74LVCH245A
Description
The 74LVCH245A is an octal transceiver designed for asynchronous munication 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) pin can be used to disable the device so the buses effectively are isolated.
The device is designed for operation with a power supply range of 1.65V to 3.6V.
The inputs are tolerant to 5.5V allowing this device to be used in a mixed voltage environment. The device is fully specified for partial power down applications using IOFF. The IOFF circuitry disables the output preventing damaging current backflow when the device is powered down.
Pin Assignments
Bus hold circuitry holds unused or undriven inputs at a high or low logic state. The use of external pull-up or pull down resistors is not remended.
