10 piece minimum order.
These IC Chips are a CMOS quadrature clock converter. Quadrature clocks derived from optical or magnetic encoders, when applied to A and B inputs are converted to strings of Up Clocks and Down Clocks. Pulses derived from the Index Track of an encoder, when applied to the INDX input, produce absolute position reference pulses which are synchronized to the Up Clocks and Down Clocks. These outputs can be interfaced directly with standard Up/Down counters for direction and position sensing of the encoder.

LSI-LS7366R is a 32-bit CMOS counter, with direct interface for quadrature clocks from incremental encoders. It also interfaces with the index signals from incremental encoders to perform variety of marker functions.
The LSI-LS7166 is a CMOS, 24-bit counter that can be programmed to operate in several different modes. The operating mode is set up by writing control words into internal control registers
