description

The SN74CBT3257 is a quadruple 2-bit to 1-bit high-speed TTL-compatible FET demultiplexer/ multiplexer. The low on-state resistance of the switch allows connections to be made with minimal propagation delay.

Output-enable () and select-control (S) select the appropriate B1 and B2 outputs for the A-input data.

The SN74CBT3257 is characterized for operation from –40°C to 85°C.
