SN74BCT244
SN74BCT244 is Octal Buffers/Drivers manufactured by Texas Instruments.
se octal buffers and line drivers are designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. Taken together with the ′BCT240 and ′BCT241, these devices provide the choice of selected binations of inverting and noninverting outputs, symmetrical OE (active-low output-enable) inputs, and plementary OE and OE inputs.
The ′BCT244 is organized as two 4-bit buffers/line drivers with separate output-enable (OE) inputs. When OE is low, the device passes data from the A inputs to the Y outputs. When OE is high, the outputs are in the high-impedance state.
The SN54BCT244 is characterized for operation over the full military temperature range of
- 55°C to 125°C. The SN74BCT244 is characterized for operation from 0°C to 70°C.
