The SN74AVC4T245PWR is a 4-bit, dual-supply bus transceiver manufactured by Texas Instruments. It is designed to operate from either supply, with inputs and outputs at the same voltage, and interfaces inputs to outputs with TTL level compatible logic levels. The transceiver devices have three enable controls (one active-high and two active-low) that allow for the creation of various combinations of data flow and direction control. Outputs can be disabled to minimize power consumption. The device has an operating voltage of 2.0 to 3.6V, with flow-through pinout for ease of board layout. The device includes two separate configurable Pull-Up regions that allow for enabling or forcing outputs to a known state.
