SN74CB3T3245 Description
The SN74CB3T3245 device is a high-speed TTLpatible 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. SN74CB3T3245 SCDS136C OCTOBER 2003 REVISED MAY 2018 .ti.
