The SN74LVC245ADBR is an octal Bus Transceiver with 3-state outputs and designed for 1.65 to 3.6V VCC operation. This device is designed for asynchronous communication between data buses. This 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 input. The output-enable input can be used to disable the device so the buses effectively are isolated. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pull-up resistor, the minimum value of the resistor is determined by the current-sinking capability of the driver. Inputs can be driven from either 3.3/5V devices. This feature allows the use of this device as a translator in a mixed 3.3/5V system environment. This device is fully specified for partial-power-down applications using IOFF. The IOFF circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
The SN74LVC245APWR is an Octal Bus Transceiver with 3-state outputs. This octal bus transceiver is designed for 1.65 to 3.6V VCC operation. The SN74LVC245APWR device is designed for asynchronous communication between data buses. ESD protection exceeds JESD 22, 2000V human-body model and 1000V charged-device model.
