Description

   The SN74CB3T16211 is a high-speed TTL-compatible FET bus switch with low ON-state resistance (r_on), 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 V_CC. The SN74CB3T16211 supports systems using 5-V TTL,3.3-V LVTTL, and 2.5-V CMOS switching standards, as well as user-defined switching levels
