description/ordering information  
This octal buffer/line driver is designed for 2.7-V to 3.6-V V  
operation.  
CC  
The SN74LVCZ244A 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.  
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.  
When V  
is between 0 and 1.5 V, the device is in the high-impedance state during power up or power down.  
CC  
However, to ensure the high-impedance state above 1.5 V, OE should be tied to V  
the minimum value of the resistor is determined by the current-sinking capability of the driver.  
through a pullup resistor;  
CC  
This device is fully specified for hot-insertion applications using I and power-up 3-state. The I circuitry  
off  
off  
disables the outputs, preventing damaging current backflow through the device when it is powered down. The  
power-up 3-state circuitry places the outputs in the high-impedance state during power up and power down,  
which prevents driver conflict.
