Need Help to Identified Unknown Components-746, 748, 840

Hello, we are doing reverse engineering PCB and found few components which we could not identified. We have try to ask via our supplier none of them could provide help. At first we thought the Device with SOIC-8 Package was an IC, upon further checking our design team discover the circuit is similiar to Resistor Network.
