H = High voltage level I0 – I7 = The level of the steady state input at the respective I/O terminal is loaded into the flip–flop while the flip–flop outputs ( except Q7) are isolated from the I/O terminal. L = Low voltage level NC= No change O0 – O7 = The level of the respective Qn flip–flop prior to the last clock Low–to–High transition X = Don’t care Z = High impedance ”off” state * = When the OE input is High, all I/O terminals are at the High impedance state, sequential operation or cleaning of the register is not affected. ↑ = Low–to–High clock transition ↑ = Not Low–to–High clock transition |
