Quad 2-input multiplexer; inverting
General descriptionThe 74HC is a high-speed Si-gate CMOS device and is pin compatible with low power
Schottky TTL (LSTTL). The 74HC158 is speciﬁed in compliance with JEDEC
standard no. 7A.
The 74HC158 is a quad 2-input multiplexer which select 4 bits of data from two sources
and are controlled by a common data select input (S). The four outputs present the
selected data in the inverted form. The enable input (E) is active LOW.
WhenE is HIGH, all the outputs (1Y to 4Y) are forced HIGH regardless of all other input
conditions.
Moving the data from two groups of registers to four common output buses is a common
useof the 74HC158. The stateofS determines the particular register from which the data
comes. It can also be used as a function generator.
The device is useful for implementing highly irregular logic by generating any four of the
16 different functions of two variables with one variable common.
The 74HC158is the logic implementationofa 4-pole, 2-position switch, where the position
of the switch is determined by the logic levels applied to S.
The logic equations for the output are:
1Y = E.(1l1.S+ 1l0.S)
2Y = E.(2l1.S+ 2l0.S)
3Y = E.(3l1.S+ 3l0.S)
4Y = E.(4l1.S+ 4l0.S)
The 74HC158 is identical to the 74HC157 but has inverting outputs. Features Low-power dissipation Inverting data path Complies with JEDEC standard no. 7A ESD protection: HBM EIA/JESD22-A114-B exceeds 2000V MM EIA/JESD22-A115-A exceeds 200V. Multiple package options Speciﬁed from −40 °Cto+80 °C and from −40°Cto +125 °C.
