LS7084-P DIP8 (LSI) QUADRATURE CLOCK CONVERTER

The LS7083 and LS7084 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 LS7083/LS7084, are converted to strings of Up Clocks and Down Clocks (LS7083) or to a 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.

• On-chip filtering of inputs for optical or magnetic encoder applications.

• TTL and CMOS compatible I/Os

• +4.75V to +10.5V operation (VDD-VSS)

• 8-Pin DIP (SOIC available)
