Description

General part information

SN74ACT244-EP Series

The SN74ACT244-EP octal buffer/driver is designed specifically to improve the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters.

The device is organized as two 4-bit buffers/drivers with separate output-enable (OE) inputs. WhenOEis low, the device passes noninverted 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,OEshould be tied to VCCthrough a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
