The HCTL-20XX family is designed to improve system performance Devices Part Number HCTL-2000 HCTL-2016 HCTL-2020 Description 12-bit counter.
14 MHz clock operation.
All features of the HCTL-2000.
16-bit counter.
All features of the HCTL-2016.
Quadrature decoder output signals.
Cascade output signals.
Package Drawing A A B ESD WARNING: Standard CMOS handling precautions should be observed with the HCTL-20XX family ICs.
5965-5894E 2-178 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 entire HCTL-20XX family consists of a 4x quadrature decoder, 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.
The HCTL-2000 contains a 12-bit counter.
The HCTL-2016 and 2020 contain a 16-bit counter.
The HCTL-2020 also contains quadrature decoder output signals and cascade signals for use with many standard counter ICs.
The HCTL20XX family provides LSTTL compatible tri-state output buffers.
Operation is specified for a temperature range from -40 to +85°C at clock ...
