DESCRIPTION/ORDERING INFORMATION

The SN74CB3T3245 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 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).

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
