These SN74LV245A octal bus transceivers are designed for 2-V to 5.5-V VCC operation.
The SN74LV245A devices are designed 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, SN74LV245A 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 SN54LV245A is characterized for operation over the full military temperature range of 55 to 125. The SN74LV245A is characterized for operation from 40 to 85.
