6.6 Timing Requirements

At 1.9V ≤ VDD ≤ 42V, CTS = CTR = Open, RESET Voltage (VRESET) = 100kΩ to VDD, RESET load = 50pF, and over the operating free-air temperature range of –40°C to 125°C, unless otherwise noted. Typical values are at TA = 25°C.
MIN NOM MAX UNIT
tGI (VIT) Glitch Immunity undervoltage VITN(UV), 20% Overdrive(1) CTS = Open 5 µs
Glitch Immunity overvoltage VITP(OV), 20% Overdrive(1) CTS = Open 5 µs
(1) 20% Overdrive from threshold. Overdrive % = [VSENSE + VITP] / VITP
