description/ordering information

These octal bus transceivers are designed for asynchronous communication between data buses. The devices

transmit data 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 be used to disable the device so the buses are

effectively isolated.

SN54ABT245A, SN74ABT245B OCTAL BUS TRANSCEIVERS WITH 3-STATE OUTPUTS SCBS081L − JANUARY 1991 − REVISED APRIL 2005 description/ordering information (continued) To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. This device is fully specified for hot-insertion applications using Ioff and power-up 3-state.
