74LCX240  
Low-Voltage Octal Buffer/Line Driver  
with 5V Tolerant Inputs and Outputs  
Y
Power-down high impedance inputs and outputs  
General Description  
The LCX240 is an inverting octal buffer and line driver de-  
signed to be employed as a memory address driver, clock  
driver and bus oriented transmitter or receiver. The device is  
designed for low voltage (3.3V) V applications with capa-  
CC  
bility of interfacing to a 5V signal environment.
