Low-Voltage CMOS Octal Buffer Flow Through Pinout   
With 5V–Tolerant Inputs and Outputs (3–State, Inverting)
   
The MC74LCX540 is a high performance, inverting octal buffer operating from a 2.3 to 3.6V supply. This device is similar in function to the MC74LCX240, while providing flow through architecture.
