74LVC2G74

Single D-type ﬂip-ﬂop with set and reset; positive edge trigger

Test data is given in Table 11.

Deﬁnitions for test circuit:

RL = Load resistance.

CL = Load capacitance including jig and probe capacitance.

RT = Termination resistance should be equal to the output impedance Zo of the pulse generator.

VEXT = External voltage for measuring switching times.
