Quad 2-Channel Multiplexer with 3-State Outputs

The MC74LVX257 is an advanced high speed CMOS quad 2−channel multiplexer fabricated with silicon gate CMOS technology.

It consists of four 2−input digital multiplexers with common select (S) and enable (OE) inputs. When (OE) is held High, selection of data is inhibited and all the outputs go Low.

The select decoding determines whether the A or B inputs get routed to the corresponding Y outputs.

The inputs tolerate voltages up to 7.0 V, allowing the interface of 5.0 V systems to 3.0 V systems.
