Specifications

33 MHz Clock Operation-Typically operates between 2MHz and 33MHz allowing the flexibility of operation with a wide range of motor speeds

Single or Dual Axis Support-One HCTL-2032 IC can support single or dual axes. Hence the benefits in terms of less components on board and cost savings are inevitable

32-Bit Binary Up/Down Counter-The large counter allows the IC to operate without the support of extra memory. This feature reduces the number of supporting components needed on board and in turn is a cost saving.

Operating Temperature: -40 degrees C to 100 degrees C - The wider operating temperature range makes the IC suitable for industrial automation operations which typically apply similar temperature ranges. This feature is not available in our existing products and also our direct competitors product range.

Description

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-2032 provides LSTLL compatible tri-state output buffers. Operation is specified for a temperature range from 40 to 1000C at clock frequencies up to 33MHz.The HCTL-20XX-XX is CMOS ICs that perform the quadrature decoder, counter, and bus interface function. The HCTL-20XX-XX 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-20XX-XX 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. The HCTL-20XX-XX contains 32-bit counter and provides LSTLL compatible tri-state output buffers. Operation is specified for a temperature range from -40 to +100at clock frequencies up to 33MHz.

The HCTL-2022 and HCTL-2022-SC have dual-axis capability and index channel support. Both devices can be programmed as 4x/2x/1x count mode. It also provides quadrature decoder output signals and cascade signals for use with many standard computer ICs.

The HCTL-2022 has most of the HCTL-2032 features, but it can only supports single axis and fixed at 4x count mode. The HCTL-2022 doesn't provide decoder output and cascade signals.
