The SMD SN74HC85 is a 4-bit magnitude comparator IC in SOP-16 (SOIC-16) surface-mount package, designed for digital comparison and arithmetic logic applications in Pakistan. This CMOS logic integrated circuit compares two 4-bit binary or BCD numbers and provides three outputs indicating whether A is greater than, equal to, or less than B. Perfect for digital systems requiring number comparison, sorting algorithms, and control logic applications.
