The SN74F382 is an arithmetic logic unit (ALU)/function generator that performs eight binary arithmetic/logic operations on two 4-bit words as shown in the function table. The exclusive-OR, AND, and OR functions of the two Boolean variables are provided without the use of external circuits. In addition, the outputs can be cleared (low) or preset (high) as desired. The device provides a ripple-carry (Cn+4) output to ripple the carry to the Cn input of the next stage. It detects and indicates the two's complement overflow condition via the overflow (OVR) output. OVR is logically equivalent to Cn+3 Cn+4. When the SN74F382 is cascaded to handle word lengths longer than four bits in length, only the most significant OVR is used. The SN74F382 is characterized for operation from 0C to 70C. FUNCTION TABLE |
