SN74ABT245BPWR

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. 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 |off and power - up 3 - state. The |0P circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down. The power - up 3 - state circuitry places the outputs in the high - impedance state during power up and power down, which prevents driver conflict.
