SL74HCT574 Overview
SL74HCT574 Octal 3-State Noninverting D Flip-Flop High-Performance Silicon-Gate CMOS The SL74HCT574 is identical in pinout to the LS/ALS574. This device may be used as a level converter for interfacing TTL or NMOS outputs to High-Speed CMOS inputs. Data meeting the setup time is clocked to the outputs with the rising edge of the Clock.
