The LS7183N and LS7184N are CMOS quadrature clock converters. Quadrature clocks derived from optical or magnetic encoders, when applied to the A and B inputs of the LS7183N / LS7184N, are converted to strings of Up Clocks and Down Clocks (LS7183N) or to a Clock and an Up/Down direction control (LS7184N). These outputs can be interfaced directly with standard Up/Down counters for direction and position sensing of the encoder.
