LS7366R-TS

Counter Dividers Overview

The LS7366R-TS is a 32-bit CMOS quadrature counter featuring a serial interface, designed for direct connection to incremental encoders. It operates within a voltage range of 3V to 5.5V and supports count frequencies up to 40MHz at 5V or 20MHz at 3V. The device includes a 32-bit counter, data register, comparator, and output register, alongside programmable mode registers. It offers x1, x2, or x4 quadrature counting modes and non-quadrature up/down counting. The component is housed in a TSSOP package.

Counter Dividers Feature Summary

• Supports quadrature clock decoding with internal filtering for incremental encoder interfaces
• Provides programmable counting modes including modulo-N, range-limit, and free-running operations
• Features an index-driven mechanism for counter load, output register load, or reset functions
• Includes latched interrupt outputs triggered by carry, borrow, compare, or index events

Counter Dividers Applications

• Position tracking systems using incremental encoders
• Motor control applications requiring precise speed and direction monitoring
• Industrial automation equipment utilizing quadrature signals
• Marker function implementation in motion control setups

Counter Dividers Procurement Notes

Verify the specific suffix 'TS' corresponds to the TSSOP package variant when ordering. Confirm the manufacturer designation as LSI Computer Systems or CSI to ensure component authenticity. Check RoHS compliance status and moisture sensitivity level requirements prior to assembly planning. Ensure the serial interface configuration matches your system's SPI or Microwire protocol constraints.

Counter Dividers Selection Notes

Select this component when a 32-bit resolution counter with serial interface is required for quadrature encoding applications. Consider the operating voltage range and maximum count frequency relative to your encoder specifications. Evaluate the need for specific counting modes such as modulo-N or range-limiting against your application logic. Verify that the TSSOP package form factor fits your PCB layout constraints.

Counter Dividers Part Context

The LS7366R series comprises 32-bit quadrature counters available in multiple package options. The base model LS7366R is offered in DIP and SOIC packages, while the -TS suffix specifically denotes the Thin-Shrink Small-Outline Package (TSSOP). This family provides flexible configuration through mode registers and supports both quadrature and standard up/down counting methods for various industrial and consumer applications.

Counter Dividers Replacement Considerations

Direct substitutes include LS7366R in DIP or SOIC packages if pin compatibility allows. Verify functional equivalence regarding serial interface protocols and counting capabilities before substitution.
