MC74HC244A

DATA SHEET www.onsemi.com Octal 3-State Noninverting Buffer/Line Driver/ Line Receiver MC74HC244A, MC74HCT244A The MC74HC244A is identical in pinout to the LS244. The MC74HC244A device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. The MC74HCT244A device inputs are compatible Standard CMOS or TTL outputs. The MC74HCT244A may be used as a level converter for interfacing TTL or NMOS outputs to High−Speed CMOS inputs. These octal noninverting buffer/line drivers/line receivers are designed to be used with 3−state memory address drivers, clock drivers, and other bus−oriented systems. The devices have noninverting outputs and two active−low output enables. The HC244A/HCT244A is the non−inverting version of the HC240A/HCT240A.
