SN54BCT25245 improves both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented transceivers.
The SN54BCT25245 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 SN54BCT25245 so that both buses are effectively isolated.
These transceivers of SN54BCT25245 are 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 SN54BCT25245 is characterized for operation over the full military temperature range of 55°C to 125°C. The SN74BCT25245 is characterized for operation from 0°C to 70°C.
