DG184AP/883

Analog Switches, Multiplexers, Demultiplexers Overview

The DG184AP/883 is a precision dual double-pole, single-throw (DPST) analog switch manufactured by Vishay Siliconix. It utilizes n-channel JFET transistors and a TTL-compatible bipolar driver to provide accurate switching of video and audio signals. The device features a constant on-resistance over the entire analog range, with a typical rDS(on) of 25 Ω at room temperature and a maximum of 30 Ω across the full operating temperature range (-55°C to +125°C). It operates with supply voltages up to ±15 V and supports an analog signal range of -7.5 V to +15 V. Key electrical characteristics include low leakage current (ID(off) max 100 nA), high channel isolation (>60 dB at 10 MHz), and fast switching times (tON/tOFF approx. 110 ns to 130 ns).

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify that the component matches the specific military-grade suffix AP/883 and the JAN38510 standard. Confirm the package type is the 16-pin sidebraze configuration. Ensure the supplier provides traceability documentation consistent with the specified operating temperature range of -55°C to +125°C.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the DG184AP/883 when a moderate on-resistance of approximately 25 Ω is required alongside strict requirements for low leakage and high isolation. This model offers a balance between the lower resistance of the DG183 and the higher resistance of the DG185. Verify that the application can accommodate the specific analog voltage ranges supported by the dual DPST architecture.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG183/184/185 series of high-speed drivers and dual DPST JFET switches. The series is designed for precision analog signal switching where flat on-resistance and low distortion are critical. The DG184 variant specifically targets applications requiring a middle-ground on-resistance value compared to its siblings.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same family include the DG183AP/883 (lower on-resistance) and the DG185AP/883 (higher on-resistance). Cross-family replacements require careful evaluation of on-resistance, leakage, and switching speed parameters to ensure compatibility with the existing circuit design.
