The TC74LCX240 is a high-performance CMOS octal bus buffer. Designed for use in 3.3-V systems, it achieves high-speed operation while maintaining the CMOS low power dissipation. The device is designed for low-voltage (3.3 V) VCCapplications, but it could be used to interface to 5-V supply environment for both inputs and outputs. The 74LCX240F/FT is an inverting 3-state buffer having two active-low output enables. This device is designed to be used with 3-state memory address drivers, etc. All inputs are equipped with protection circuits against static discharge.
