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.13 Waveforms showing the latch disable input
(LD) 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.14 Waveforms showing the blanking (BI) to
output (Q_n) propagation delays and the
output transition times.
The shaded areas indicate when the input is permitted to
change for predictable output performance.
