Pull-up Resistor
Pull-down Resistor
Includes ±50K ohm internal.
Single edge is monotonic when transitioning through region.
Inputs with pull-ups/-downs are not included.
Internal leakage to ground is less than equal to 5 uA to ensure high level if input is floating.
Configuration is Rr=475 ohms at 1%. Iref=2.32 mA. Iref=VDD/(3 x Rr).
