74LCX540FT(AJ)

74LCX540FT(AJ) is a CMOS digital silicon monolithic IC. It is a high-performance CMOS octal bus buffer. It is designed for use in 3.3V systems, it achieves high-speed operation while maintaining the CMOS low power dissipation. This device is designed for low-voltage (3.3V) VCC applications, but it could be used to interface to 5V supply environment for both inputs and outputs. It is an inverting 3-state buffer having two active-low output enables. When either active-low OE1 or active-low OE2 are high, the terminal outputs are in the high-impedance state. This device is designed to be used with 3-state memory address drivers, etc. All inputs are equipped with protection circuits against static discharge. It is pin and function compatible with the 74 series (74LVC/ALVC/ etc.) 540 type.
