AC WAVEFORMS
Product speciï¬cation
74HC/HCT03
HC: VM = 50%; VI = GND to VCC
HCT: VM = 1.3 V; VI = GND to 3 V.
Fig.6 Waveforms showing the input (nA, nB) to output (nY) propagation delays and the output transition times.
TEST CIRCUIT AND WAVEFORMS
Fig.7 Test circuit (open drain)
Fig.8 Input pulse definitions.
Deï¬nitions for Figs. 7, 8:
CL = load capacitance including jig and probe
capacitance
(see AC CHARACTERISTICS for values).
RT = termination resistance should be equal to the
output impedance ZO of the pulse generator.
tr = tf = 6 ns; when measuring fmax, there is no
constraint on tr, tf with 50% duty factor.
