SN74CBT3345PW TI Bus Switch | 20-TSSOP | 5V, 8-Bit, 250MHz

Product Overview

The SN74CBT3345PW from Texas Instruments is a high-performance 8-bit bus switch designed for bidirectional voltage translation and signal isolation. Housed in a compact 20-TSSOP package, it operates over a wide supply voltage range of 4.5V to 5.5V, making it ideal for 5V systems. With a typical propagation delay of 250 ps and support for data rates up to 250 MHz, this device ensures minimal signal distortion in high-speed digital applications. The SN74CBT3345PW features low ON-state resistance (5 Ω typical) and low power consumption, enabling efficient bus isolation and multiplexing.
