DESCRIPTION
: The LS7183 and LS7184 are monolithic CMOS silicon gate quadrature clock converters. Quadrature clocks derived from optical or magnetic encoders, when applied to the A and B inputs of the LS7183/LS7184, are converted to strings of Up Clocks and Down Clocks (LS7183) or to a Clock and an Up/ Down direction control (LS7184). These outputs can be interfaced directly with standard Up/Down counters for direction and position sensing of the encoder. INPUT/OUTPUTDESCRIPTION
: RBIAS (Pin 1) Input for external component connection. A resistor connected between this input and VSS adjusts the output clock pulse width (Tow). VDD (Pin 2) Supply Voltage positive terminal. VSS (Pin 3) Supply Voltage negative terminal. A, B (Pin 4, Pin 5) Quadrature Clock inputs A and B.
