Note): R1, R2 and R3 are calculated from the capacitive loading and a 1µsec time constant on each bus node. For an
addition to an existing system, R2 (the new value for R2) is shown as being calculated from the parallel
combination of R2 and the scaled value of R3; while for a permanent system R2, and scaled values of R1 and
R3 have been used. Note that this example has used scaled resistor values and combined the node and cable
capacitances.
Check for maximum pull-up current:
= 17.6mA < 30mA

zOperation notes
1. About operation voltage supply range
Within operation voltage supply range, basic circuit function operation is guaranteed within operation ambient temp.
But please confirm set up of constant and element, voltage set up and temp set up on use.
2. About operation temp range
If it within recommended operation voltage range, circuit function operation is guaranteed within operation temp.
It corralled to conditions of power dissipation to temp.
Please watch out except condition stipulated by electrical characteristics within the range, it cannot guarantee standard
value of electrical characteristics. But it retains original function.
