Electrical Characteristics (continued)
* On the OR2TxxB devices, the pull-up resistor will externally pull the pin to a level 1.0 V below VDD.
Table 31B. OR2TxxB Electrical Characteristics
OR2TxxB Commercial: VDD = 3.0 V to 3.6 V, 0 °C
≤ TA ≤ 70 °C; OR2TxxB Industrial: VDD = 3.0 V to 3.6 V, –40 °C ≤ TA ≤ +85°C.
