MOTOROLA MC74LVX244DWR2, MC74LVX244DTR2, MC74LVX244DW Datasheet
SEMICONDUCTOR TECHNICAL DATA
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 7V, allowing the interface of 5V systems to 3V
systems.
