SN74FB2031RCG3 TI Bus Switch | 52-QFP (10x10) | 3.3V, 5V Tolerant

Product Overview

The SN74FB2031RCG3 is a high-performance 20-bit bus switch from Texas Instruments, designed for bidirectional voltage translation and signal isolation in mixed-voltage systems. Housed in a compact 52-pin QFP package (10x10 mm), it operates over a wide supply voltage range of 3.0V to 3.6V with 5V tolerant I/Os, making it ideal for interfacing between 3.3V and 5V logic families. The device features low on-state resistance (5 Ω typical) and minimal propagation delay (0.25 ns), ensuring high-speed signal integrity.
