10.2.2.2 FLT and RDY Pin Circuitry
There is 50k pullup resistor internally on FLT and RDY pins. The FLT and RDY pin is an open-drain output. A 10-kΩ 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 due to 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.
