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, offering advantages such as reduced placement costs through a lower component count compared to discrete resistors. They feature low-cost thick film technology, leadless surface mount construction with concave or convex terminations, and solder-coated nickel barrier pads. Available in isolated and bussed circuit configurations, these arrays provide improved TCR tracking over discrete resistors and are supplied in tape and reel packaging.
Applications: Data Communications, Image Processing, Medical Equipment, Networking, Pull-Up/Pull-Down Logic Gates, DDR SDRAM, MDDR, DRAM, Portable Test Equipment, Low Profile High Density Designs.
