Description

These SN54ABT245A octal bus transceivers are designed for asynchronous communication between data buses. The SN54ABT245A 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.

When VCC is between 0 and 2.1 V, the device is in the high-impedance state during power up or power down. However, to ensure the high impedance state above 2.1 V, 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.The SN54ABT245A is characterized for operation over the full military temperature range of 55 to 125. The SN74ABT245B is characterized for operation from 40 to 85.
