74x Series Chip Resistor Arrays
The 74x Series Chip Arrays are single packaged devices containing an array of homogeneous resistor elements. These arrays are designed for convenience when multiple resistors occupy the same area in a layout. They offer advantages such as low cost thick film technology, leadless surface mount construction, and improved TCR tracking compared to discrete resistors. By reducing component count, these arrays help save placement costs in high-density designs.
