7.5 Electrical Characteristics

At VDD(MIN) ≤ VDD ≤ VDD(MAX), CTR = CTS = open, output RESET pull-up resistor RPU = 10kΩ, voltage VPU = 5.5V, output BIST pull-up resistor RPU_BIST = 10kΩ, voltage VPU_BIST = 5.5V, and load CLOAD = 10pF. The operating free-air temperature range TA = – 40°C to 125°C, unless otherwise noted. Typical values are at TA = 25°C and VDD = 12V and VIT = 6.5V (VIT refers to VITN or VITP).

(1) When VDD voltage falls below UVLO, RESET is asserted. VDD slew rate ≤ 100mV / µs
(2) VPOR is the minimum VDD voltage for a controlled output state. Below VPOR, the output cannot be determined. VDD slew rate ≤ 100mV/µs
(3) For adjustable voltage guidelines and resistor selection refer to Adjustable Voltage Thresholds in Application and Implementation section
(4) Hysteresis is with respect to VITP and VITN voltage threshold. VITP has negative hysteresis and VITN has positive hysteresis.
(5) For VOH and VOL relation to output variants refer to Timing Figures after the Timing Requirement Table
