General
The 74LCX240FT 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) V
CC
applications,
but it could be used to interface to 5 V supply environment for
both inputs and outputs.
The 74LCX240FT 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.
