SN74CBT3345CDBR TI Bus Switch | 20-SSOP | 5V, 8-Bit, 3-State

Product Overview

The SN74CBT3345CDBR from Texas Instruments is a high-performance 8-bit bus switch designed for bidirectional voltage translation and signal isolation. Housed in a compact 20-pin SSOP package, this device features low on-state resistance (5 Ω typical) and wide supply voltage range (4.5 V to 5.5 V), making it ideal for hot-swap and bus isolation applications. The 3-state outputs allow connection to a common data bus without adding propagation delay or loading effects.
