1、General Description
The AiP74HC/HCT74 are dual positive edge triggered D-type flip-flop. They have individual data (nD),
—
—
—
clock (nCP), set (nSD) and reset (nRD) inputs, and complementary nQ and nQ outputs. Data at the
nD-input, that meets the set-up and hold time requirements on the LOW-to-HIGH clock transition, is
stored in the flip-flop and appears at the nQ output. Schmitt-trigger action in the clock input, makes the
circuit highly tolerant to slower clock rise and fall times. Inputs include clamp diodes. This enables the use
of current limiting resistors to interface inputs to voltages in excess of VCC.

[1] tpd is the same as tPLH and tPHL.
[2] tt is the same as tTHL and tTLH.
[3] CPD is used to determine the dynamic power dissipation (PD in uW).
PD=(CPD×VCC2×fi×N)+∑(CL×VCC2×fo) where:
fi=input frequency in MHz;
fo=output frequency in MHz;
CL=output load capacitance in pF;
VCC=supply voltage in V;
N=number of inputs switching;
∑(CL×VCC2×fo)=sum of outputs.
