AC WAVEFORMS
Product specification
74HC/HCT03
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 (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.
Definitions for Figs. 7, 8:
C_L = load capacitance including jig and probe
capacitance
(see AC CHARACTERISTICS for values).
R_T = termination resistance should be equal to the
output impedance Z_O of the pulse generator.
t_r = t_f = 6 ns; when measuring f_max, there is no
constraint on t_r, t_f with 50% duty factor.
