3 Description
This octal buffer/line driver is designed for 2.7-V to
3.6-V V_CC operation.
The SN74LVCZ244A device 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.
