7.5 Electrical Characteristics

At VDD(MIN) ≤ VDD ≤ VDD (MAX), CTR1/MR = CTR2/MR = CTS1 = CTS2 = open, output reset pull-up resistor RPU = 10 kΩ,

voltage VPU = 5.5 V, and load CLOAD = 10 pF. The operating free-air temperature range TA = – 40°C to 125°C, unless

otherwise noted. Typical values are at TA = 25°C and VDD = 16 V and VIT = 6.5 V (VIT refers to VITN or VITP).
