Description

These 25-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. These buffers are capable of sinking 188-mA IOL, which facilitates switching 25-transmission lines on the incident wave. The distributed VCCand GND pins minimize switching noise for more reliable system operation. When the output-enable (1and 2) inputs are low, the device transmits data from the A inputs to the Y outputs. When 1and 2are high, the outputs are in the high-impedance state. The SN54BCT25244 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74BCT25244 is characterized for operation from 0°C to 70°C.
