74HCT74D - Dual D-type flip-flop
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
