TC74LVX244 Non-Inverted, 3-State Outputs

The TC74LVX240,244F/ FT is a high-speed CMOS OCTAL

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.

The TC74LVX240 is an inverting 3-state buffer while the

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.

TC74LVX240FT, TC74LVX244FT

An input protection circuit ensures that 0 to 5.5V can be

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.
