10.2.2.2 FLT and RDY Pin Circuitry
A 50-kΩ pullup resistor is internally connected on the FLT and RDY pins. The FLT and RDY pins are an open-drain output. A 10-k? pullup resistor can be used to make it faster rise and to provide logic high when FLT and RDY is inactive, as shown in Figure 10-4.
Fast common mode transients can inject noise and glitches on FLT and RDY pins because of parasitic coupling. This is dependent on board layout. If required, additional capacitance (100 pF to 300 pF) can be included on the FLT and RDY pins.
