PARAMETER TEST CONDITIONS MIN TYP MAX UNIT
tPHL Propagation delay time, high-to-low (1) CL = 15 pF 250 ns
CL = 4 nF 450 ns
tPLH Propagation delay time, low-to-high (1) CL = 15 pF 250 ns
CL = 4 nF 500 ns
tR Rise time 20% to 80%, CL = 15 pF 18 ns
20% to 80%, CL = 4 nF 0.3 µs
tF Fall time 20% to 80%, CL = 15 pF 10 ns
20% to 80%, CL = 4 nF 0.26 µs
tSTART Power-up time (2) 45 µs
(1) High-to-low and low-to-high refers to the transition at the input.
(2) During power on, VS must exceed 3.3 V for tON before the output is in a correct state.
