SN74LVT543DW TI Bus Transceiver | 24-SOIC | 3.3V, 8-Bit

Product Overview

The SN74LVT543DW is an 8-bit registered transceiver from Texas Instruments, designed for 3.3-V VCC operation with 5-V tolerant I/Os. It features D-type flip-flops with 3-state outputs, providing bidirectional data flow between two buses (A and B). The device is ideal for driving high-capacitance loads and supports live insertion and withdrawal (hot swap) due to its power-up 3-state circuitry. Packaged in a 24-pin SOIC (DW) package, it offers a compact solution for bus interface applications.
