Notes:
1. All typical values are at T_A = 25°C unless otherwise stated.
2. AC voltage is instantaneous voltage.
3. A logic “Low” output level at pin 6 occurs under the conditions of V_IN ≥ V_TH+ as well as the range of V_IN > V_TH– once V_IN has exceeded V_TH+.
4. A logic “High” output level at pin 6 occurs under the conditions of V_IN ≤ V_TH– as well as the range of V_IN < V_TH+ once V_IN has decreased below V_TH–.
