Introduction

The LS7083N and LS7084N are CMOS quadrature clock converters. Quadrature clocks derived from optical or magnetic encoders, when applied to the A and B inputs of the LS7083N or LS7084N, are converted to strings of Up Clocks and Down Clocks (LS7083N) or to a Clock and an Up/Down direction control (LS7084N). These outputs can be interfaced directly with standard Up/Down counters for direction and position sensing of the encoder.

Features

• x1 and x4 mode selection
• Up to 16MHz output clock frequency
• Programmable output clock pulse width
• On-chip filtering of inputs for optical or magnetic encoder applications
• TTL and CMOS compatible I/Os
• +3V to +12V operation (VDD - VSS)

Applications

• Interface incremental encoders to Up / Down Counters
• Interface rotary encoders to Digital Potentiometers
