DG184AP

Analog Switches, Multiplexers, Demultiplexers Overview

The DG184AP is a precision dual double-pole, single-throw (DPST) analog switch manufactured by Vishay Siliconix. It features an on-resistance of 30 ohms at room temperature and up to 60 ohms across the full operating range. The device supports a maximum supply voltage of 36 V between V+ and V–, with a recommended configuration of ±15 V. It operates within a temperature range of -55 °C to +125 °C and utilizes a 16-pin sidebraze package. The switch handles a saturation drain current of 30 mA and maintains low leakage currents below 1 nA.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm that the specific suffix matches the required military or extended temperature specifications. Review datasheet revision history for any updates to electrical characteristics or mechanical dimensions before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the DG184AP when a moderate on-resistance of 30 ohms is acceptable compared to lower resistance alternatives like the DG183. Ensure the design accommodates the 16-pin sidebraze package requirements. Verify that the application logic levels align with the specified TTL-compatible bipolar driver inputs for reliable switching performance.

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 applications requiring flat JFET on-resistance characteristics. The DG184 variant specifically targets use cases where a balance between speed, isolation, and resistance is necessary for video and audio signal integrity.
