MC14580B
The MC14580B is a 4 by 4 multiport register useful in small scratch pad
memories, arithmetic operations when coupled with an adder, and other data
storage applications. It allows independent reading of any two words (or the
same word at both outputs) while writing into any one of four words.
Address changing and data entry occur on the rising edge of the clock.
When the write enable input is low, the contents of any word may be
accessed but not altered.
No Restrictions on Clock Input Rise or Fall Times
