The LFLS7183 allow incremental encoders to drive standard up/down counters. Connect the encoder quadrature outputs to the A & B inputs. The LFLS7183 outputs can connect directly to the up and down clock inputs of counters such as 74193 or 40193. The LFLS7183 is an improved version of the LS7083 and should be considered first for all new product designs. The primary differences between the old and new LS chips are the addition of a x2 resolution multiplication, power supply operating range and improved output pulse timing characteristics.

Please note: Rbias values for output pulse width timing are not the same as the LS7083.
