SN74LVC245ADBR TI Bus Transceiver | 20-SSOP | 3.3V, 8-Bit, Non-Inverting

Product Overview

The SN74LVC245ADBR from Texas Instruments is a high-performance, 8-bit bus transceiver designed for 3.3-V VCC operation. It features non-inverting 3-state outputs and is ideal for asynchronous bidirectional communication between data buses. The device allows data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the direction-control (DIR) input. The output-enable (OE) input can be used to disable the outputs, effectively isolating the buses. The SN74LVC245ADBR is offered in a compact 20-pin SSOP package, making it suitable for space-constrained applications.
