description/ordering information
This octal buffer/line driver is designed for 2.7-V to 3.6-V VCC operation.
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 VCC is between 0 and 1.5 V, the device is in the high-impedance state during power up or power down.
However, to ensure the high-impedance state above 1.5 V, 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.
This device is fully specified for hot-insertion applications using Ioff and power-up 3-state. The Ioff circuitry
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.
