Overview: Product Folder Order Now Technical Documents Tools & Software Support & Community SN74CB3T3245 SCDS136C – OCTOBER 2003 – REVISED MAY 2018 SN74CB3T3245 8-Bit FET Bus Switch 2.5-V and 3.

General Description

The SN74CB3T3245 device is a high-speed TTLcompatible 8-bit FET bus switch with low ON-state resistance (ron), allowing for minimal propagation delay.

The device fully supports mixed-mode signal operation on all data I/O ports by providing voltage translation that tracks VCC.
