description

The SN64BCT25245 is a 25-octal bus transceiver designed for asynchronous communication betweendata buses. It improves both the performance and density of 3-statememory address drivers, clock drivers, and bus-oriented transceivers.

The device allows data transmission from the A bus to the B bus orfrom the B bus to the A bus depending upon the logic level at thedirection-control (DIR) input. The output-enable () input can disable the device sothat 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. Thedistributed V_CC and GND pins minimize switching noise formore reliable system operation.

The outputs are in a high-impedance state during power up andpower down while the supply voltage is less than approximately 3 V.

The SN64BCT25245 is characterized for operation from -40°C to85°C and 0°C to 70°C.
