SN74CBT3345DBLE TI Bus Switch | 8-bit | 5V Tolerant, Low On-Resistance

Product Overview

The SN74CBT3345DBLE from Texas Instruments is a high-performance 8-bit bus switch designed for bidirectional voltage translation and signal isolation. It features a low on-state resistance of typically 5 ohms, ensuring minimal signal distortion. The device operates over a wide voltage range from 4.5V to 5.5V and is compatible with TTL logic levels. Its flow-through pinout simplifies PCB layout, making it ideal for bus isolation and multiplexing applications in computing, telecommunications, and industrial systems.
