74HC74D: Dual D-type flip-flop with set and reset; positive-edge trigger
The 74HC74 and 74HCT74 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 that enable the use of current
limiting resistors to interface inputs to voltages in excess of VCC.
