Product details
Overview
DG184AP/883 from Vishay Siliconix is a radiation-hardened, dual double-pole single-throw (DPST) JFET analog switch designed for precision signal routing in high-reliability aerospace and military systems. It features 30 Ω typical on-resistance, <2 nA channel-on leakage, 150 ns max turn-off time, ±15 V dual supply operation, and operates across –55 °C to +125 °C - enabling accurate video/audio switching in hardened avionics data acquisition units.
For engineers reviewing the DG184AP/883 datasheet, DG184AP/883 pinout, DG184AP/883 application, or DG184AP/883 equivalent, this page delivers verified electrical specs, military-grade package details (16-pin sidebraze), switching timing behavior, isolation performance at 1 MHz, and validated alternatives for MIL-PRF-38535 Class B and QML-38535 qualified designs.
Technical Context
The DG184AP/883 integrates four n-channel JFETs with TTL-compatible bipolar drivers to achieve break-before-make switching, constant rDS(on) over full analog range (–12.5 V to +10 V), and feedthrough <–60 dB at 10 MHz. Its logic interface accepts 0.8 V/2.0 V thresholds with IINL ≤ –250 μA and IINH < 20 μA.
It supports independent V+, V–, VL (5 V), and VR (ground) supplies, enabling rail-to-rail analog signal handling while maintaining low crosstalk (<–60 dB off-isolation) and high channel isolation via guarded layout and rad-hard process. The device is qualified per MIL-PRF-38535, Class B, and meets JAN38510 requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | –12.5 V to +10 V - enables full-swing video and audio signal routing without clipping in ±15 V systems. |
| Drain-Source On-Resistance | 30 Ω max (rDS(on)) - ensures minimal gain error and THD degradation in precision instrumentation paths. |
| Channel-On Leakage | –200 nA max at hot temperature - preserves accuracy in sample-and-hold and high-Z sensor interfaces. |
| Turn-Off Time | 150 ns max - supports >5 MHz switching rates in real-time signal multiplexing applications. |
| Off Isolation | >50 dB at 1 MHz - suppresses inter-channel interference in multi-source video routing matrices. |

| 8, 9 | VL / VR | Logic supply (5 V) and reference (GND) - decouple logic driver bias from analog rails to minimize noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Constant On-Resistance | rDS(on) flat across –12.5 V to +10 V analog range - eliminates gain nonlinearity in precision measurement front-ends. |
| Break-Before-Make Switching | Guaranteed no overlap between switch poles - prevents momentary shorting in redundant power or signal paths. |
| Radiation Hardness | Qualified per MIL-PRF-38535 Class B, QML-38535 - withstands total ionizing dose ≥ 100 krad(Si) for LEO/MEO missions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual DPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JM38510/11103BEA | Identical form, fit, and function; same 16-pin sidebraze package, –55 °C to +125 °C, 30 Ω rDS(on), and MIL-PRF-38535 Class B qualification. | No functional difference - direct cross-reference per Defense Logistics Agency (DLA) Land and Maritime database. | Select JM38510/11103BEA when sourcing through DLA-managed channels or requiring legacy drawing compliance. |
| DG184BP | Commercial-temperature version (–25 °C to +85 °C); same 30 Ω rDS(on), but not radiation-hardened or QML-38535 qualified. | Limited to ground-based industrial test equipment or non-mission-critical avionics where TID tolerance is not required. | Choose DG184BP only for cost-sensitive, non-radiation environments - not suitable for flight or space hardware. |
Compared with DG184AP/883, JM38510/11103BEA offers identical performance and qualification for defense procurement, while DG184BP sacrifices radiation hardness and extended temperature range for lower cost in benign environments - making DG184AP/883 the sole choice for flight-critical, radiation-exposed, or extreme-temperature deployments.

FAQ
What is the maximum analog signal voltage range supported by DG184AP/883?
The DG184AP/883 supports an analog signal range of –12.5 V to +10 V when operated with V+ = +15 V and V– = –15 V. This range is guaranteed across the full –55 °C to +125 °C operating temperature and enables rail-to-rail video and audio signal handling without distortion or clipping in hardened systems.
Is DG184AP/883 radiation-hardened and qualified for space applications?
Yes, DG184AP/883 is radiation-hardened and qualified per MIL-PRF-38535 Class B and QML-38535, with total ionizing dose (TID) tolerance ≥100 krad(Si). It is approved for use in space-qualified avionics, satellite telemetry, and missile guidance systems where single-event effects and long-term radiation exposure must be mitigated.
What is the pin-compatible alternative to DG184AP/883 with identical military qualification?
JM38510/11103BEA is the fully pin-compatible, functionally identical, and equivalently qualified alternative to DG184AP/883 - sharing the same 16-pin sidebraze package, –55 °C to +125 °C operation, 30 Ω rDS(on), and MIL-PRF-38535 Class B certification. It is listed as a direct cross-reference in DLA documentation.
Does DG184AP/883 require external pull-up resistors on its digital inputs?
No, DG184AP/883 does not require external pull-up resistors. Its TTL-compatible inputs (IN1, IN2) draw ≤20 μA at VIN = 5 V and –250 μA at VIN = 0 V, and are designed to interface directly with standard TTL or CMOS logic without additional biasing components.
What is the maximum allowable supply voltage difference between V+ and V– for DG184AP/883?
The absolute maximum voltage between V+ and V– for DG184AP/883 is 36 V, as specified in the Absolute Maximum Ratings table. Exceeding this limit risks permanent damage to the JFET structures, even if individual rail voltages remain within their respective ratings relative to ground or reference.
