LS7566R-TS

Counter Dividers Overview

The LS7566R-TS is a quadrature counter component manufactured by LSI Computer Systems, housed in a TSSOP package. It integrates four identical modules of 24-bit programmable counters designed for direct interface with incremental encoders. The device supports operation as quadrature clock counters or non-quadrature up/down counters. It features a 3-state Octal I/O bus and operates within a voltage range of 3V to 5.5V. Count frequencies reach 40 MHz at 5V and 20 MHz at 3V.

Counter Dividers Feature Summary

• Configurable count modes including free-running, non-recycle, modulo-n, and range-limit operations.
• Digital filtering of input quadrature clocks to ensure noise immunity.
• Separate mode-control registers provided for each axis.

Counter Dividers Applications

• Direct interface with incremental encoders
• Quadrature clock counting applications
• Non-quadrature up/down counting systems

Counter Dividers Procurement Notes

Verify the manufacturer designation carefully, as sources list both LSI Computer Systems and LSI. Confirm the specific suffix 'TS' corresponds to the TSSOP package type. Ensure the part number matches the exact revision required for your design specifications.

Counter Dividers Selection Notes

Select this component when a multi-axis encoder interface is required. It provides integrated digital filtering for noise reduction. Verify that the operating voltage aligns with the 3V to 5.5V specification. Check if the 24-bit resolution meets the position tracking requirements.

Counter Dividers Part Context

This component belongs to the LS7566 family of quadrature counters. Variants such as LS7566R share similar functional descriptions. The family is designed for high-speed counting applications requiring multiple independent axes.
