Propagation Delay Input overdrive = 10mV (Note 3) 500 tPHL ns Output High to Low Input overdrive = 100mV (Note 3) 100 Propagation Delay Input overdrive = 10mV (Note 3) 500 tPLH ns Output Low to High Input overdrive = 100mV (Note 3) 100
Note 1:
All devices are production tested at +25°C. All temperature limits are guaranteed by design.
Note 2:
Supply current when output is high.
Note 3:
Input overdrive is the overdrive voltage beyond the offset and hysteresis-determined trip points.
