V_CC = 5.25 V, V_I = 0 V (All Outputs Disable)
Notes: 1. All typical values are at V_CC = 5 V, Ta = 25°C,VIC = 0.
2. Hysteresis is the differential between the positive going input threshold voltage and the negative
going input threshold voltage.
3. Not more than one output should be shorted at a time.
