LS7166A-TS

Counter Dividers Overview

The LS7166A-TS is a CMOS, 24-bit quadrature counter manufactured by LSI Computer Systems. It operates within a voltage range of 3V to 5.5V and supports count frequencies from DC to 25MHz. The device features an 8-bit I/O bus for microprocessor communication and includes programmable modes such as Up/Down, Binary, BCD, Divide-by-N, and x1/x2/x4 Quadrature. It utilizes a 24-pin TSSOP package.

Counter Dividers Feature Summary

• Programmable operational modes including quadrature counting and binary counters
• Integrated 24-bit comparator for preset count comparison
• Compatible with TTL and CMOS logic levels
• Includes readable output status register for instantaneous hardware control

Counter Dividers Applications

• Position sensing systems
• Speed measurement circuits
• Motor control applications

Counter Dividers Procurement Notes

Verify the specific suffix 'TS' corresponds to the 24-pin TSSOP package configuration. Confirm manufacturer lineage as LSI Computer Systems or acquired entities like Microsemi. Ensure compatibility with required operating voltage and interface standards before integration.

Counter Dividers Selection Notes

Select this component when a dedicated 24-bit counter with quadrature decoding is required. It is suitable for designs needing direct microprocessor interfacing via an 8-bit bus. Consider the TSSOP package constraints for PCB layout and thermal management in compact assemblies.

Counter Dividers Part Context

The LS7166 series serves as a specialized digital counter solution for industrial and consumer electronics. The A variant typically denotes enhanced specifications or revisions within the family. The TS suffix identifies the specific surface-mount plastic small-outline package type used for board mounting.

Counter Dividers Replacement Considerations

Check for availability of LS7166-S (SOIC) or LS7166 (DIP) if package form factor changes are permissible. Verify functional equivalence with other 24-bit quadrature counters from manufacturers like Texas Instruments or Analog Devices if sourcing is restricted.
