The 74HC158 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.
When E 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 bu...
