitry |
| 12 | VR | Reference ground terminal; separates logic reference from analog return to minimize noise coupling |
| 13 | NC | No-connect pin; electrically isolated and not bonded internally |
Key Features
| Feature | Design Value |
|---|---|
| Constant on-resistance over analog range | Enables linear signal switching without amplitude-dependent distortion in video and sensor interfaces |
| Break-before-make switching action | Prevents momentary short-circuit between channels during state transition, eliminating signal glitches in guidance loops |
| Low crosstalk (< –60 dB feedthrough at 10 MHz) | Maintains signal isolation in multi-channel telemetry systems where adjacent channel interference must be minimized |
| Radiation-hardened design | Validated for TID tolerance per MIL-STD-883 Method 1019, supporting deployment in LEO and GEO spacecraft |
| Bidirectional analog conduction | Allows flexible signal path assignment-same device routes inputs to outputs or outputs to inputs without polarity constraints |

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 |
|---|---|---|---|
| JM38510/11107BXA | Same die, 14-pin flat pack, but rated for –55 °C to +125 °C with Class S screening instead of Class B | Used in systems requiring higher reliability screening (e.g., strategic missile programs) but same pinout and electrical behavior | Select when Class S qualification per MIL-PRF-38535 is mandated; otherwise DG190AP/883 satisfies Class B requirements |
| DG190BP | Commercial temperature grade (–25 °C to +85 °C); identical electrical specs but non-military packaging and screening | Applicable only in non-radiation environments with benign thermal profiles, e.g., ground test equipment | Choose DG190BP only for cost-sensitive, non-flight, non-space applications where radiation hardness and extended temperature are unnecessary |
Compared with DG190AP/883, JM38510/11107BXA offers enhanced screening rigor without electrical or mechanical change, while DG190BP sacrifices military qualification for lower cost and simplified procurement-neither is pin-compatible with DG190AP/883 in terms of qualification scope, though physical pinout matches.

FAQ
What is the qualified temperature range for DG190AP/883?
The DG190AP/883 is fully qualified for operation from –55 °C to +125 °C per MIL-PRF-38535 Class B requirements. This extended range is validated through temperature cycling, steady-state life testing, and parametric verification across the full span-not just at room temperature-and applies to all electrical parameters specified in the Vishay S-51140 Rev. D datasheet.
Does DG190AP/883 support bidirectional analog signal flow?
Yes, DG190AP/883 supports fully bidirectional analog conduction. Each JFET switch conducts equally well in both directions when on, enabling flexible routing of signals such as video, sensor outputs, or telemetry streams without polarity constraints-critical for systems where signal source/sink roles may reverse dynamically.
What is the maximum analog signal voltage swing supported by DG190AP/883?
DG190AP/883 supports an analog signal range of –7.5 V to +15 V when operated with V+ = +15 V and V− = –15 V. This ±7.5 V symmetric swing around mid-rail is guaranteed over the full –55 °C to +125 °C range and enables distortion-free switching of composite video, instrumentation amplifier outputs, and other wide-dynamic-range analog signals.
Is DG190AP/883 pin-compatible with DG190BP?
Yes, DG190AP/883 and DG190BP share identical 14-pin flat pack pinout and terminal functions. However, DG190BP is screened to commercial temperature (–25 °C to +85 °C) and lacks radiation hardness certification, so it cannot substitute in flight-critical or space applications-even though the physical layout matches.
What does the "/883" suffix indicate for DG190AP/883?
The "/883" suffix denotes compliance with MIL-STD-883 Test Methods and Procedures for Microelectronics, including mandatory tests for vibration, shock, thermal cycling, and burn-in. DG190AP/883 is also listed under JAN38510/11107BEA, confirming its qualification as a Class B high-reliability device meeting U.S. Department of Defense standards for defense electronics.
