SN74LVC646ADBR TI Bus Transceiver | 24-SSOP | 3.3V, 8-Bit, Non-Inverting

Product Overview

The SN74LVC646ADBR is a high-performance 8-bit bus transceiver from Texas Instruments, 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 disable the outputs, effectively isolating the buses. The SN74LVC646ADBR is housed in a compact 24-SSOP package, making it suitable for space-constrained applications.
