Description

General part information

SN74LV244AT Series

This octal buffer/driver is designed specifically to improve both the performance and density of 3-state memory-address drivers, clock drivers, and bus-oriented receivers and transmitters.

The SN74LV244AT is organized as two 4-bit buffers/line drivers with separate output-enable (OE) inputs. WhenOEis low, the device passes data from the A inputs to the Y outputs. WhenOEis high, the outputs are in the high-impedance state.

To ensure the high-impedance state during power up or power down,OEshall be tied to VCCthrough a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
