1235 Walt Whitman Road, Melville, NY 11747 A3800 QUADRATURE CLOCK CONVERTER 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 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) o
