DESCRIPTION/ORDERING INFORMATION  
The SN54LVCH244A octal buffer/line driver is designed for 2.7-V to 3.6-V VCC operation, and the  
SN74LVCH244A octal buffer/line driver is designed for 1.65-V to 3.6-V VCC operation.  
These devices are organized as two 4-bit line drivers with separate output-enable (OE) inputs. When OE is low,  
these devices pass 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 these devices as translators  
in a mixed 3.3-V/5-V system environment.  
These devices are fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the  
outputs, preventing damaging current backflow through the devices when they are 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.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas  
Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
