DESCRIPTION
The 74ALVC74 is a dual positive-edge triggered, D-type
flip-flop with individual data (D), clock (CP), set (SD) and
reset (RD) inputs and complementary Q and Q outputs.
The set and reset are asynchronous active LOW inputs
and operate independently of the clock input. Information
on the data input is transferred to the Q output on the
LOW-to-HIGH transition of the clock pulse. The D inputs
must be stable one set-up time prior to the LOW-to-HIGH
clock transition for predictable operation.
Schmitt-trigger action in the clock input makes the circuit
highly tolerant to slower clock rise and fall times.

VCC = 2.7 V; CL = 50 pF; RL = 500

Notes
1. CPD is used to determine the dynamic power dissipation (PD in µW).
PD = CPD × VCC2 × fi × N + Σ(CL × VCC2 × fo) where:
fi = input frequency in MHz;
fo = output frequency in MHz;
CL = output load capacitance in pF;
VCC = supply voltage in Volts;
N = total load switching outputs;
Σ(CL × VCC2 × fo) = sum of the outputs.
2. The condition is VI = GND to VCC.
