Product specification
74HC/HCT4515
(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 input (A_n, LE, E) 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.
(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 minimum pulse width of the latch enable input (LE) and the set-up and hold times
for LE to A_n. Set-up and hold times are shown as positive values but may be specified as negative values.
