Texas Instruments SN74LV245A Octal Bus Transceivers are designed for asynchronous two-way communication between data buses. These parts operate from 2 to 5.5V VCC operation. The control-function implementation minimizes external timing requirements. The Texas Instruments SN74LVT245A devices allow 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 be used to disable the device so that the buses are effectively isolated.


  • 2V to 5.5V VCC operation
  • Maximum tpd of 6.5ns at 5V
  • Typical VOLP (output ground bounce) < 0.8V at VCC = 3.3V, TA = 25°C
  • Typical VOHV (output VOH undershoot) > 2.3V at VCC = 3.3V, TA = 25°C
  • Support mixed-mode voltage operation on all ports
  • Ioff supports partial-power-down mode operation
  • Latch-up performance exceeds 250mA per JESD 17
  • ESD protection exceeds JESD 22
