description/ordering informationThe SN74CBT3257 is a 4-bit 1-of-2 high-speed TTL-compatible FET multiplexer/demultiplexer. The low
on-state resistance of the switch allows connections to be made with minimal propagation delay.
Output-enable (OE) and select-control (S) inputs select the appropriate B1 and B2 outputs for the A-input data.
ORDERING INFORMATION Package drawings, standard packing quantities, thermal data, symbolization, and PCB design
guidelines are available at www.ti.com/sc/package.
FUNCTION TABLEPlease 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.
