• Provides flexibility in choice of output data
• This decoder will help to reduce the processing power to release the microprocessor load in decoding the encoder signal. Thus, it allows the processor to increase its capacity and run at faster speed.
• No external hardware (counter) is required
• Capabile of filtering all external encoder signal noise
• Provides design flexibility. PLCC packages need less space on system boards

Description

The HCTL-2001 is a CMOS ICs that performs the quadrature decoder, counter, and bus interface function. The HCTL-20XX family 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 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-2001 contains 12-bit counter and provides TLL/CMOS compatible tri-state output buffers. Operation is specified for a temperature range from 40 to +85°C at clock frequencies up to 14MHz. The HCTL-2001 is compliant to RoHS directive and had been declared as a lead free product.

HCTL-2xxx series is a direct drop-in replacement for HCTL-2000,HCTL-2001,  HCTL-2020 and HCTL-2016 which has been obsoleted. It is a CMOS IC that performs quadrature decoding, bus interfacing and counter functions. HCTL-2xxx series is designed to improve system performance in digital, closed loop motion control systems and digital data input systems. The highlight of our ICs is, customers can easily upgrade their existing HCTL decoders with this direct drop-in. Also, with the use of Schmitt-triggered CMOS input and input noise filter, it allows a more reliable operation in a noisy environment. This product is suitable for machine control manufacturers such as servo motors applications.
