MC54/74F382
4-BIT ARITHMETIC LOGIC UNIT
The MC54/74F382 performs three arithmetic and three logic operations on
two 4-bit words, A and B. Two additional Select input codes force the Function
outputsLOWorHIGH. AnOverflowoutputisprovidedforconvenienceintwos
complement arithmetic. A Carry output is provided for ripple expansion. For
high-speed expansion using a Carry Lookahead Generator, refer to the F381
data sheet.

NOTES:
1. For conditions such as MIN or MAX, use the appropriate value specified under guaranteed operating ranges.
2. Not more than one output should be shorted at a time, nor for more than 1 second.
FUNCTIONAL DESCRIPTION
Signals applied to the Select inputs S –S determine the
LOW for active LOW operands) into the C input of the least

mode of operation, as indicated in the Function Select Table.
An extensive listing of input and output levels is shown in the
Truth Table. The circuit performs the arithmetic functions for
either active HIGH or active LOW operands, with output levels
in the same convention. In the Subtract operating modes, it is
necessary to force a carry (HIGH for active HIGH operands,
significant package. Ripple expansion is illustrated in Figure
1. The overflow output OVR is the Exclusive-OR of C
and
; a HIGH signal on OVR indicates overflow in twos

in Figure 2.
