6.7 Switching Characteristics

Over the operating temperature range of TJ = –40°C to 125°C, 1.8 V < VDD < 6.5 V, RRESETn (n = 1, 2, 3, 4) = 100 kΩ to VDD (TPS386000 only), CRESETn (n = 1, 2, 3, 4L, 4H) = 50 pF to GND, RWDO = 100 kΩ to VDD, CWDO = 50 pF to GND, VMR = 100 kΩ to VDD, WDI = GND, and CTn (n = 1, 2, 3, 4) = open, unless otherwise noted. Typical values are at TJ = 25°C.
