3 Description

This octal buffer/line driver is designed for 2.7-V to 3.6-V VCC 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.
