description

These octal buffers/drivers are designed specifically to improve the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters.

The 'ACT244 are organized as two 4-bit buffers/drivers with separate output-enable () inputs. When is low, the device passes noninverted data from the A inputs to the Y outputs. When is high, the outputs are in the high-impedance state.

The SN54ACT244 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ACT244 is characterized for operation from -40°C to 85°C.
