AC WAVEFORMS

Product specification

74HC/HCT4515

(1) HC : VM = 50%; VI = GND to VCC.

HCT: VM = 1.3 V; VI = GND to 3 V.

Fig.6 Waveforms showing the input (An, LE, E) to output (Qn) propagation delays and the output transition times.

The shaded areas indicate when the input is

permitted to change for predictable output

performance.

(1) HC : VM = 50%; VI = GND to VCC.

HCT: VM = 1.3 V; VI = 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 An. Set-up and hold times are shown as positive values but may be specified as negative values.
