HCTL-2021 (HCTL2017 / HCTL2021) Quadrature Decoder/Counter Interface ICs

HCTL-2021 (HCTL2017 / HCTL2021) Quadrature Decoder/Counter Interface ICs

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 deco.
