Texas Instruments SN74HCT244/SN74HCT244-Q1 Buffers/Line Drivers

Texas Instruments SN74HCT244/SN74HCT244-Q1 Octal Buffers and Line Drivers are designed to improve the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. The Texas Instruments SN74HCT244/SN74HCT244-Q1 devices are organized as two 4-bit buffers or drivers with separate output-enable (OE) inputs. When OE is low, the device passes non-inverted data from the A inputs to the Y outputs. When OE is high, the outputs are in the high-impedance state. The SN74HCT244-Q1 devices are AEC-Q100 qualified for automotive applications.

Features
