HCTL-2022 Quadrature Decoder IC _ BDTIC a Leading Distributor in China

HCTL-2022 Quadrature Decoder IC

The HCTL-2022 is CMOS ICs that perform the quadrature decoder, counter, and bus interface function. The HCTL-2022 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-2022 consists of 4x/2x/1x-quadrature decoder, a binary up/down state counter, and an 8-bit bus interface. The HCTL-2022 has the dual-axis capability and index channel counter. The use of Schmitt-triggered CMOS inputs and input noise filters allows reliable operation in noisy environments. The HCTL-2022 contains 32-bit counter. It also contains quadrature decoder output signals and cascade signals for use with many standard computer ICs. The HCTL-2022 provides LSTLL compatible tri-state output buffers. Operation is specified for a temperature range from -40 to 100°C at clock frequencies up to 33MHz.
