FEATURES
DESCRIPTION
The 74F524 is an 8-bit bidirectional register with parallel input and
output, plus serial input and output progressing from MSB to LSB.
All data inputs, serial and parallel, are loaded by the rising edge of
the clock. The device functions are controlled by two control lines
(S0, S1) to execute shift, load, hold and read out. An 8-bit
comparator examines the data stored in the registers and on the
data bus. Three true-High, open collector outputs representing
‘register equal to bus’, ‘register greater than bus’ and ‘register less
than bus’ are provided. These outputs can be disabled to the OFF
state by the use of Status Enable (SE). A mode control has also
been provided to allow Two’s Complement as well as magnitude
compare. Linking inputs are provided for expansion to longer words.
INPUT AND OUTPUT LOADING AND FAN-OUT TABLE
NOTE:
One (1.0) FAST Unit Load (U.L.) is defined as 20 A in the High state and 0.6mA in the Low state.
