SN74LVC257APWR TI Signal Switches, Multiplexers, Decoders

The SN74LVC257A is a quad 2-input multiplexer with 3-state outputs, selecting one of two data inputs for each of four outputs. It operates from 1.65V to 3.6V and features 5V-tolerant inputs. The device includes a common select input and an output enable that forces outputs into high-impedance state. Propagation delay is 3.6ns typical at 3.3V. Selection is ideal for data routing in low-voltage systems. Applications include data source selection in microprocessor systems, bus switching, memory banking, and signal routing in telecommunications and computing equipment requiring quad 2:1 multiplexing with 3-state outputs.
