8-Bit FET 2.5-V/3.3-V Low-Voltage Bus Switch With 5-V Tolerant Level Shifter - SN74CB3T3245

SN74CB3T3245 (ACTIVE)

8-Bit FET 2.5-V/3.3-V Low-Voltage Bus Switch With 5-V Tolerant Level Shifter

 

Description

The SN74CB3T3245 device is a high-speed TTL-compatible 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.

For all available packages, see the orderable addendum at the end of the data sheet.
