SN74LVCH244A OCTAL BUFFERS/DRIVERS

ORDERING INFORMATION The SN54LVCH244A octal buffer/line driver is designed for 2.7-V to 3.6-V VCC operation, and the SN74LVCH244A octal buffer/line driver is designed for 1.65-V to 3.6-V VCC operation. These devices 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 th.
