SN74FB2031RC TI Bus Switch | 52-QFP (10X10) | 3.3V, 5V Tolerant

Product Overview

The SN74FB2031RC is a high-performance 20-bit bus switch from Texas Instruments, designed for bidirectional voltage translation and signal isolation in mixed-voltage systems. It operates with a 3.3V supply while being 5V tolerant on I/O pins, making it ideal for interfacing between different logic families. Packaged in a compact 52-QFP (10x10mm), it offers low on-state resistance (5Ω typical) and minimal propagation delay, ensuring high-speed data transfer with minimal signal distortion.
