DESCRIPTION  
The U74HC240 is a octal buffer and line driver with 3-state outputs.  
It is organized as two 4-bit buffers/drivers with separate  
output-enable ( OE ) inputs. When OE is high, the Y outputs are  
in a high-impedance state and the outputs neither load nor drive  
the bus lines. When OE is low, the device passes inverted data  
from the A inputs to the Y outputs.  
The U74HC240 is designed to improve the performance and  
density of 3-state memory address drivers, clock drivers and  
bus-oriented receivers and transmitters.  
To ensure the high-impedance state during power up or power  
down, OE should be tied to VCC through a pull-up resistor; and  
the minimum value of the resistor is determined by the  
current-sinking capability of the driver.  
„
FEATURES  
* Wide supply voltage range from 2V to 6V  
* Max tpd of 9 ns from A to Y at 6V  
* Low power consumption, ICC = 8 μA (Max.) at 6V  
* ±6 mA output driver at 5V  
* Low Input Current of 1 μA Max
