LS7267

Counter Dividers Overview

The LS7267 is a dual 24-bit multi-mode counter IC designed for motion control applications. It supports X and Y axes with quadrature, BCD, and binary counting modes. The device features two independent counting elements with positive edge triggering and a maximum count rate of 50 MHz. It operates on a supply voltage range of 3 V to 5.5 V and includes an 8-bit I/O bus along with dual 24-bit comparators.

• Industrial automation equipment
• Robotics joint control modules

Counter Dividers Procurement Notes

Verify the specific package variant (SOIC or TSSOP) and suffix (e.g., -S, -TS) against the required pinout and thermal specifications. Confirm RoHS compliance status if environmental regulations apply. Ensure the operating voltage range matches the system power supply. Check for lead-free manufacturing requirements in the datasheet before finalizing procurement.

Counter Dividers Selection Notes

Select this component when dual-axis quadrature decoding is required in a single package. The 50 MHz count rate suits high-speed applications. Choose between SOIC and TSSOP packages based on board space constraints. Verify that the 8-bit I/O bus width meets the microcontroller interface requirements. Consider the 3 V to 5.5 V supply range for compatibility with various logic families.

Counter Dividers Part Context

LSI Computer Systems developed the LS7267 as a specialized counter for precision motion control. It integrates dual 24-bit counters to handle complex positioning tasks. The device simplifies design by combining counting, comparison, and mode selection functions. It serves as a dedicated solution for incremental encoder interfaces in industrial machinery.

Counter Dividers Replacement Considerations

No direct public substitute part numbers are confirmed for the LS7267. Evaluate alternative dual-axis counters from other manufacturers only if they match the 24-bit resolution, quadrature support, and package dimensions. Verify electrical compatibility before substitution.
