Description

The SN54LVCH244A octal buffer/line driver is designed for 2.7-V to 3.6-V V_CC  operation and the SN74LVCH244A octal buffer/line driver is designed for 1.65-V to 3.6-V V_CC  operation.

These devices SN74LVCH244A are organized as two 4-bit line drivers with separate output-enable (OE) inputs. When OE is low,these devices pass data from the A inputs to the Y outputs. When OE is high, the outputs are in the high-impedance state.
