Product details
Overview
DG180AP from Vishay Siliconix is a radiation-hardened, dual SPST analog switch using JFET technology for precision audio/video signal routing in aerospace and defense systems. It features 10 Ω typical on-resistance (rDS(on)), <2 nA channel-on leakage (ID(on)), 240 ns turn-on time, ±15 V analog signal range (–7.5 V to +15 V), and operates across –55 °C to +125 °C in a hermetic 14-pin sidebraze metal package.
For engineers reviewing the DG180AP datasheet, DG180AP pinout, DG180AP application, or DG180AP equivalent, this page delivers verified military-grade switching performance metrics, radiation hardness context, analog signal integrity data, and direct replacement guidance for high-reliability embedded timing and signal path design.
Technical Context
The DG180AP integrates four n-channel JFETs with TTL-compatible bipolar drivers to enable bidirectional conduction in the on-state and block up to 20 V peak-to-peak signals in the off-state with <–60 dB off-isolation at 10 MHz. Its flat on-resistance over the full analog range eliminates large-signal distortion in precision applications.
It requires three independent supply rails: V+ (+15 V), V– (–15 V), and VL (+5 V) for logic control, with VR tied to ground. Logic inputs accept 0.8 V low / 2.0 V high thresholds, and substrate/case is internally connected to V– for stable reference and fault protection.

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 |
|---|---|---|---|
| DG181AP/883 | 30 Ω max rDS(on), higher leakage (100 nA max ID(on)), same package/temp grade | Better suited for lower-precision, higher-voltage analog routing where on-resistance flatness is less critical | Select DG181AP/883 only if system tolerates higher on-resistance and reduced signal fidelity |
| ADG1419BRUZ | CMOS-based, 1.5 Ω rDS(on), but not radiation-hardened; commercial temp only (–40 °C to +125 °C) | Applicable in non-military industrial controls where rad-hard is unnecessary and lower on-resistance is prioritized | Choose ADG1419BRUZ only for cost-sensitive terrestrial applications without radiation or extended temp requirements |
Compared with DG180AP, DG181AP/883 trades signal fidelity for wider voltage margin tolerance, while ADG1419BRUZ offers superior on-resistance but lacks radiation hardening and military temperature certification - making DG180AP irreplaceable in certified aerospace signal routing.

FAQ
What is the maximum analog signal voltage range supported by the DG180AP?
The DG180AP supports an analog signal range of –7.5 V to +15 V under standard operating conditions (V+ = +15 V, V– = –15 V). This range is guaranteed by design and enables full-rail video and audio signal handling without clipping or distortion. The device blocks up to 20 V peak-to-peak in the off-state, and absolute maximum ratings allow V+ to V– up to 36 V for system-level margin.
Is the DG180AP radiation-hardened, and what qualification standards does it meet?
Yes, the DG180AP is radiation-hardened and qualified per MIL-PRF-38535 Class V and JAN38510/11101CA specifications. It meets total ionizing dose (TID) and single-event effect (SEE) requirements for space and high-altitude defense applications. The 14-pin sidebraze metal package and V–-tied substrate provide intrinsic latch-up immunity and ESD robustness consistent with these standards.
How does the DG180AP achieve constant on-resistance over its analog range?
The DG180AP achieves constant on-resistance through its JFET-based architecture and matched transistor design, which minimizes rDS(on) variation across the full –7.5 V to +15 V analog signal range. This flat resistance profile eliminates gain nonlinearity and harmonic distortion, directly enabling high-fidelity audio/video switching and precision sample/hold operation without calibration.
What are the logic interface requirements for controlling the DG180AP switches?
The DG180AP requires three logic supplies: VL = +5 V (pin 14), VR = GND (pin 1), and TTL-compatible inputs at IN1 (pin 10) and IN2 (pin 13). A logic low (≤0.8 V) turns the corresponding switch ON; a logic high (≥2.0 V) turns it OFF. Input currents are <20 µA high and –250 µA low, ensuring compatibility with standard TTL and CMOS drivers without loading.
Can the DG180AP be used in bidirectional signal paths, and how is that implemented?
Yes, the DG180AP supports fully bidirectional analog signal flow. Each SPST switch (S1–D1 and S2–D2) conducts equally well in either direction when ON, with symmetric on-resistance and leakage characteristics. This allows flexible routing in systems where signal direction may reverse - such as duplex telemetry interfaces - without requiring external diodes or directional logic.
