DG540DJ

DG540DJ Description

The DG540DJ is a high-performance, quad single-pole single-throw (SPST) switch designed for video applications. Manufactured by Vishay / Siliconix, this interface IC chip is housed in a through-hole package, specifically a 20DIP tube. The DG540DJ offers a -3dB bandwidth of 500MHz, ensuring high-frequency performance suitable for demanding video applications. With a supply voltage range of ±3V to ±15V for dual supplies and 3V to 15V for single supplies, the DG540DJ provides flexibility in power requirements. Each of the four channels features a maximum on-state resistance of 60 ohms, minimizing signal loss and distortion. The switch circuit is designed as a 1:1 multiplexer/demultiplexer, making it ideal for signal routing and switching tasks. The DG540DJ is classified under ECCN EAR99 and HTSUS 8542.39.0001, with a REACH status of unaffected. The moisture sensitivity level (MSL) is rated at 1 (unlimited), ensuring robustness in various environmental conditions.
