(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 (D_n, LT) to
output (Q_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 input (LE) to output
(Q_n) propagation delays and the latch
enable pulse width.
(1) HC : V_M = 50%; V_I = GND to V_CC.
HCT: V_M = 1.3 V; V_I = GND to 3 V.
Fig.10 Waveforms showing the input (BI) to output
(Q_n) propagation delays.
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.11 Waveforms showing the data set-up and
hold times for D_n input to LE input.
