Product Summary
The SN74CBTLV3257DR is a low-voltage 24-bit FET bus-exchange switch. It provides 24 bits of high-speed bus switching or exchanging. The low on-state resistance of the switch allows connections to be made with minimal propagation delay. The SN74CBTLV3257DR operates as a 24-bit bus switch or a 12-bit bus exchanger, which provides data exchanging between the four signal ports via the data-select (S0, S1, S2) terminals. It is specified by the break-before-make feature to have no through current when switching between B ports. The SN74CBTLV3257DR is characterized for operation from –40 to 85℃.
