description

The ′BCT25245 is a 25-Ω 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.

These transceivers are 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 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.
