74F524 8-Bit Registered Comparator
April 1988
Revised August 1999
74F524
8-Bit Registered Comparator
General Description
The 74F524 is an 8-bit bidirectional register with parallel
input and output plus serial input and output progressing
from LSB to MSB. All data inputs, serial and parallel, are
loaded by the rising edge of the input clock. The device
functions are controlled by two control lines (S
0
, S
1
) to exe-
cute shift, load, hold and read out.
An 8-bit comparator examines the data stored in the regis-
ters and on the data bus. Three true-HIGH, open-collector
outputs representing 鈥渞egister equal to bus鈥? 鈥渞egister
greater than bus鈥?and 鈥渞egister less than bus鈥?are provided.
These outputs can be disabled to the OFF state by the use
of Status Enable (SE). A mode control has also been pro-
vided to allow twos complement as well as magnitude com-
pare. Linking inputs are provided for expansion to longer
words.
