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 I_OL, which facilitates switching 25- transmission lines on the incident wave. The distributed V_CC and GND pins minimize switching noise for more reliable system operation.

When the output-enable (1 and 2) inputs are low, the device transmits data from the A inputs to the Y outputs. When 1 and 2 are 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.
