(1) HC : V_M = 50%; V_I = GND to V_CC.
HCT: V_M = 1.3 V; V_I = GND to 3 V.
Fig.6 Waveforms showing the clock (CP) to output (Q_n) propagation delays, the clock pulse width, the output
transition times and the maximum clock frequency.
(1) HC : V_M = 50%; V_I = GND to V_CC.
HCT: V_M = 1.3 V; V_I = GND to 3 V.
Fig.7 Waveforms showing the 3-state enable and disable times.
The shaded areas indicate when the input is
permitted to change for predictable output
performance.
(1) HC : V_M = 50%; V_I = GND to V_CC.
HCT: V_M = 1.3 V; V_I = GND to 3 V.
Fig.8 Waveforms showing the set-up and hold times from the D_n, D_SR, D_SL and S_n inputs to the clock (CP).
