HCTL-2017-PLC

Quadrature Decoder/Counter Interface ICs

Description

HCTL-2xxx series is a direct drop-in replacement for HCTL-2000, 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.

Benefits

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
