description
The SN64BCT25245 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 (OE) input can disable the device so that
both buses are effectively isolated.
This transceiver is 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.
The outputs are in a high-impedance state during power up and power down while the supply voltage is less
than approximately 3 V.
The SN64BCT25245 is characterized for operation from –40
°
C to 85
°
C and 0

C to 70
