(1) H = high voltage level, L = low voltage level, X = don't care
(2) L = driving low, H = driving high, TPUL2T122-Q1 TPUL2T122A-Q1 = driving high for the defined pulse width time, TPUL2T122-Q1 TPUL2T122A-Q1 = driving low for the defined pulse width time
(3) These outputs are based on the assumption that the indicated steady-state conditions at the inputs have been set up long enough to complete any output pulse.
(4) If an output pulse is triggered while a previous output pulse is still active, the output continues to drive high for one additional pulse width.
