74HC74 SMD Integrated

74HC74 is a double positive edge triggered D-type flip-flop IC. There are independent data (nD), clock (nCP), set (nSD) and reset (nRD) inputs and complementary nQ and nQ outputs. Data at the ND input that meets the setup and hold time requirements for the LOW to HIGH clock transition are stored in the flip-flop and appear at the nQ output.

 

The Schmitt-trigger action at the clock input causes the circuit to become more This makes it very tolerant of slow clock rise and fall times. Inputs include clamp diodes that enable the use of current limiting resistors to interface the inputs to voltages exceeding VCC.
