LS7184 Overview
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...

- DNCK (Pin 7) In LS7183, this is the DOWN Clock Output. This output consists of low-going pulses generated when A input l
- UP/DN (Pin 7) In LS7184, this is the count direction indication output. When A input leads the B input, the UP/DN output
- UPCK (Pin 8) In LS7083LV, this is the UP Clock output. This output consists of low-going pulses generated when A input l
