Description
SN74LVC4245ADWRTexas Instruments Octal Bus Transceiver And 3.3-V To 5-V Shifter With 3-State Outputs RoHS
This 8-bit (octal) noninverting bus transceiver contains two separate supply rails; B port has VCCB, which is set at 3.3 V, and A port has VCCA, which is set at 5 V. This allows for translation from a 3.3-V to a 5-V environment, and vice versa.

MFG Part #: SN74LVC4245ADWR
The SN74LVC4245ADWR is a 8-bit (octal) Non-inverting Bus Transceiver contains two separate supply rails, B port has VCCB, which is set at 3.3V and A port has VCCA, which is set at 5V. This allows for translation from a 3.3 to a 5V environment and vice versa. The SN74LVC4245ADWR 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 (OE) input can be used to disable the device so the buses are effectively isolated. The control circuitry (DIR, OE) is powered by VCCA. The SN74LVC4245ADWR device terminal out allows the designer to switch to a normal all-3.3V or all-5V 20-terminal SN74LVC4245ADWR device without board re-layout. The designer uses the data paths for pins 2-11 and 14-23 of the SN74LVC4245ADWR device to align with the conventional ‘245 terminal out.
