Protection Characteristics
Note: Characteristics show the deviation of parameters at given supply voltage and junction temperature. Typical
values show the typical parameters expected from manufacturing.
Electrical Characteristics: Protection
All voltages with respect to ground, positive currents are flowing into pin
unless otherwise specified: VDD = 4.5V to 5.5V, Tj = -40°C to +150°C
