SN54LS381A

The SN54LS381A is low-power schottky and schottky TTL arithmetic logic units/function generators that perform eight binary arithmetic/logic operations on two 4-bit wprds as shown in the function table. The features of SN54LS381A are as follows: (1)full parallel 4-bit ALUs in 20-pin package for 0.300-inch row spacing; (2)ideally suited for high-density economical processors; (3)arithmetic and logic operations selected specially to simplify system implementation.

The absolute maximum ratings of the SN54LS381A are: (1)supply voltage, VCC: 7V; (2)input voltage: 7V; (3)operating free-air temperature range: -55 to 125; (4)storage temperature range: -65 to 150.
