25-W OCTAL BUS TRANSCEIVERS WITH 3-STATE OUTPUTS

The ABTH25245 are 25- octal Bus Transceivers designed for asynchronous Communication between data buses. They improve both the performance and density of 3-state memory address drivers, Clock Drivers and bus-oriented transceivers. These devices allow noninverted data transmission from the A bus to the B bus or from the B bus to the A bus, depending on 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. When OE is low, the device is active. These transceivers are capable of sinking 188 mA of IOL current, which facilitates switching 25- transmission lines on the incident wave. The distributed VCC and GND pins minimize switching noise for more-reliable system operation. By Texas Instruments
