SN74BCT25244 描述These 25-Ω 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-Ω transmission lines on the incident wave. The distributed VCC 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
