SN74LVC4245APWR

The SN74LVC4245APWR is a non-inverting Octal Bus Transceiver and 3.3 to 5V Shifter with 3-state outputs. The SN74LVC4245A device is 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 input can be used to disable the device so the buses are effectively isolated. The control circuitry is powered by VCCA. The SN74LVC4245A device terminal out allows the designer to switch to a normal all 3.3 or all 5V 20-terminal SN74LVC4245 device without board re-layout. The designer uses the data paths for pins 2-11 and 14-23 of the SN74LVC4245A device to align with the conventional 245 terminal out.

警告

This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
