description

The SN74CBT3251 is an 8-bit to 1-bit high-speed TTL-compatible FET multiplexer/ demultiplexer. The low on-state resistance of the switch allows connections to be made with minimal propagation delay.

When output enable () is low, the SN74CBT3251 is enabled. S0, S1, and S2 select one of the B outputs for the A-input data.

The SN74CBT3251 is available in TI's shrink small-outline (DB) and thin shrink small-outline (PW) packages, which provide the same I/O pin count and functionality of standard small-outline packages in less than half the printed-circuit-board area.

The SN74CBT3251 is characterized for operation from -40°C to 85°C.
