MC74LVX257
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.
