Product Overview

The SN74ABT245BDW is an octal Bus Transceiver designed with 3-state outputs for asynchronous communication between data buses. The device transmits 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 pull-up resistor and 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. The IOFF 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.
  • IOFF and power-up 3-state support hot insertion
  • High-drive outputs
  • Latch-up performance exceeds 500mA per JEDEC standard JESD-17
  • Typical VOLP (output ground bounce) <1V at VCC = 5V, TA = 25°C
  • Green product and no Sb/Br
