AC WAVEFORMS
Fig.7 Waveforms showing the definition of V_T+,
V_T− and V_H.
(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 input (A_n) to output (Y_n) propagation delays and the output transition times.
(1) HC : V_M = 50%; V_I = GND to V_CC.
HCT: V_M = 1.3 V; V_I = GND to 3 V.
Fig.9 Waveforms showing the 3-state enable and disable times.
