74x Series Chip Resistor Arrays
The 74x Series Chip Arrays are single packaged devices containing an array of homogeneous resistor elements, designed for convenience when multiple resistors occupy the same layout area. These arrays offer advantages such as low cost thick film technology, leadless surface mount construction, and improved TCR tracking compared to discrete resistors. They reduce placement costs by minimizing component count. Available in isolated and bussed circuit configurations with concave or convex terminations and solder coated nickel barrier pads, these arrays are suitable for various applications including data communications, image processing, medical equipment, networking, pull-up/pull-down logic gates, DDR SDRAM, MDDR, DRAM, portable test equipment, and low-profile high-density designs.
