description

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 these devices as translators

in a mixed 3.3-V/5-V system environment.

the minimum value of the resistor is determined by the current-sinking capability of the driver.

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.

The SN74LVCZ244A is characterized for operation from –40

°C to 85°C.
