Description
The HCTL-2001 is a CMOS ICs that performs the quadrature decoder, counter, and bus interface function. The HCTL-20XX family is designed to improve system performance in digital closed loop motion control systems and digital data input systems. It does this by shifting time intensive quadrature decoder functions to a cost effective hardware solution.
