说明
The ´BCT25245 is a 25-
octal bus transceiver designed for asynchronous communication between data buses. It improves both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented transceivers.
The device allows data transmission from the A bus to the B bus or from the B bus to the A bus depending upon the logic level at the direction-control (DIR) input. The output-enable (
) input can disable the device so that both buses are effectively isolated.
These transceivers are capable of sinking 188-mA IOL, which facilitates switching 25-
transmission lines on the incident wave. The distributed VCC and GND pins minimize switching noise for more reliable system operation.
