SN64BCT25244 具有三态输出的八路缓冲器/驱动器
SN64BCT25244 描述
The SN64BCT25244 is a 25-Ω octal buffer and line driver designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented transceivers.
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.
This buffer/driver is 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.
The outputs are in a high-impedance state during power up and power down while the supply voltage value is less than approximately 3 V
