DESCRIPTION/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).
