SN74LVC646APW TI Bus Transceiver | 24-TSSOP | 3.3V, 8-Bit

Product Overview

The SN74LVC646APW is a high-performance 8-bit bus transceiver and register from Texas Instruments, designed for 3.3-V VCC operation. It features dual 8-bit D-type flip-flops with 3-state outputs, providing bidirectional data flow between two buses (A and B). The device is ideal for asynchronous communication between data buses, with direction control (DIR) and output enable (OE) inputs. Packaged in a compact 24-TSSOP, it offers low power consumption and high drive capability, making it suitable for a wide range of digital systems.
