SN74CB3T3245DGSR TI Bus Switch | 20-VSSOP | 8-Bit, 2.3-3.6V

Product Overview

The SN74CB3T3245DGSR is a high-performance 8-bit bus switch from Texas Instruments, designed for voltage translation and signal isolation in mixed-voltage systems. Housed in a compact 20-VSSOP package, it features a low on-state resistance (5 Ω typical) and supports bidirectional data flow with minimal propagation delay. The device operates over a wide supply voltage range of 2.3 V to 3.6 V, making it ideal for interfacing between different logic levels. Its flow-through pinout simplifies PCB layout, and the integrated Ioff protection ensures the switch remains in a high-impedance state when power is off, preventing back-drive current.

Detailed Technical Specifications

Key Features
