HCTL2021 Overview
The HCTL-2021/2017 is CMOS ICs that performs the quadrature decoder, counter, and bus interface function. The HCTL-2021/2017 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.
