MC74LVX157
Quad 2−Channel Multiplexer
With 5 V−Tolerant Inputs
The MC74LVX157 is an advanced high speed CMOS quad
2−channel multiplexer. The inputs tolerate voltages up to 7.0 V,
allowing the interface of 5.0 V systems to 3.0 V systems.
It consists of four 2−input digital multiplexers with common select
(S) and enable (E
) inputs. When E is held High, selection of data is
inhibited and all the outputs go Low.
The select decoding determines whether the I0 n or I1 n inputs get
routed to the corresponding Z n outputs.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.
