... DESCRIPTION: The LS7083 and LS7084 are CMOS quadrature clock con- verters. Quadrature clocks derived from optical or magnetic encoders, when applied to the A and B inputs of the LS7083/ LS7084, are converted to strings of Up Clocks and Down Clocks (LS7083 Clock and an Up/Down direction control (LS7084). These outputs can be interfaced directly with standard Up/Down counters for direction and position sensing of the encoder ...
