HCTL-2001-A00, HCTL-2017-A00 / PLC, HCTL-2021-A00 / PLC Quadrature Decoder/Counter Interface ICs Data Sheet Description Features The HCTL-2xx1(7)-A00/PLC is CMOS ICs that performs Interfaces Encoder to Microprocessor the quadrature decoder, counter, and bus interface 14 MHz Clock Operation function. The HCTL-2xx1(7)-A00/PLC is designed to improve system performance in digital closed loop High Noise Immunity: motion control systems and digital data input systems. Schmitt Trigger Inputs and Digital Noise Filter It does this by shifting time intensive quadrature 16-Bit Binary Up/Down Counter decoder functions to a cost effective hardware solution. The HCTL-2xx1(7)-A00/PLC consists of a quadrature Latched Outputs decoder logic, a binary up/down state counter, and an 8-Bit Tristate Interface 8-bit bus interface. The use of Schmitt-triggered CMOS inputs and input noise filters allows reliable operation 8, 12 or 16-Bit Operating Modes in noisy environments. The HCTL-2001-A00 contains Quadrature Decoder Output Signals, Up/Down and 12-bit counter and HCTL-2017-A00/PLC or HCTL-2021- Count A00/PLC contains 16-bit counter and provides TLL/ CMOS compatible tri-state output buffers. Operation Cascade Output Signals, Up/Down and Count is specified for a temperature range from 40 to +85C Substantially Reduced System Software at clock frequencies up to 14MHz. 5V Operation (V V ) DD SS The HCTL-2021-A00/PLC provides quadrature decoder output signals and cascade signals for use with many TTL/CMOS Compatible I/O standard computer ICs.
