Resistors R7 and R8 are 0 Ω resistors used by each channel's sense lines. There are also various input configurations offered by additional input side resistors. R1 and R2 are optional 100 Ω resistors for terminating an LVDS signal on the inputs of channel A and channel B, respectively. R3 and R5 are optional 50 Ω resistors if there is a need to terminate the noninverting inputs of each channel to a 50 Ω load. R4 and R6 are optional 0 Ω resistors if there is a need to ground the inverting inputs to establish the threshold level. R4 and R6 are intended for split supply operation of the TLV3602.
