8-bit Fet 2.5-v/3.3-v Low-voltage Bus Switch With 5-v Tolerant Level Shifter

  /ORDERING INFORMATION The SN74CB3T3245 is a high-speed TTL-compatible 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. The SN74CB3T3245 supports systems using 5-V TTL, 3.3-V LVTTL, and 2.5-V CMOS switching standards, as well as user-defined switching levels (see Figure 1).
