SN74CBT6845CDBQR TI Bus Switch | 20-SSOP | 8-Bit, 5V, 250MHz

Product Overview

The SN74CBT6845CDBQR from Texas Instruments is a high-performance 8-bit bus switch designed for bidirectional voltage translation and signal isolation. Housed in a compact 20-SSOP package, this device features low on-state resistance (5 Ω typical) and wide bandwidth (250 MHz), making it ideal for hot-swap and bus isolation applications in computing, telecom, and industrial systems. It operates over a broad supply voltage range of 4.5 V to 5.5 V and supports both 5V and 3.3V signal levels, ensuring compatibility with mixed-voltage environments.
