DESCRIPTION:
The LS7183 and LS7184 are CMOS 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

FEATURES:
• x1, x2 and x4 resolution
• Programmable output pulse width (200ns to 140µs)
• Excellent regulation of output pulse width
• TTL and low voltage CMOS compatible I/Os
• +3V to +5.5V operation (VDD - VSS)
• LS7183, LS7184 (DIP);
   LS7183-S, LS7184-S (SOIC) - See Figure 1

APPLICATIONs:
• Interface incremental encoders to Up / Down Counters
   (See Figure 6A and Figure 6B)
• Interface rotary encoders to Digital Potentiometers
   (See Figure 7)
