HCTL-2017 and HCTL-2021
Quadrature Decoder/Counter Interface ICs
Data Sheet
Description
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.
The HCTL-2021/2017 consists of a quadrature decoder logic, a binary up/down state counter, and an 8-bit bus interface.
The use of Schmitt-triggered
CMOS inputs and input noise filters allows reliable operation in noisy environments.
