Description

This octal buffer/line driver SN74LVC2244A is designed for 1.65-V to 3.6-V V_CC  operation.

The SN74LVC2244A 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 OEis high, the outputs are in the high-impedance state.
