5.1.3 Diodes and Inputs Connected in Series
Vdrop across the diode Max. 4V
No more than 2 LEDs should be connected in series.
5.1.4 Resistors and Inputs Connected in Parallel
Parallel resistance Rp: FX
1N
= 15k
Ω
. If resistance Rp is less than the stated value, then add
Rb. See equation 1 for Rb calculation.
Alternatively; Current leakage: FX
1N
= 1.5mA. If the current leakage is greater than the stated
value, then add Rb. See equation 2 for Rb calculation.
