HCTL-2032-SC

The main function of the HCTL-20XX-XX CMOS ICs is to perform quadrature decoding, counting, and bus interface functions to improve system performance in digital closed-loop motion control systems and digital data input systems. These ICs shift time-intensive quadrature decoding functions to a cost-effective hardware solution, consisting of a quadrature decoder logic, a binary up/down state counter, and an 8-bit bus interface. They also provide reliable operation in noisy environments with Schmitt-triggered CMOS inputs and input noise filters. Additionally, the HCTL-20XX-XX ICs contain a 32-bit counter, LSTLL compatible tri-state output buffers, and operate at clock frequencies up to 33MHz.

The applications mentioned for the Agilent HCTL-2032, HCTL-2032-SC, and HCTL-2022 Quadrature Decoder/Counter Interface ICs in the document are as follows: - Interface Quadrature Incremental Encoders to Microprocessors - Interface Digital Potentiometers to Digital Data Input Buses

The HCTL-2032 and HCTL-2032-SC ICs have dual-axis capability, index channel support, and can be programmed as 4x/2x/1x count mode. They provide quadrature decoder output signals and cascade signals for use with standard computer ICs. They operate at clock frequencies up to 33MHz. On the other hand, the HCTL-2022 supports single axis only, is fixed at 4x count mode, and does not provide decoder output and cascade signals. It also operates at clock frequencies up to 33MHz.
