Overview
MC74LVX244 Octal Bus Buffer With 5V−Tolerant Inputs The MC74LVX244 is an advanced high speed CMOS non−inverting 3−state octal bus buffer and has two active low output enables.
It is also designed to work with 3−state memory address drivers, etc.
The inputs tolerate voltages up to 7.
0 V, allowing the interface of 5.
0 V systems to 3.
0 V systems.
