description  
This octal buffer/driver is designed for 1.65-V to 3.6-V V  
operation.  
CC  
The SN74LVC240A is designed specifically to improve the performance and density of 3-state memory address  
drivers, clock drivers, and bus-oriented receivers and transmitters.  
This device is organized as two 4-bit buffers/drivers with separate output-enable (OE) inputs. When OE is low,  
the device passes data from the A inputs to the Y outputs. When OE is high, the outputs are in the  
high-impedance state.  
Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators  
in a mixed 3.3-V/5-V system environment.  
To ensure the high-impedance state during power up or power down, OE should be tied to V through a pullup  
CC  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.  
This device is fully specified for partial-power-down applications using I . The I circuitry disables the outputs,  
off  
off  
preventing damaging current backflow through the device when it is powered down.  
The SN74LVC240A is characterized for operation from –40°C to 85°C.
