Octal Bus Buffer
BUS BUFFER fabricated using silicon gate CMOS technology.
Designed for use in 3-V systems, it achieves high-speed operation
while maintaining the CMOS low power dissipation. This device
is suitable for low-voltage and battery operated systems.
TC74LVX244 is non-inverting. Both devices have two active-low
output enables. These devices are designed to be used in such
applications as 3-state memory address drivers.
applied to the input pins without regard to the supply voltage.
This device can be used to interface 5V to 3V systems and two
supply systems such as battery back up. This circuit prevents
device destruction due to mismatched supply and input voltages.
