The HC374, HCT374, HC574, and HCT574 are octal D-type flip-flops with 3-state outputs and the capability to drive 15 LSTTL loads. The eight edge-triggered flip-flops enter data into their registers on the LOW to HIGH transition of clock (CP). The output enable (OE) controls the 3-state outputs and is independent of the register operation. When OE is HIGH\, the outputs are in the high-impedance state. The 374 and 574 are identical in function and differ only in their pinout arrangements.
