description  
This octal buffer/line driver is designed for 1.65-V to 3.6-V V  
operation.  
CC  
The SN74ALVCH244 is organized as two 4-bit line 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.  
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.  
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.  
The SN74ALVCH244 is characterized for operation from –40°C to 85°C.
