DESCRIPTION/ORDERING INFORMATION  
The SN74LVCH244A octal buffer/line driver is designed for 2.7-V to 3.6-V VCC operation.  
This device is organized as two 4-bit line drivers with separate output-enable (OE) inputs. When OE is low, this  
devices passes data from the A inputs to the Y outputs. When OE is high, the outputs are in the high-impedance  
state.  
Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors  
with the bus-hold circuitry is not recommended.  
Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of this device as a translator in  
a mixed 3.3-V/5-V system environment.  
This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs,  
preventing damaging current backflow through the device when it is powered down.  
To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
