I am having hard time in finding what this component is . It has 8 pins and a marking on it says 500
. It has 2 pins on bottom on each side and two on each top side.
On the board 2 pins on left bottom are as inputs and two on the right are used as outputs.
I searched for it on SMD codeBook as well as this site but couldn't find anything.
I hope some one can help here. It is part of a rs485 circuitry on a board. There is another Sot23 marked W216j
I couldn't find this also. This is how they are connected. Please ignore the pin names on SOT23/IC1
**UPDTAE""
I have got the product and its the exact one by help provided by @Tom and @jp314 This is the product that was marked 500, The SOT package is quite lear but still I couldn't get the exact one.
